生物慢滤池用于污水深度处理的实验研究
Experiment on advanced purification of sewage with biological slow filter pool
摘要
Abstract
The paper carried out advanced purification experiment on both simulated wastewater and the secondary effluent of a wastewater treatment plant in Xi'an by applying biological slow filter pool .The purification effect was evaluated through the analysis of nitrogen , phosphorus contents and potassium per-manganate indices in the influent and effluent as well as chlorophyll a content in the overlying water and effluent .The results suggested that biological slow filter showed better treatment performance on simulated sewage and the removal rate of total nitrogen , ammonia nitrogen , total phosphorus and potassium perman-ganate index is 66.4%, 40.2%, 66.4%and 73.3%respectively;the removal rate of the secondary ef-fluent of a wastewater treatment plant to which is 35 .1%, 21 .0%, 30 .2%and 12 .6%,the removal rate is lower than that of manual simulated test .Moreover , biological slow filter has good retention effect to chlorophyll a , the removal rate is 93 .4% and 66 .4% respectively .The quality of the reclaimed water treated by the biological slow filter reaches the requirements of water quality standard for scenic environ -ment use .Therefore , the reclaimed water can be re-used as urban landscape water body and prevent the occurrence of eutrophication .关键词
