金湾区河长制年内“区镇村组”全覆盖

2017-08-10 12:38:52   中国青年网

区别于城镇河涌治理中采取的硬底化改造等措施,农村地区的水环境综合整治,将尽量保持原有生态和景观。为此,金湾区提出要因地制宜地连通小林片区、大林片区等水系,加速推进重点流域水环境整治和水生态修复工程。通过湿地公园建设等工程,提升生态环境质量景观。在磨刀门、鸡啼门等主要入海河道,也将以修复红树林湿地为重点,构建平安生态绿色水网。

三灶水质净化厂年底完成升级

随着城镇人口和企业数量的增长,城市污水处理系统的升级也被提上了日程。记者获悉,正在改造的三灶水质净化厂推进顺利,预计今年12月可建成通水,污水处理能力增加一倍有余。另外,金湾区第二水质净化厂也正在选址当中。

“三灶城区的污水经过市政管网的截流后统一输送到三灶水质净化厂进行处理,而该厂的设计处理能力为日均3万吨,随着城镇规模的扩大,已难以满足当前的需求。”吴耀东介绍。

据了解,总投资1.47亿元的三灶水质净化厂提标改造及改建工程目前已完成形象进度的10%,计划在今年12月建成通水。吴耀东表示,“新建工程投入使用后,日处理污水可达5万吨,较此前增加一倍多。”

另外,金湾还拟新建金湾区第二水质净化厂,目前正处于选址阶段。新厂的建设将主要针对红旗镇以及航空新城片区未来居民生活污水处理,按照计划日处理污水量能力将在10万吨以上,建成后将成为金湾区规模最大的水质净化厂。
