Analysis of Water Quality and Control Countermeasures of Yazidang Reservoir in Ningxia, China

Abstract:

Yazidang Reservoir is a pumped-storage reservoir for water supply in Ningdong Chemical Industry Base of Ningxia, China. It plays an important role as a source of drinking and industrial water supply. Analysis of the water quality from March 2013 to May 2014, the results show that: For organic descriptors, value of COD_Cr, COD_Mn and DO can satisfy with class III, but some values of BOD₅ exceed the standard limitation. For index of nutrients, some values of TP exceed the standard, and TN greatly exceed the standard limitation. Using potential eutrophication to evaluate the reservoir water quality, the results show that Yazidang Reservoir is on a very high level of nitrogen and phosphorus nutrition, reach to level of eutrophy-extremely eutrophy. Considering the current situation of water quality in Yazidang Reservoir, some countermeasures should be carried out for pollution prevention and control of water quality, such as strengthening management, enhancing water quality monitoring and water quality evaluation, simulation, eutrophication control and estimation environmental capacity of reservoir.
