摘要 中堂镇位于东莞市西北部，水污染主要由排水体制混乱、污水收集系统不完善、水体污染严重等造成，亟需提升流域水体质量，改善环境。以东向鹤田流域为调查对象，对水环境状况开展了排污口、污水管网和水污染成因研究和调查，分析了水污染现状及成因。针对流域水环境存在的问题，设计内源治理、活水保质、河岸整治等治理措施。设计方案实施后，东向鹤田涌水质指标基本达到不黑不臭，水质力争达到V类水。

Abstract Zhongtang Town is located in the northwest of Dongguan City. The water pollution is mainly caused by disordered drainage system， imperfect sewage collection system and serious water pollution， so it is urgent to improve the water quality of the basin and improve the environment. East-facing Tsurtianchong drainage basin is the research object， and the water environment conditions of sewage outlet， sewage network and water pollution causes were studied and investigated， and the current situation and causes of water pollution were analyzed.Aiming at the problems existing in the water environment of the drainage basin， measures are designed， such as endogenous management， fresh water quality preservation， river regulation and so on.After the implementation of the designing scheme， the water quality index of the East-facing Tsurtianchong drainage basin basically reaches neither black nor odorous， and the water quality strives to reach V class water.

随着我国经济社会高速发展和人口增加，我国河道生态需水得不到满足，河流污染日趋严重，水环境持续恶化，限制了城市经济和社会发展[1-2]。日益恶化的水污染趋势，不同程度地使城市居民生活环境受到损害，危害了流域人民身体健康，制约流域的可持续发展[3]。水环境对城市发展来说至关重要，有必要采取有效的措施对城市水环境进行修复和治理[4]。目前，国内外在河道污染的治理方面主要集中在生态改造[5]、生态修复[6-7]、截污[8]、面源污染的控制[9]、补水等方面，水乡片区流域综合整治的成功案例较少。

研究以东莞市中堂镇东向鹤田涌流域为调查对象，近年来，东向鹤田涌流域范围内水体污染严重，严重影响河道景观，甚至危及周边居民的健康安全。流域水环境及水景观治理关乎东江下游水质，为响应广东省环境保护督查和东莞市水污染治理攻坚战的工作布局，亟需开展流域污染现状调查和综合整治。……
