摘要:
利用微生物固定化技术原位净化污水是当前的研究热点之一，为明确其在低温条件下的效果，在亚热带地区温度较低的3月份至5月份，采用该技术对富营养化河塘进行净化，监测水质变化。结果表明：采用该技术后水体的氨氮、总溶解氮、可溶性正磷酸盐、总溶解磷浓度较进水口明显降低，在入水氮、磷负荷上升的情况下，仍保持着总体下降的趋势；此技术对总氮、总磷的去除效果没有对总溶解氮、总溶解磷的净化效果明显；采用该技术后，河塘水体高锰酸盐指数稳步下降。说明，在亚热带地区温度相对较低的春季，微生物固定化技术可以用于原位净化城市生活污水污染的富营养化河塘。
Abstract:
The contamination of water in urban rivers and ponds is becoming an increasingly serious problem in China. Research of using microorganism immobilization technology to treat contaminated water is currently one of the hot topics, but little study has been made on in-situ treatment of the domestic wastewater in low temperature seasons. In the present study, a eutrophic pond receiving domestic wastewater was studied for the changes of water quality before and after the technology application from March to May in subtropical climate zone. The changes of NH3-N, NO-3-N, total dissolved nitrogen (TDN), total nitrogen (TN), dissolved orthophosphate, total dissolved phosphorus (TDP), total phosphorus (TP), chemical oxygen demand（CODMn）, turbidity and chlorophyll-a concentrations were monitored periodically, together with the parameters of water temperature, pH and dissolved oxygen (DO). The results showed that the concentrations of NH3-N, TDN, TDP and dissolved orthophosphate in the pond water were reduced significantly compared with the water from the pond inlet. Although there was an increase of N and P load from the inlet water, the concentrations of NH3-N, TDN, TDP and dissolved orthophosphate in the pond water generally kept a declining trend. The reductions of TN and TP concentrations were less than tose of TDN and TDP. The concentration of CODMn (-15 mg/L) was high in the pond water before treatment, but gradually declined to 3.0-4.6 mg/L after treatment. In summary the microorganism immobilization technology is applicable for in-situ treating domestic wastewaters in early spring within subtropical climate zone. 
