江苏某化工园污水处理厂提标改造设计

Upgrade Design of Sewage Treatment Plant of A Chemical Park in Jiangsu Province

为了响应苏政办提出的提标改造要求,对江苏某化工园污水处理厂进行提标改造设计。改造思路为新增臭氧预处理单元处理农药类企业排水,科学合理地结合一期、二期现有建构筑物,改造/利旧预处理单元、生化处理单元和深度处理单元,增设活性碳吸附深度处理单元,确保出水各指标达标排放。经过了一年多的运行,污水处理厂进水水质满足设计进水水质要求,出水水质连续稳定达到《城镇污水处理厂污染物排放标准》(GB18918-2002)表1一级A排放标准,持续改善园区河道及相关海域的水环境,减轻了企业污水处理负担,增强了园区招商引资的吸引力,提高了附近居民的生活质量,也为类似化工园污水处理厂的改造提供一定参考。

In response to the requirements of upgrading and reconstruction proposed by the Soviet political office,the upgrading and reconstruction design of a sewage treatment plant in the chemical park in Jiangsu was carried out.The renovation idea is to add a new ozone pretreatment unit to treat pesticide class enterprise drainage,scientifically and reasonably combine the existing buildings and structures in Phase I and Phase II,renovate/leverage the old pretreatment unit,biochemical treatment unit and depth treatment unit,and add an activated carbon adsorption depth treatment unit to ensure that the effluent indicators meet the discharge standards.After more than one year of operation,the inlet water quality of the sewage treatment plant meets the design inlet water quality requirements,and the outlet water quality continuously and stably meets the first level criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).This process continuously improved the water environment of the river channel and relevant sea areas in the park,reduced the burden of enterprise sewage treatment,and enhanced the attraction of attracting investment in the park.It not only improves the quality of life of nearby residents but also provides a reference for transforming sewage treatment plants in similar chemical parks.
