Description

[0001] The present invention relates to a treatment device for tobacco sheet production wastewater, in particular to a treatment device for tobacco sheet production wastewater and tobacco production wastewater based on chemical decalcification technology, biochemical technology, electrochemical technology and MBR technology, which belongs to environmental engineering in the field of water pollution control. 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 cigarettes, 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 debris, tobacco sheet technology came into being. Tobacco sheet, also known as reconstituted tobacc...
