| Abstract: | Two levels of biochemistry processing water leakage of shipyard is treated with coagulation precipitated filtering process. The operational result shows that the process is efficient and stable. The effluent quality can meet the standard of wastewater reuse（ GB/T 18920 -2002） and 《water quality standard for scenery and recreation area》. The main pollution indexes could meet Ⅳ standard of GB3838 -2002（Surface Water Environment Quality Standard,except the concentration of TN, BOD5. The mineral oil of the effluent quality can meet the Ⅰ standard, dissolved oxygen, COD and ammonia nitrogen can meet Ⅲ standard. |
