人工快渗系统处理生活污水强化除磷试验研究

Study on Enhanced Phosphorus Removal of Domestic Sewage by the Constructed Rapid Infiltration System

随着经济的发展,我国的水污染已经处于一个相当严重的局面。虽然人工快渗系统在我国低海拔地区应用较为广泛,但在高海拔地区尚处于试用阶段,很多化学、生物过程尚不清楚并存有争议,同时许多技术问题尚未得到很好解决,仍需进一步研究和探讨。基于以上背景,本试验以昆明学院人工快渗系统为对象,研究不同填料对污水的处理效果和人工快渗系统对不同浓度生活污水的去除效果。研究表明,该快渗系统对污水中总磷的去除率较高,平均去除率达到了86%以上;以钢渣为填料的快渗系统对总磷的去除稳定性优于以天然河砂为填料的快渗池。

Along with economic development, the water pollution in China is already in a pretty serious situation. Although artificial constructed rapid infiltration system is extensively applied in low altitude areas in China, but at high altitude it is still at the trial stage, many chemical and biological processes are unclear and controversial, and many technical problems are not solved yet, they still need to be further studied and discussed. Against this background, taking the constructed rapid infiltration system of Kunming Institute as a research subject, the effect of different fillers on wastewater treatment was studied as well as removing effect of constructed rapid infiltration system for different concentrations of sewage. The results show that the rapid infiltration system has higher total phosphorus removal rate, average removal rate is above 86%;the rapid infiltration system with steel slag as filler has better stability than that with natural sand as filler.
