Problems solved by technology

[0003] The treatment of papermaking wastewater has always been an important part of environmental protection projects, but for a long time, the treatment of papermaking wastewater requires multiple processes, multiple equipment, and multiple hours of centralized operations to complete the purification. Multiple equipment not only greatly increases the cost of wastewater treatment, It also increases the floor area of ​​the treatment equipment, which virtually increases the cost of the wastewater treatment factory

Abstract

The invention relates to the technical field of sewage treatment, specifically to a filtering device for recovering wastewater of a papermaking enterprise. The filtering device comprises a wastewatercollection box, wherein two sides of the wastewater collection tank are respectively provided with a moving driving unit and a moving driven unit which are respectively arranged on the side walls of two ends of the wastewater collection box through two groups of fixed units; a supporting cross beam is arranged between the moving driving unit and the moving driven unit; a walking filtering unit isarranged on the supporting cross beam; one end of the wastewater collection box is connected with a wastewater outlet pipe through a pipeline; the other end of the wastewater collection box is connected with a cyclic utilization pipeline through a pipeline; and the interior of the wastewater collection box is also provided with a group of sediment treating units. According to the invention, centralized treatment of sewage is completed through a device, so the occupied land area of sewage treatment equipment is greatly reduced, and the treatment cost of a sewage treatment plant is reduced.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a suspended matter filtering device used for recycling waste water in enterprises. Background technique [0002] Papermaking wastewater refers to the wastewater generated during the pulping and papermaking process. Including pulping and cooking waste liquid, washing waste water, bleaching waste water and paper machine white water, etc. Papermaking wastewater has complex components and poor biochemical properties. It is difficult to treat industrial wastewater and is one of the main sources of industrial pollution. At present, the papermaking industry mostly uses straw and wood pulp as papermaking raw materials. Pulping and papermaking production generally consists of pulping, pulp washing, bleaching, and papermaking processes. Pulping in the paper industry includes alkaline pulping, chemical mechanical pulping and mechanical pulping. According to different pulpin...
