赶潮河涌污染修复的对策研究——以东莞市蚬涌河为例

Study on Countermeasure for Pollution Repairing of Tide River——Taking Xianchong River of Dongguan as an Example

通过对东莞市蚬涌河水体的水质分析,获得了河水水体的水文资料和水体污染特征;发现造成河水污染的主要原因是:工业废水排污地域分布分散,行业分布广泛,排放总量逐年增加,大量未经处理的城镇污水的直接排放以及河网地区潮流的顶托作用,使该地区部分河段水质恶化,进而影响到水源地水质。针对上述污染问题,提出了赶潮河水污染综合治理对策。

An investigation was carried out on pollution situation of Xianchong River of Dongguaa City in Guangdong Province. The results were： industrial waste water tended to be more widely distributed in regions and professions, total amount of industrial waste water and domestic sewage discharging was increased every year, in addition with the direct discharging of untreated city sewage and the tidal effects, which caused water pollution problems in the area. Some measures of the pollution repairing were provided in this paper.
