摘要
某焚烧厂水处理主要分为纯水处理和污水处理.针对纯水处理设计采用"活性炭过滤器+超滤+反渗透+EDI"工艺,纯水处理后作为生产用水进行回用.处理的污水主要包括无机废水和有机废水,污水成分复杂、含有大量重金属,设计无机废水通过"一体化沉淀装置(pH调节池+混凝池+絮凝池+沉淀池)"处理去除废水中重金属后,进入生化进水均质池;有机废水直接进入生化进水均质池,废水通过均质均量后采用"生物接触氧化池+二沉池+中间水池+多介质过滤器+滤后水池+回用水池"工艺.综上,对于该行业水处理,使用组合工艺处理效果好、投资和运行成本较低,既达到厂内节水用水要求,又实现了废水处理的资源化利用.
Abstract
An incineration plant water treatment is mainly divided into pure water treatment and wastewater treatment.For pure water treatment design using"activated carbon filter + ultrafiltration + reverse osmosis + EDI"process,pure water is treated and reused as production water.The treated wastewater mainly includes inorganic wastewater and organic wastewater,and the composition of wastewater is complex and contains a large number of heavy metals,so the inorganic wastewater is designed to remove heavy metals from the wastewater through the treatment of"integrated sedimentation device(pH adjusting tank + coagulation tank + flocculation tank + sedimentation tank)",and then enters into biochemical inlet homogenization tank;the organic wastewater enters the biochemical inlet homogenizer tank directly,and after the wastewater is homogenized,adopts the process of"biological contact oxidation tank + secondary sedimentation tank + intermediate pool + multi-media filter + post-filtration pool + reuse pool".In summary,for the industry water treatment,the combination process has good treatment effect and low investment and operation cost.It not only meets the requirements of saving water in the plant,but also realizes the resource utilization of wastewater treatment.
