摘要：江西某工業園污水處理廠(規模：5000 m3/d)，工業廢水成分較復雜，水質可生化性較差， COD、SS、氨氮及總氮超標，二級處理后污水無法達到一級B標排放。深圳清泉在現有的處理工藝基礎上增加“AR（反應池）＋CFC（側向流高效沉淀池）＋MDF（多功能深床濾池）”工藝和智能模塊化水處理標準件產品進行廢水深度處理，實際出水COD、SS、總氮達到《城鎮污水廠污染物排放標準》（GB18918-2002）一級A標準，且氨氮、總氮的去除效果≥40%（深度處理部分）。該項目具有建設周期短（項目總工期30天），投資成本低，占地面積少，工藝停留時間短（工藝總提留時間55min）和運行成本低（運行費用不超過0.28元/噸水）的優勢。

Abstract: The sewage treatment plant of an industrial park in Jiangxi (scale: 5000 m3/d), whose composition of industrial wastewater was complex, and the biodegradability of quality was poor. The overproof COD, SS, ammonia nitrogen and total nitrogen couldn’t reach the standard discharge after secondary treatment.Based on the existing treatment process, Shenzhen Qingquan Water Industry Co. Ltd applied a process of ”AR (Reaction pool) + CFC (lateral flow high efficiency sedimentation tank) + MDF (multi-function deep bed filter)” to treat the sewage ,combining with intelligent modular water treatment standard products.After the treatment, the index (COD ,SS and total nitrogen) of the effluent could reach the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater treatment Plant (GB 18918-2002),and the removal rate of ammonia nitrogen and total nitrogen was more than 40%(the part of advanced treatment).The project completed with some outstanding characteristics, such as short construction period (total project duration of 30 days), low investment cost and less land occupation,short process stay time (55min) and low operating cost (operating costs not more than 0.28 yuan / tonnes of water).
Key words: the sewage treatment plant of an industrial park; CFC module; MDF module; the first level A
