REVIEW OF WVATERQUALITY OF WEIHE RIVER Review of Water Qualitv of Weihe River

Weihe River origins from the Wushu Mountain in Weivuan Count Gansu Province, flows across three provinces, Gansu, Ningxia and Shaanxi. and converges to the Huanghe River at Tongguan. It is the largest branch with the 8 18 km of the length, I- .477km: of the total basin area and 502km of the length in Shaanxi Province. The annual run-off is 7.63 billion m3 and the annual sediment run-off is 0.423 billion tons. At thiemiddle and dow,nstream of Weille is the rich Guanzhong Plain. On tihe main stream three irrigyationdiversion kev projects have been constructed and they are Baojixia plateau-up diversion project located at the Baoiixia narrow, Baojinxiaplateau-bellow diversion project located at XVeiiiabuand Jiaokou project fOrpumping ftrom'WVeihe River. The followino is the reviews of the water qualitv of the water svstem otfV;eihe rver ( Shaanxi section . 1. Dividing of the water function domains on the round According to the local standard of Shaan.xiprovince DB 61-224-1996, zhe wxaterfunction domains of the main stream of Weihe River are divided as the following table (table I-I).

Also there are some Mareriais ascribe it to -reoloaical factors of this domain. -4) The ammonia nitrogen pollution is Serious in the whole Weeihe River, it mavbe caused bv the sanitarv and waste water witlh ammonia and itrroen disclharged bv the nitrogen fertilizer factories along the Weilie Ril er. MMost of the pollution of Weihe River is organic. The main pollutant materials are pennanganate index, BoD5, petroleum, ArOH. etc. .And among them the permanganate index and petroleum are perenniallv class IV and V. and even exceeding class V. Controlling the pollution of Weihe is to control the poilution indexes of the above organic pollutant materials. (6) According to the grot.nd water quality, Weihe River has been poliluted seriousiy but the pollution degrees of different seasons lhas not exceeded the state standard Water Quality Standard for Irrigation (GB5084-85). So of the Weihe River has not lost the main function of the water. Monitoring RZesultsof Water-Q uality of Weilie at Eacht Sectioni in Eachi Seasoii of 1996 (ingtI L

Leaching using water from Weihe is to be proceeded ( keeping the depth of the upper water layer 2 cm ) .The upper leaching was started at 10:20 on July 31 rn 1998 . Dripping started from the upper hole at 5:00 on August 1 in 1998 , from the middle hole at 7:40, and from the lower hole at 9:10 . Drip bottles with the capacity of 800 ml were placed to collect the water from each :ci-cl. ''n August 3 in 1998, there had been water of 600 ml in the upper bcotle at 9K:'5, in the middle bottle at 16:40, and in the lower bottle at 17:3_. So the Dripping speed is different. The leaching test used water of 7000Om1 .T-he ;ripp ing speed at each hole were calculated as O. 17mi/min , t:e ^._ mn/minat the middle, and 0. 17 ml/min at the lower.

Agricultural EnvironmentQuality Rev.ew Of Guanzhong Irrigation Districts Agricultural Environment Quality Review N. Of Guanzhong Irrigation Districts

The monitoring data of water and soil of the irrigation disti.cts are applied to review the agricultural environment which are r-^m the environment protection station of Shaanxi Province. 1. The monitoring and analysis method of the agricultural envirz.mer. 1.1 According to the source of irrigation water and the a`- : w:e review, the sample positions are set in the representative domains in te

lrigatorn districts. There are 12 waLer quality monitoring sec::on"SS5_ soil monitoring positions and 9 crop sampling positions. 1.2Sa piing method. Wlater quality samples are collected from the e;hanne's ano .-e water sources in irrigation seasor, and fixer are added at t-Hesize. .- e soil sampies are collected in the harvest season, and the foilowiLg s u-e mnet o. Around the monitoring position, 5 pieces of lan re se:ez:c v soi: sam:pes are zoliectecaccordi-.g to tie diagonai -rzcess, --e- mix.ng o: -he samples, 1 kg of the mixture soil are col ece, agged with a label , and took back to the lab. The crop samples are zoilect.edat the sa.me i..e and ,si;.g the same method of the soil sam:Ung, .- _ of the oro sample are collected, 10 kg of the fruit samipe are zo_i:ec.. Thedetih of the soil sampling is 3-20 cm for crcp aaneit .; for 4:r i+4.1eC. 1.3 I reatment of the samples. 7he water sampies must be refrigerated and tested as soc- as prossibie. The soil sampies must be air dried in the lab, decontaminated, milled, sifted, mixed and finally put into a bottle .c be tested. The crop samples must be air dried and clean the surface deo-sit ujilderand then dried, milled, and put into a bottle to be teste. 1.4 Monitoring of the existing condition of environmnetai quality.

The industrial waste liquid of Tianshui is discharged into Weihe. This is the main pollution 3ou.ce so that sometimes there is bubbies and black liquid amPearingabout the section of the border between Shaanxi and Gansu. 2.6.2 in Baoji County (i 3ndustrial pollution source According to the investigation, there is no ndustrai ente--ses :n we zounty, and no poiluticn source. At the left bank of Weihe, there is a nationai -e..ense storehouse above the elevation of 644.Omand 6km away from the dam. Trhe waste water from the storehouse is not pollutant because the storehouse checks itself every year.

The sediment particle will absorb organic ard grea: anlt zf heavy metal while sinking. The absorbed heavy metal is not easy toe esese.and will not causethe secondpollution. At the beginning of the filling of the reservoir, s^me wee-s, organic materials and humic matter will be submerged, and then decay and discomposed. The nutritional salt will accumulated and is advantageous to the phytoplankton bloom and development. The oxygen in the water will be consummated. B3utthe runoff is larger than the capacity of the reservoir, and the turbulent and mixing fluctuation is strong, the oxvgen will be rapidly added to the waters, and the water quality of the reservoir will not deteriorated. The nutrition depends on the concentration and demurrage of the nutritional salt. After the gate is added , The reservoir is an incomplete annual adjusting reservoir with the capacity of 32 million m3.When the reservoir discharae sediment during July to October, the nutritional salt, oxygen and phosphorous, accumulated in the reservoir will be discharged as the sediment. The concentration of nutritional salt will be reduced. Germanv and Holland defines the normal nutrition as COD = 5 m.g/L. The COD concentration in the water of Weihe is 3.3 mg!L, and will reduce by self-cleaning. So the water of the reservoir is poorly nutritional. 3.3 Analysis of environmental capacitv of waters The organic COD is selected to evaluate the environmental capacitv of waters. The calculation mode is as the following.

The minor is the toxic gas and mill dust of the off gas of the vehicle and the fuel oil of the construction machinery. The artificial drilling biast is applied in rock excavation. According to the monitoring in the construction of Longyangxia project, the density ^f MilI dust is 40 g/m3 while drilling dry pores using air drill ( 20g/rn3 for wet pores), ard 8o-og/m 3 wtwhiledriiling dry pores in foundation pit, and exceeed -:near quality standard of environment of GB3095-96.

Tle noise comes from the construction blast, the machinery in {re auxilierv factories and the vehicles. The living quarters lies on the terrace 625.0m west to the cottage of Taivin, and 600m away from the blast position. The noise will not poilute the environment because of the prevention of the mountains, diffusion and fading in -he-air ofthe soundwave although the noie6leverrshigYh.See tie n6i-se1 eVe"sof` the major construction machinery in table 3-2.

Srince R3 sx drainage system, Duanjia, Zhaogong, Zhousu, Zhaozhen, Dianzhang, and Dizhang, had been built, and the area of naked underground water has been controlled, reduced to 390 ha in 1989. 3.6.2 Analysis of the influence of the irrigation' compiement of tfhe reservoir on the environmenL (1) The water shortage of the plateau is great. After the gate-added engineering finished, 80 million m3 of water will be complemented to the plateau and release the water shortage of the irrigation district. According to the irrigation experience of the district, the irrigation can greatly increase 'he yields of grain and oil crops. While the gate-added engineering finished, the reservoir can complement water, the peasants can irrigate at proper. t:me, 'he agncaltura2 yield will be high and stable. the ecologicai environment will e improved as well.

Following the flow direction o-f the _ .e u.. water of -he district, from northwestern to southeastern, scme of the increasec ischarged water will flow as underground runcff, to _.1_ele.- the overexploited underground water of the irrigation area below the plateau. (4) The underground water level of the irrigation district on the plateau keeps rising perennially, and the complemented water from the reservoir will greatly accelerate the rising speed of the underground water. According to the analysis and calculation of the existing data, the perennial increment of the rising speed of the underground water is 0.24m. The environmental problems

caused by the rising of the underground water level concent-ated, accordi.ng'G the analysis of the land form and geology of the district, in the bottom lands, such as Duanjia, Zhaogong, Zhousu, Zhaozhen, Dianzharg and Dizhang, etc..
