Abstract

The invention relates to a reclaimed water recycling device of reconstituted tobacco wastewater and a technology thereof. The device is characterized by comprising a biochemical treatment system and an advanced treatment system. The biochemical treatment system comprises a water collecting well, a rotary filter screen, an adjusting tank, a coagulating basin, a primary sedimentation tank, a regulating pre-acidification tank, a circulating pool, an anaerobic pond, an aerobic tank and a secondary sedimentation tank. The advanced treatment system comprises a membrane bioreactor (MBR), a reverse osmosis system (RO), a nanofiltration system (NF) and a membrane chemical reactor (TMR). An effluent from the secondary sedimentation tank of the biochemical treatment system firstly passes through themembrane bioreactor for mud-water separation, and then produced water enters the reverse osmosis system to be treated for recycling. Concentrated water enters the nanofiltration system to be treated,and the produced water is directly discharged. A polymeric flocculant is added into the concentrated water and the concentrated water passes through the membrane chemical reactor, COD is greatly reduced; and then the concentrated water is uniformly mixed with the produced water from the nanofiltration system, thus achieving up-to-standard discharge. When the concentrated water in the membrane chemical reactor reaches a certain solid content, the concentrated water is intermittently discharged into a sludge thickener.

Description

Technical field [0001] The invention relates to a device and process for reusing water in reconstituted tobacco waste water, and is suitable for the technical field of waste water biological treatment in the process of reconstituted tobacco production. Background technique [0002] Waste water mainly comes from the reconstituted tobacco production workshop, which is produced during the extraction of tobacco raw material extracts, fiber papermaking, and equipment washing. It is mainly divided into high-concentration wastewater and low-concentration wastewater. High-concentration wastewater includes: tobacco raw material extrusion liquid, extract liquid wastewater, cleaning wastewater from extraction tanks, formula tanks and concentrated liquid storage tanks; low-concentration wastewater includes most equipment cleaning wastewater, water extract condensate wastewater, and papermaking department Thin white water and thick white water for pulping and papermaking. There are two main ...
