Theory Of Water Resources Protection In Shaanxi Section Of Weihe River And Its Countermeasures

Weihe River is the mother River of people in Shaanxi Province, is also one of the cradlesof the Chinese civilization. Shaanxi’s economic and social development, poor in waterresources of Weihe River, supply-demand contradiction highlights River ecological watershortage, water pollution problem is getting highlights. Shaanxi Provincial Committee, theprovincial Government attaches great importance to the Weihe river pollution control work,always put the pollution of Weihe River in the province’s economic and social development,food security and social harmony and stability in an important strategic position. This inanalysis Weihe River hydrological water resources characteristics of based Shang, using Riveris satisfied that dirt total control for mainline of river basin ecological protection method,established has a dimension River pollutants calculation model, to water features district forcontrol unit, on Weihe River River Shaanxi paragraph water features district designhydrological parameter, and is satisfied that dirt capacity and the district is satisfied that dirtred line control indicators for has research calculation, made has most strictly of waterresources management system water features district limit is satisfied that dirt red line controlprotection theory, And protecting theories put forward countermeasures to solve the waterpollution problem of Weihe River. The main results achieved are as follows:(1) Analysis of the design of Shaanxi section of Weihe River hydrological parameters. This accordingto national on water features district is satisfied that dirt capacity approved of technology requirements andwaters is satisfied that dirt capacity calculation procedures under (GB/T25173-2010) of provides, selectWeihe River River Shaanxi paragraph of forest home village, and Wei Jiabao, and xianyang, and Lintongand Hua county, main control hydrometric station long series measured flow information, usinghydrological statistics method on over most blight months flow for statistics, while using experiencefrequency formula for row frequency calculation, came90%guarantee rate over most blight months flowas design flow. And using hydrologic station measured flow rate, flow rate data, establishing flow-velocitycurve, determined that design under the design flow velocity.(2) Calculation of Shaanxi section of Weihe river water environmental capacity of the Ribbon. Thisaccording to Shaanxi Province water features Division under on Weihe River River Shaanxi paragraph thewater features district of divided and water target value, and combined2008Shaanxi Province hydrologicalwater resources survey Council completed of Shaanxi Province Yellow River basin into river sewagemouth Census Registration report under in the on Weihe River River Shaanxi paragraph sewage mouth andsewage volume of census results, basis waters is satisfied that dirt capacity calculation procedures under (GB/T25173-2010) on River basic situation of almost of provides, by calculation analysis decided usedRiver a dimension model for almost of calculation, Drew the water function area and the districts of CODand ammonia nitrogen pollution receiving capacity value.(3) On Shaanxi section of Weihe river water function zone theory of pollution receiving capacitycalculation and mathematical model of hydrological data selection and parameters determination ofreasonable analysis and inspection. Results indicates that, hydrological data for the hydrometric stationmeasured information, and after has information integration, reliable, and reasonable; mathematics modelof selection is according to this on table3.1calculation came Q value for143m3/s, and waters is satisfiedthat dirt capacity calculation procedures under (GB/T25173-2010) Dang Q is less than150m3/s Shi canused a dimension mathematics model to calculation waters of is satisfied that dirt capacity of provides,integrated selection of; parameter of determines is using has measured and analogy analysis two speciesmethod, By water quality and pollution receiving capacity calculation result changes along trend analysis todetermine their legitimacy.(4) Identified Ribbon Shaanxi section of Weihe river water limit pollutant red linecontrol and management indicators. This in calculation came Weihe River River Shaanxiparagraph the water features district and the the district is satisfied that dirt capacity of basedShang, according to pollutants into Wei investigation results, to water features district forcontrol unit and research object, to investigation of status into river volume and water issatisfied that dirt capacity for control basis, according to both of size relationship determinesWeihe River River Shaanxi paragraph water features district limit is satisfied that dirt red linecontrol management indicators. That is: If the present situation into a river is less than waterpollution receiving capacity, then the status quo into the River as the main streams of WeiheRiver in Shaanxi Province water function zone limit pollutant red control indicator if volumeis greater than the water environmental capacity of status into the River, the water bodypollution receiving capacity as the main streams of Weihe River in Shaanxi Province waterfunction zone limit pollutant red line control and management indicators.(5) For Shaanxi section of Weihe river water resources management and engineeringmeasures of protection. This in analysis research and made Weihe River River Shaanxiparagraph water resources protection theory of based Shang, according to in the, and provinceof requirements and deployment, and combined currently my water resources protection workof content and actual, made has water features district limit is satisfied that dirt red linecontrol, and "Twelve-Five" water features district standard management, and strengtheninginto river sewage mouth and the water regulatory capacity, management countermeasures andguarantees ecological base flow of adjustable water engineering, and water ecological systemprotection and repair engineering, engineering countermeasures. Presented is Shaanxi section of Weihe river water resources protection management countermeasures for software andsystem construction, engineering countermeasures proposed is Shaanxi section of Weihe riverwater resources protection hardware and capacity-building, both are indispensable. Thisarticle argues that, at present serious water pollution in Weihe River, only two measures andtwo measures of management and engineering to get harder, to completely solve the waterpollution problem of Weihe River.
