新型生物膜反应器处理垃圾渗滤液可行性研究

以自制新型生物膜反应器为载体,研究了垃圾渗滤液原液进行挂膜的可行性。在温度恒定为(27±1)℃,溶氧浓度不超过5mg/L的条件下,使垃圾渗滤液的COD含量由3560mg/L下降到750～770mg/L,去除率达到78.4%～78.9%。氨氮含量由3124mg/L下降到457～462mg/L,去除率达到85.2%～85.4%。电絮凝体系在3A、20V的条件下工作15min,使垃圾渗滤液COD含量由975mg/L降为217～223mg/L,去除率为77.1%～77.7%,氨氮含量由587mg/L降为141～148mg/L,去除率为74.8%～76.0%。电絮凝起到了很好的处理效果,是新型生物膜反应器经济环保型的辅助处理方式。

Feasibility Research on Treated Landfill Leachate by New Biofilm Reactor

Based on the self-made new biofilm reactor as the carrier,in landfill leachate treatment,the feasibility of membrane hanging was studied.At constant temperature for(27±1) ℃,dissolved oxygen under 5 mg/L conditions,the cod content of landfill leachate was ruduced to 750-770 mg/L from 3 560 mg/L,the removal rate reached 78.4%-78.9%.Ammonia nitrogen content was reduced to 457-462 mg/L from 3 124 mg/L,the removal rate reached 85.2%-85.4%.In 3 A,20 V conditions,electric flocculation system had worked for 15 min.The cod content of landfill leachate was ruduced to 217-223 mg/L from 975 mg/L,the removal rate reached 77.1%-77.7%.The ammonia nitrogen content was reduced to 141-148 mg/L from 587 mg/L,the removal rate reached 74.8%-76.0%.Electricity flocculation played a very good auxiliary treatment effect,which is a new type of biofilm reactor economic environmental protection auxiliary treatment.
