Abstract

The invention relates to a treatment and regenerative cyclic utilization device for tobacco sheet production wastewater. The treatment and regenerative cyclic utilization device comprises a mechanical coarse-grille water collecting basin, a rotary fine-grille machine, a regulation pool, a primary decalcification reaction pool, a secondary decalcification reaction pool, a primary sedimentation tank, a filtering device, a coagulation tank, an air flotation tank, a UASB (Upflow Anaerobic Sludge Blanket) anaerobic tank, an electrolyzer a, an anaerobic pool, an aerobic pool, a secondary sedimentation tank, an electrolyzer b, a membrane treatment device or biological aerated filter, an electrolyzer c, a water supply pump, a desalting device, a reclaimed water storage tank, a sludge tank, a sludge dewatering device, an accident pool, a gas collection device and a marsh gas storage tank. The treatment and regenerative cyclic utilization device has the advantages that on the basis that chemical decalcification techniques, biochemical techniques, electrochemical techniques, BAF (Biological Aerated Filter) techniques and membrane technologies are combined, the cost is lower, and the efficiency is higher; after the tobacco sheet production wastewater is treated, 75-85% of the tobacco sheet production wastewater can be utilized in a regenerative and cyclic manner, so that the discharge of the wastewater is reduced, the environmental pollution caused by the wastewater is avoided, and the waste of water resources is reduced; and the cost of reclaimed recycled water can be lower than the price of tap water, so that the reclaimed recycled water is economical and reasonable, and a better economic benefit is generated.

Description

technical field [0001] The present invention relates to a treatment and recycling device for waste water from tobacco flake production, in particular to a waste water from tobacco flake production and tobacco production waste water based on chemical decalcification technology, biochemical technology, electrochemical technology, BAF technology and membrane technology The treatment and regeneration recycling device belongs to the field of water pollution control of environmental engineering. Background technique [0002] During the production of tobacco leaves, the raw materials cannot be fully utilized. During the production process of tobacco from primary processing to cigarette production, there will be scraps accounting for about 1 / 3 of the total amount of raw tobacco materials. These tobacco scraps cannot be directly used as The raw material is again made into a cigarette product. In order to reduce the generation of waste and realize the comprehensive utilization of de...
