- 摘要:
- 以常州市新橋鎮(zhèn)藻港河西支為治理對(duì)象,遴選深層微孔層流曝氣、微生物強(qiáng)化降解、生態(tài)浮島等技術(shù)進(jìn)行集成,對(duì)該黑臭河道進(jìn)行治理與生態(tài)修復(fù)。第三方機(jī)構(gòu)水質(zhì)檢測(cè)結(jié)果表明:該工程經(jīng)過(guò)5個(gè)月的調(diào)試運(yùn)行,河道水質(zhì)狀況明顯改善,總磷、氨氮和COD的去除率分別達(dá)到84.4%、98.6%和65.3%,治理后達(dá)到地表水Ⅳ類(lèi)水質(zhì)標(biāo)準(zhǔn)。工程實(shí)踐證明,該集成技術(shù)能夠有效去除黑臭水體中的有機(jī)物、氨氮、總磷等污染物,增加水體透明度和溶解氧。通過(guò)建立長(zhǎng)效管護(hù)機(jī)制,可從根本上恢復(fù)河流生態(tài)系統(tǒng),進(jìn)而改善和維護(hù)水質(zhì)。
- Abstract:
- An integrated system of bottom laminar flow aeration, biological enhanced degradation, and ecological floating islands was used to treat the west branch of Zaogang River in Xinqiao Town, Changzhou. The testing results by the third party showed that the water quality in the river was significantly improved after five-month treatment. The average removal rates of TP, NH+4-N, and COD have reached 84.4%, 98.6%, and 65.3% respectively. The water quality was better than level Ⅳ in Environmental Quality Standards for Surface Water(GB 3838-2002). Practice has proved that this integrated system could effectively remove pollutants such as TP, NH+4-N and COD in the black-odorous river, increase water transparency and DO. Through the establishment of long-term protection plan, it could fundamentally restore river ecosystems and improve the water quality.
