摘　　要：为了研究蚯蚓生态池对村庄污水的处理效果,本文通过建立蚯蚓生态池过滤系统,对蚯蚓生态滤池在试验期间对污染物的去除效果,以及不同季节蚯蚓生态滤池处理效果进行了分析。研究结果表明:蚯蚓生态过滤处理可以有效去除污水中的化学需氧量(COD)、生物需氧量(BOD5)和悬浮物(SS),经蚯蚓生态过滤后出水元素数值是相对稳定的;蚯蚓过滤后对污水中的氮和磷具有良好的去除效果,但只有少数样品能满足Ⅱ级排放标准[ρ(TN)≤20 mg/L,ρ(TP)≤3 mg/L]的要求;蚯蚓生态过滤在冬季最冷的时期处理效果显著低于春季和夏季最热的时期,但水中大多元素的数值达到了排放标准。In order to study the treatment effect of earthworm ecological ponds on village sewage,this paper establishes a earthworm ecological pond filtration system and analyzes the pollutant removal effect of earthworm ecological filters during the experimental period,as well as the treatment effect of earthworm ecological filters in different seasons.The research results indicate that earthworm ecological filtration treatment can effectively remove chemical oxygen demand(COD),biological oxygen demand(BOD5),and suspended solids(SS)from wastewater.After earthworm ecological filtration,the effluent element values are relatively stable.Earthworms have good removal effects on nitrogen and phosphorus in wastewater after filtration,but only a few samples can meet the requirements of Class II discharge standards[ρ(TN)≤20 mg/L,ρ(TP)≤3 mg/L].The treatment effect of earthworm ecological filtration is significantly lower in the coldest period of winter than in the hottest period of spring and summer,but the values of most elements in the water meet the emission standards.
