摘要: 以南方地区水稻田为载体,构建低负荷耕作型水稻田湿地,考察水稻生长周期内不同水力负荷(HLR)条件下的COD、总磷、氨氮、总氮等污染物去除规律,并利用模糊综合评价法对稻田排水水质进行综合评价。结果表明,水稻分蘖期后,装置的净化效果提升了4%~13%;当水力负荷为0.065 m3/(m2·d)时,耕作型湿地对COD、总磷、氨氮、总氮的去除率分别达47.3%、84.0%、80.0%、68.5%;模糊综合评价表明稻田排水水质优于普遍农村污水设施的《城镇污水处理厂污染物排放标准》GB18918-2002中的一级A标准。

Abstract: Low-load cultivated paddy field wetland was constructed by using paddy fields in the south, and the removal laws of COD, total phosphorus, ammonia nitrogen, total nitrogen and other pollutants under different hydraulic loads (HLR) in rice growth cycle were investigated. Fuzzy comprehensive evaluation method was used to evaluate the drainage quality of paddy field. The results showed that the purification effect of the plant increased 4%~13%; When the hydraulic load was 0.065 m3/(m2·d), the removal rate of COD, total phosphorus, ammonia nitrogen and total nitrogen was 47.3%、84.0%、80.0%、68.5%, respectively. The fuzzy comprehensive evaluation shows that the drainage quality of paddy field is better than that of the Pollution discharge standard of urban sewage treatment plant in the GB18918-2002 of general rural sewage facilities.

Key words: tillage type wetland, nitrogen and phosphorus, paddy field, hydraulic load(HLR)
