Paper-making method reconstituted tobacco wastewater deep treatment recycle system and technology

Abstract

A paper-making method reconstituted tobacco wastewater deep treatment recycle system comprises a grating, a primary settling tank, an air floating device, and a first coagulative precipitation tank, wherein the grating, the primary settling tank, the air floating device, and the first coagulative precipitation tank are sequentially connected. The recycle system is characterized in that the first coagulative precipitation tank is sequentially connected with a UASB, an aerobic reaction pool, an MBR, an ozone-aeration biological filter, an ultrafiltration membrane separation device, and a reverse osmosis system, a water generating outlet of the reverse osmosis system is connected with a recycle water pool, a thick water outlet is connected with a Fenton reaction device and a second coagulative precipitation tank, a sludge-tank is further included, a sludge outlet of the air floating device, a sludge outlet of the first coagulative precipitation tank, a sludge outlet of the UASB, a sludge outlet of the MBR, a sludge outlet of the ozone-aeration biological filter, and the second coagulative precipitation tank are connected with the sludge tank, and a gas outlet of the UASB is connected with a gas recovery device. The invention further provides a paper-making method reconstituted tobacco wastewater deep treatment recycle technology. The paper-making method reconstituted tobacco wastewater deep treatment recycle system and the paper-making method reconstituted tobacco wastewater deep treatment recycle technology enable high-density tobacco leaves to be decolored and deodorized, greatly reduce pollutants in the high-density tobacco leaves, ensure that wastewater is recovered for production, and are small in emission amount.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a system and process for advanced treatment and reuse of wastewater from reconstituted tobacco leaves by papermaking. Background technique [0002] The research and industrialization of reconstituted tobacco leaves by papermaking method is earlier in foreign countries, and companies such as Moody and Renault have relatively mature technology and large-scale production. In recent years, the domestic research and application of papermaking reconstituted tobacco has been continuously improved, and factories in Hangzhou, Shantou and Kunming have been built and put into production. At the same time, domestic tobacco factories have also realized the superior characteristics of paper-making reconstituted tobacco, and intend to use it as a new cigarette additive, and have the intention of replacing thick pulp and roller-pressed reconstituted tobacco. [0003] The use of reconstituted...
