Discussion on Countermeasures and Measures of Water Environment in Mountain City
Gailanxi in Chongqing is a tributary of the Yangtze River,which is a typical mountain rain source channel,but the effect of rectification is not obvious.The project to irrigation rings river implementation quasi Ⅳ class water quality(except TN,other indices reaches class Ⅳ)as the project goal,the background research master the culvert water quality,water,small,since the river capacity is weak,the source of wastewater diversion is not thoroughly,groundwater pollution and heavy,sediment deposition,system management scheme using the source source wastewater+terminal treatment technology,source wastewater diversion transformation to reduce pollution load,the end of building water quality station treatment of residual wastewater,and realize the river water function.After transformation in river starting point of Xinhua water quality station process,water meet the needs of river daily ecological hydrating,the end of the new irrigation stream water quality improvement station treatment residual wastewater,have the function of river water quality rapid update after rain,two water quality station water quality meet quasi Ⅳ class standard,through online monitoring flow data to predict water quality treatment station scale has innovative significance in the industry.Through the treatment of Gailanxi,the black odor has been completely eliminated,and the beautiful scene of green water and fish in shallow bottom has been reproduced.
