摘要
茅洲河是珠三角区域污染最严重的河流,底泥污染是茅洲河全流域黑臭的主要原因之一。为了消除黑臭,提升茅洲河水质、改善生态环境,本文采用“环保绞吸式挖泥船+输泥管输送”方案,配套设置底泥处理厂,采用板框压滤机对底泥进行脱水固化,对余水采用超磁净化技术进行处理。清淤后,茅洲河国考断面提前一年两个月达到国考目标,治理效果显著,其治理经验可为类似工程提供借鉴。
Maozhou River is the most polluted river in the Pearl River Delta region,and sediment pollution is one of the main causes of black odor in the whole basin of Maozhou River.In order to eliminate the black odor and improve the ecological environment of Maozhou River water quality,this paper adopts the scheme of“environmental protection cutter suction dredger+mud pipe transportation”,sets up a sediment treatment plant,dewaters and solidifies the sediment with a plate and frame filter press,and treats the residual water with super-magnetic purification technology.After dredging,the national examination section of Maozhou River reached the national examination goal one year and two months ahead of schedule,and the treatment effect was remarkable.Its treatment experience can provide reference for similar projects.
