摘要:
温州市中心片污水处理厂迁建工程为了节省用地，设计采用半地埋集约化建设模式，污水处理采用曝气沉砂+改良AAO+双层沉淀池+高效沉淀池+滤布滤池+紫外线消毒组合工艺，处理出水水质达到一级A排放标准。该污水厂规模40×104 m3/d，用地面积66 372 m2，采用双层平流沉淀池、构筑物共壁及用渠道连接等集约化设计，用地指标仅为0.166 m2/（m3·d-1），远低于常规污水厂建设用地指标。项目工程费6.26亿元，总投资6.81亿元，吨水造价仅为1 700元，远低于地埋污水处理厂造价，甚至低于地面污水厂。
Abstract:
To save footprint area of a sewage treatment plant migration project in downtown Wenzhou, the intensive semi-buried scheme is designed and applied in the project. The sewage treatment process consists of aerated grit chamber, modified AAO, double-deck sedimentation tank, high-efficient sedimentation tank, cloth media filter and ultraviolet disinfection, and the effluent quality reaches the first level A discharge standard. The treatment capacity and footprint area of the sewage treatment plant are 40×104 m3/d and 66 372 m2, respectively. The intensive design, such as double-deck horizontal sedimentation tank and co-wall and channel connection of the structures, is adopted in the project. The land use index is only 0.166 m2/(m3·d-1) and is far lower than that of the conventional sewage treatment plant. The construction cost of the project is 626 million yuan, the total investment is 681 million yuan, and the cost per ton of water is only 1 700 yuan. The construction cost is far lower than that of the underground sewage treatment plant, even lower than that of the ground sewage treatment plant.
