摘要
以某焦化企业工业污水处理厂为例,通过对焦化废水涉及的生产工艺、原辅材料、废水量、污泥产生情况的分析,对板框压滤机产生的物化污泥可能具有的危险特性进行了筛选,确定了物化污泥危险特性鉴别的检测项目和样品数量,根据检测结果对物化污泥的危险特性进行判定,分析焦化行业废水零排放及资源化前景,提出陶粒窑协同处置物化资源化利用建议,为同类型污水处理厂污泥危险特性鉴别工作提供参考。
Taking an industrial sewage treatment plant of a coking enterprise as an example, through the analysis of the production process, raw and auxiliary materials, wastewater volume and sludge production involved in the coking wastewater, the possible dangerous characteristics of the physical-chemical sludge produced by the plate and frame filter press are screened, and the detection items and the number of samples for the identification of the hazardous characteristics of the physical-chemical sludge are determined. According to the test results, the hazardous characteristics of the physical-chemical sludge are determined. This paper analyzes the zero discharge and resource utilization prospect of coking wastewater, and then the suggestion on the resource utilization of the physical-chemical sludge in the co-processing of Ceramsite Kilnis put forward, which provides a reference for the identification of hazardous characteristics of sludge in the same sewage treatment plant.
