Heilongjiang Nen water conservancy project. River water diversion project environmental impact analysis is the construction of a very important research topic, with quite significant diversion project on the feasibility of the decision-making. In this paper, Nierji Hydro built to run as a precondition for the expansion of Heilongjiang Nen a project on the impact of the Nen River water environment were studied. The study includes: a project to predict the impact of the Nen River hydrological regime, a project the Nen River water quality impact analysis. Paper a numerical simulation model, developed by the Danish Hydraulic Institute's MIKE11 software for solving the model to predict the impact on the water regime; the use of comparative analysis method to evaluate the impact on water quality. By studying that: the impact of a project on the Nen River diversion of river runoff mainly by Nierji reservoir drainage control, the Nen River in downstream water flow has a relatively large change in the special dry years (p = 90%) of 8 , 9,10 80 type slag machine manufacturers, the Nen River diversion impact on hydrological regime is large, there is no impact of non-diversion period, Qiqihar Fulaerji section driest month flow to meet 35m ~ 3 / s river water environment requirements; changes and increased irrigation return flow of the hydrological regime of the Nen have some impact on water quality.巩义鑫 China is producing professional manufacturers Cinder Cinder factory price, willing to sacrifice power livelihood projects to this end! Darfur river diversion project is located in Liaoning Province, the new Bin Cinder machine manufacturers agent, is quoted Hun River tributary river of the water supply in Darfur, Shenyang, Shenzhen Yong ha of small water projects. The project is long discharge structures 1 56m free-overflow spillway gate control without its weir height of only 1.2m wide single design flow of 0.17 a 12m3 / (S · m), maximum head of 2.68m on the downstream water level difference is small, 巩义鑫 China is producing slag professional manufacturers willing to sacrifice power livelihood projects to this end!
