Abstract:

The mechanism of coagulation,sand filtration and active carbon adsorption are introduced and the process-selecting reason is expounded. The number,type and price of the equipment and the number, size and other parameters of the structures are specialized. The economic benefit analysis indicates $70 200 is economized every year. The result of actual motion indicates that the COD_Cr,BOD₅ and SS in the discharged water absolutely meet the requirements of provincial first class effluent discharge standard and the second class effluent standard GB 8978-1996.

Key words: coagulation, sand filtration, active carbon adsorption, junked plastic cleaning wastewater

摘要：

通过混凝、砂滤以及活性炭吸附机理介绍,阐述选择该工艺的理由;列举了主要设备数量、型号、价格与构筑物数量、规格尺寸等相关参数。经济效益分析表明,每年节约水费70200元;实际运行结果证明,各单元状态稳定,出水中的COD_Cr、BOD₅和SS完全达到地方一级排放标准以及GB8978-1996中的二级排放标准要求。
