Water Quality Pollution Characteristics and Comprehensive Prevention and Treatment Measures for Shuiguo lake

For an objective assessment of the ecological environment of Wuhan Shuiguo Lake water quality status,water quality indicators of the four seasons including pH,transparency,ammonia nitrogen,dissolved oxygen,COD,BOD5,nitrogen,phosphorus and etc was monitored in 2009.The results showed that: Shuiguo Lake showed seasonal changes in water pollution,pollution levels in spring and autumn lighter than in summer and winter.By single factor analysis and evaluation of integrated pollution index method,Shuiguo Lake water quality met Ⅴ class(the national surface water quality standard)According to the experience at home and abroad for control pollution in lakes,the water quality of Shuiguo Lake can be recovered.For the Shuiguo Lake recovering,eight comprehensive prevention and cure measure was given in the paper:1)Import the existing sewerage from Shuiguo Lake to East Lake through culvert.;2)increasing the height of the lake water level;3)to restore Shuiguo Lake farming capabilities;4)continue to take water dredged sediment;5)put in benthic organisms to swallow suspended material;6)cultivating aquatic plants communities;7)In the lake to establish the appropriate on-line Water Quality Monitoring System in the Lake to improve water quality;8)To continue conduct useful study for directing production of Portland cement with the sludge.
