摘要
根据理论分析提出生物吸附-沉淀-再生的城市污水处理工艺,即高负荷生物吸附再生法。该工艺对污染物去除的作用主要包括污泥的絮凝作用、吸附作用和生物代谢作用,而以前两者的作用为主。对城市污水的生产性试验研究结果表明,该工艺能够较大程度地提高SS、COD、SCOD和BOD等污染物的去除率,具有明显的处理效果,对于西北干旱缺水地区实现污水资源化是切实可行的方法。
Based on theoretical analysis, a new process to treat municipal wastewater high-loading adsorption biodegradation regeneration process is reported in this paper. This process can remove pollutants mainly by flocculation, adsorption and biological metabolism function and the former two functions are predominant. The municipal wastewater full-scale test results show that the process can increase the removal rates of SS, COD, SCOD, BOD and other pollutants in wastewater. It is a feasible method for arid and water-deficient areas to realize sewage recycle in northwest China.
