摘要:- 當(dāng)前我國許多城鎮(zhèn)污水處理系統(tǒng)仍然面臨著污水收集處理效能低下的問題，如何實(shí)現(xiàn)污水系統(tǒng)提質(zhì)增效已經(jīng)成為行業(yè)研究的焦點(diǎn)。以長江流域典型丘陵城市的實(shí)際案例為基礎(chǔ)，著重探討排水系統(tǒng)效能低下的根本原因和解決方案。提出要在做實(shí)系統(tǒng)排查的基礎(chǔ)上，精準(zhǔn)識別外水匯入點(diǎn)，定量評估外來水入流入滲情況，根據(jù)問題特征及道路管網(wǎng)改造條件“對癥下藥”。以清污分流為突破口，先重點(diǎn)，后全面，制定緩急有序的改造方案，可為山地丘陵城市實(shí)現(xiàn)污水系統(tǒng)提質(zhì)增效提供指導(dǎo)和參考。
Abstract:- At present, many municipal wastewater treatment systems in China are still facing the problem of low efficiency in collection and treatment process. How to improve the quality and efficiency of sewage system has become a research focus. Based on the case study of typical hilly cities in the Yangtze River basin, the root causes and solutions of low efficiency of drainage system are discussed. It is pointed out that the point of extraneous inflow should be accurately identified and its infiltration should be quantitatively evaluated on the basis of thoroughly systematical investigation. Then appropriate strategies should be made according to the features of the problem and conditions of road network reconstruction. Therefore, with water-sewage diversion as a breakthrough, the urgent and orderly reconstruction plan should be conducted in the sequence of focus first and then overall, which can provide guidance and reference for improving quality and efficiency of sewage system in hilly cities.
