分析了“三泥”装置运行现状,针对“三泥”在储存罐、浓缩罐、预处理系统、离心机的脱水技术进行了研究;提出了对离心脱水机出口脱油线、脱液线、配药系统、离心脱水机“堰板”问题进行改进。采用在浓缩罐底部出泥线前加阀,使浓缩罐底部能脱水,解决污泥在预处理系统含水率高的问题;采用在搅拌池底部出泥线阀前加阀,解决污泥上离心机前含水率高的问题。重新利用调节隔油池对污泥脱水,把握滤液回到污水处理场浮选池水质质量。解决了污泥处理效率低、污泥脱水困难、泥饼含水率高、自动化程度低等问题。
The operation status of the “three mud” device was analyzed and the dehydration technology of “three muds” in the storage tank, the concentration tank, the pretreatment system and the centrifuge was researched. The deinking line of centrifugal dewatering machine was put forward, Drip line, dispensing system, centrifugal dryer “Bar ” problem to be improved. Adopt the valve at the bottom of the enrichment tank before the mud line, so that the bottom of the concentrating tank can be dewatered to solve the problem of high moisture content of the sludge in the pretreatment system; the valve is added before the mud line valve at the bottom of the mixing tank to solve the problem that the sludge is centrifuged Pre-machine moisture content of the problem. Re-use of the grease trap to adjust the sludge dewatering, grasp the filtrate returned to the sewage treatment pond flotation pool water quality. The invention solves the problems of low sludge treatment efficiency, difficult sludge dewatering, high cake moisture content and low degree of automation.
