Abstract

The invention discloses a Fenton fluidization wastewater treatment device and a wastewater treatment method thereof. The device includes a water collection pond (8), a pretreatment tower (13), a fluidization reaction tower (1), a post-treatment tower (26), a reagent preparation system (29) and a clear water pond (28). The wastewater treatment method includes the following steps of 1 pretreatment, 2 Fenton fluidization treatment and 3 post-treatment. The wastewater treatment method can reduce the consumption of chemical reagents, the costs can be reduced, and a treatment effect can be improved.

Description

technical field [0001] The invention relates to a waste water treatment device and a waste water treatment method thereof, in particular to a Fenton fluidized waste water treatment device and a method for treating waste water from reconstituted tobacco leaves by using the same. Background technique [0002] Papermaking reconstituted tobacco leaves have low density, high filling value, high silk yield, low tar release, and strong product plasticity, which is one of the important ways for comprehensive utilization of tobacco raw material waste. However, the production process of reconstituted tobacco leaves by the papermaking method consumes a lot of water, and the waste water generated by producing 1 ton of reconstituted tobacco leaves is 70 m 3 above. Papermaking reconstituted tobacco wastewater has high chroma, high content of suspended solids, complex components, and a certain concentration of lignin and other refractory organic matter, so it is very difficult to treat. ...
