附加处理垃圾渗滤液对水解+缺氧-好氧污水处理工艺的影响

The Effect of Additional Little Treatment of Landfill Leachate on Hydrolysis + A/O Sewage Treatment Process

在急需解决某垃圾发电厂部分垃圾渗滤液的背景下,结合某园区污水处理厂的现有的水解+缺氧-好氧污水处理工艺,该文对该污水处理厂尝试附加处理此部分渗滤液后的水质和成本的变化进行了比较。结果表明,该污水处理厂(当时日均处理量2.3万m3)短期附加处理少量(日均73.4 m3)垃圾渗滤液是可行的,附加处理此渗滤液使吨水处理直接成本增加0.014元,合每吨垃圾渗滤液被附加处理的实际直接费用为6.37元。

In the background of urgent to deal with a part of landfill leachate in a garbage power plant, combining with the existing processing technology of a sewage treatment plant in an industrial park, The article compares the change of sewage quality and the cost after the sewage treatment plant trying to additional treatment of the landfill leachate. As a result, short additional treatment of a small amount （average daily 73.4 m^3 ） landfill leachate in the sewage treatment plant （the daily capacity of 23000 m^3） is feasible, additional treatment of the landfill leachate increases ￥ 0.014 in the direct costs of per ton of sewage.
