常规的污水处理办法有以下几种:
1. 生物化学法,如活化污泥法(activated sludge process),生物结层法(fixed biofilm processes),混合生物法(combined biological processes)等;2. 物理化学法,如粒质过滤法(granular media filtration),活化炭吸附法(activated carbon adsorption),化学沉淀法(chemical precipitation),膜滤/析法(membrane processes)等;
3. 自然处理法,如稳定塘法(stabilization ponds),氧化沟法 (aerated or facultative lagoons),人工湿地法(constructed wetlands)。
