Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-source sludge treatment, and particularly relates to an equipment and method for discriminating sampling of multi-source sludge. BACKGROUND

[0002] In addition to the hazardous waste list, sludge suspected to contain toxic and harmful substances needs to be identified as hazardous waste. According to the "mixed judgment rule" and "utilization disposal judgment rule" specified in the "General Standard for Hazardous Waste Identification" (GB 5085.7), the hazardous waste identification object should be accurately identified. The wastewater treatment sludge is a solid waste generated in the process of environmental governance and pollution control. The "Technical Specification for Hazardous Waste Identification" (HJ 298-2019) stipulates that such solid waste "should be sampled during the stable production period of the pollution control facility pollutant source, facility operation load and effect; and the solid waste generated in different process links should be sampled respectively according to the environmental governance and pollution control process".

[0003] Wastewater treatment sludge can be roughly divided into domestic wastewater sludge and industrial wastewater sludge according to its source. According to the wastewater treatment method, the degree of sludge separation from wastewater or the sludge generation stage, the sludge can also be divided into different types. The organic matter, heavy metals and other harmful substances in the sludge generated in different process links are quite different, so it is necessary to sample the filter pressing sludge generated in different process links during the hazardous characteristic identification process. However, the existing wastewater treatment enterprises often have only one thickening tank or a set of plate and frame filter press, which cannot realize the classification collection, filter pressing and sampling of sludge.

[0004] In the prior art, the sludge pipeline entering the plate and frame filter press needs to be changed to classify and sample the sludge in different process links. However, changing the sludge pipeline and then filter pressing the sludge is relatively cumbersome, which not only affects the normal operation of the overall process, but also causes the sludge in different pipelines to contaminate each other, affecting the accuracy of hazardous characteristic identification. At the same time, the production amount of part of the sludge is small, and it needs to be operated for a long time to meet the starting conditions of the plate and frame filter press, which affects the normal production of sludge and sampling in other process links.
