Analyse On The Character Of Municipal Wastewater Quality In Wuhan

In the last several decades, reform along with our country to open gradually thorough, economic structural adjustment in city, the domestic living level increases gradually, exceed into middle-class family living. Its causing the quantity of wastewater in our city to increases gradually, the quality of wastewater take place great change. At the same time, the design of wastewater treat plants only depend on the quantity of wastewater and the quality of wastewater, but unknown currently and future the quantity of wastewater and the quality of wastewater. Unknown the change of municipal wastewater can't confirm the fee and measure to father municipal wastewater. It great influences the municipal environment planning and public utility and economic construction. This thesis advance through inspect the present wastewater quality of the outlet of municipal wastewater and biotope and discharge pipe. Analyse current monitoring date. It can have a overall recognizing of the quality of municipal wastewater. Then can confirm a good plan for construction the wastewater treat plan. It can have a firm base for prevention water pollution.Through investigate the quality of wastewater in Wuhan.From the drain of Shaihu in Wuchang and Luobuzui in Qinshan and Huangxiaohe in Hankou we can know that average discharge loading density in Wuhan: CODCr 155.97 mg/L; BOD5 61.52 mg/L; SS 65.77 mg/L; TN 22.61 mg/L; NH3-N 15.40 mg/L; TP 2.28 mg/L.The date of discharge loading have great rule.Through the comprehensive analysis of investigate the quality of wastewater and current situation in Wuhan.From the drain of Shaihu in Wuchang and Luobuzui in Qinshan and Huangxiaohe in Hankou we can know that there are large effect to the present wastewater quality in the service area's population density ,the average discharge loading parameters, air temperature, water temperature, the reduce rate of suspension in septic tank, industrial waster water, the infiltrate rate of underground water to discharge pipe and so on.This thesis advance through inspect the present wastewater quality of the outlet of municipal wastewater confirm the wastewater quality change with month model and the wastewater quality change with day model. Though combine the two models realize precision analyse of quality of wastewater.
