漂浮植物塘协同处理农村分散生活污水研究
Research on aquatic floating plant cooperating with septic tank for rural domestic wastewater treatment
摘要
Abstract
A process cooperating aquatic floating plant ponds with septic tank for rural domestic wastewater treatment was studied. The results indicated that Eichhornia crassipes,Pistia stratiotes,Potamogeton crispuses ponds all have good effects in the process for the wastewater purification. Eichhornia crassipes pond has the best effect on total phosphorus removal. Pistia stratiotes pond has the best effect on total nitrogen and ammoniac-nitro-gen removal. When hydraulic retention time of the aquatic floating plant ponds was 20 d,the contents of main contaminants were lower than the criteria of the reuse of urban recycling water for watercourse of aesthetic envi-ronment use (GB/T 18921-2002). Planting floating plants in ditches in rural areas may be an applied measure to form a practical system for rural domestic wastewater collection and treatment,which employs septic tank and ditches growing floating plants for rural domestic wastewater & storm-water collection and purification.关键词
