Problems solved by technology

[0006] (2) The sewage contains a large amount of suspended solids, and the fluidity of the settled sludge is not good, so it is necessary to consider the problem of preventing blockage of pipelines and water pumps during sedimentation and sludge discharge;
[0007] (3) The chroma of sewage is relatively high, and targeted removal measures are required

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 Shown is the flow chart of the tobacco wastewater treatment process in the embodiment of the present invention.

[0040] The tobacco wastewater treatment process of the present embodiment comprises the following steps:

[0041] S1. Tobacco comprehensive wastewater is introduced into the grid well for primary filtration. Tobacco comprehensive wastewater includes vacuum moisture resurgence, loose moisture resurgence, expanded tobacco shreds, stem washing, flavoring and feeding process drainage in the tobacco factory's silk workshop, and the cooling cycle including the power workshop. Water system drainage, boiler blowdown, domestic sewage.

[0042] As a common pretreatment equipment, the grille is used in various water treatment occasions. It mainly treats large suspended solids and floating substances in sewage, and pla...

Abstract

The invention relates to tobacco-waste-water processing technology, which comprises grating filtering, mixing and adjustment, agent addition, pressure dissolved-air floatation deslagging, MBR processing, and sterilization. Reclaimed water obtained from MBR processing can be subjected to corresponding treatment according to requirements for being sent to a boiler water supply system, reuse or discharge. The tobacco-waste-water processing technology is designed according to characteristics of pollutants in tobacco waste water. Through the processing technology, the pollutants in the tobacco waste water can be effectively removed and degraded. The reclaimed water obtained from MBR processing is subjected to simple process and can meet requirements of boiler water. A boiler water processing system is greatly simplified, and the tobacco waste water is easily treated to be qualified boiler water. The processing technology has high waste water processing efficiency and automation degree, and is particularly suitable for waste water treatment of a tobacco enterprise.

Description

technical field [0001] The invention relates to a process for treating tobacco wastewater, which belongs to the technical field of industrial wastewater treatment. Background technique [0002] Tobacco wastewater from cigarette factories mainly comes from cigarette production wastewater, office wastewater and domestic sewage (excluding boiler and boiler dedusting wastewater). [0003] The most difficult thing to deal with in the tobacco industry is production wastewater, which has the characteristics of small water volume, high concentration of pollutants, complex components, large changes in water quality, high chroma, and irregular discharge. The main source of this type of wastewater is: the water used for expanding shredded tobacco and washing stems in the first half of the tobacco production process, the water volume is small, the concentration of pollutants is high, the alkaloids and phenols in the oily tobacco leaves, etc. ℃; the white glue wastewater in the middle s...
