Abstract

The invention relates to a method and a device for treating and recycling tobacco wastewater with a double-membrane process. The main processes comprise an intelligent efficient flotation process, an MBR process, an advanced oxidation process and a RO process. The device mainly comprises a grating, a regulation pool, an intelligent efficient flotation system, an MBR system, an advanced oxidation system and a RO system. The intelligent efficient flotation process adopts a fuzzy control algorithm for real-time regulation of the feeding amount of flocculant according to the influent quality; thewater discharged in the MBR process can be directly used for green flushing or can flow into the RO system for advanced treatment after advance oxidation, and the water discharged in the RO process can be used as water supplied to a boiler or as circulating cooling water of an air conditioner. The invention has the advantages that the treatment and recycling of tobacco wastewater is realized through the double-membrane process, the equipment is compact, the degree of automation is high, the operation is simple, and the effluent quality is excellent and stable.

Description

technical field [0001] The present invention relates to a method and device for treating and reusing tobacco waste water by a double-membrane method, in particular to a method for treating tobacco waste water and meeting the reuse standard by adopting a combined process of intelligent high-efficiency air flotation + MBR + advanced oxidation + RO and The device belongs to the field of waste water treatment and reuse. Background technique [0002] With the rapid development of my country's economy, the consumption of water resources has doubled. On the one hand, it has caused a shortage of water resources. The continuous improvement of water quality discharge standards has prompted more and more enterprises to raise the standard of sewage discharge or reuse to a very high position from the perspective of economic and social benefits. [0003] Domestic cigarette factories seldom carry out comprehensive and comprehensive treatment of the wastewater of the whole factory, and mos...
