鏡湖區整治黑臭水體初見成效

【摘要】:

城市水體為何變臭了

據悉,鏡湖區共有10條水體被列入到環境部、住建部的城市黑臭水體整治清單,分別是袁澤橋主溝、旭日天都水系、西洋湖西側明渠、西洋湖、板城垾支溝、保興垾文化路支溝、板城垾主渠、保興垾主渠(九華北路-江堤)、保興垾大富支溝、浴牛塘。其中多條水體經過治理已經初見成效。

二是內源污染持續釋放。如雨洪過后,保興垾和板城垾的底泥上翻比較明顯,主要是由于雨洪期間河道流速快、水位降低、上覆水深變小。三是城市水生態功能減弱。如河道水位隨季節性變化較大,旱季缺乏清潔生態補水,水環境容量低;水動力條件差,旱季基本處于靜止狀態;以傳統硬質岸線為主,基本無沉水植物和挺水植物,生態系統脆弱。

 

六條水系整治已初見成效

今年10月底,板城垾完成了清淤,計劃年底初見成效,保興垾(九華北路-江堤)、保興垾大富支溝今年開工,計劃11月底完成清淤,明年年底治理完成。浴牛塘計劃2019年治理,市園林處已納入弋江路品質提升一并實施。

板城垾治理 惠及周邊眾多小區

今年以來,鏡湖區整治板城垾水系。通過摸排,在板城垾沿線發現了21個排污口。目前,鏡湖區已阻斷污染源、清理水底淤泥,未來將進行地形整治和岸線整治,讓板城垾水系消除黑臭,改善水環境質量。整治完成后,板城垾周邊的十幾個小區數萬居民將受益。

整治黑臭水體 需要治管并重

民之所望,政之所向,近年來鏡湖區啟動黑臭水體攻堅戰,還綠水與廣大市民。如今,在西洋湖畔,市民們早晨在湖邊晨練,晚上在湖邊散步,這是黑臭水體治理后的一個縮影。盡管在治理黑臭水體上已經取得了一定成績,但鏡湖區住建委工作人員表示,黑臭水體治理是一項長期的系統性工程,表面上是水的問題,實際上關乎城市規劃、基礎設施建設、城市管理等復雜因素,更需要處理好水岸關系、雨污關系、政社關系、治管關系等;三分建七分管,在治好黑臭水體的同時要管得好,要實現水環境持續改善,還須建立長效機制。
