Abstract: In the river pollution control, the waterfront sewage outlet is an important aspect that leads to polluted and even smelly water. In reality, it is faced with many restrictive factors, such as construction space, construction time, investment, operation and maintenance costs, etc., In order to solve this problem, this paper puts forward a "decentralized collection, on-the-spot disposal and resource utilization" system scheme, in order to achieve fast, effective and low-cost pollution interception and elimination of pollution sources, bring new irrigation water resources for the new riverside greening space, and solve the economic problem of long-term operation and maintenance after the completion of the system.

Keywords: riverside sewage outlet treatment; gravity flow pollution interception; negative pressure system; decentralized collection, on-the-spot disposal and resource utilization

1 背景

在河道污染治理中滨水排污口是导致水体污染甚至黑臭的重要方面,对直排污水有效地截污、治理,并进一步实现污水净化处理后作为非传统水资源加以利用是治理过程中的基本需求和目标。本文以某河道污染治理项目为例,对此开展解决方案分析。

该河道流域的上游以山林、农田、村镇为主,下游为相对平坦的城区段,项目实施治理范围内基本为城市待开发建设区,内部分布有大量的村莊,村庄污水均沿现状合流制排水渠道汇集并进入该河道内,带来了较为严重的污染,导致水体呈劣Ⅴ类水质。

在项目建设之初,从全流域角度,将对河道水体带来严重污染的农田面源污染、养殖废水排入污染以及集中城镇直排污水污染、河道内源污染等分别采取有效管控措施,形成系统治理,分段控制的总体策略。而针对城市待开发建设区滨河沿线的众多排污口的污染治理成为了城区段污染治理的重点。……
