The waste water processing technology features that the waste water is first coagulation and air floatation treated to eliminate suspended solid, and then aerobic microbe treated in aeration pond to eliminate most COD matter, so as to make the waste water produced in the paper-making simulating tobacco sheet producing process reach the exhaust standard. The dregs and the sludge the waste water processing course produces may be used as fertilizer for crop or fuel for boiler. The present invention has low processing cost and no secondary pollution.
Description
technical field [0001] The invention relates to waste water treatment of tobacco flakes in papermaking, and belongs to the technical field of tobacco processing industry and clean production. technical background [0002] Tobacco sheet by papermaking method is a high-tech technology for recycling tobacco waste in the tobacco processing industry. The product has many incomparable characteristics of natural tobacco, such as low cost, low density, high filling value, low tar release, adjustable chemical composition, etc. Therefore, paper-making tobacco sheets are usually used as important raw materials for cigarette leaf formulations and cigarettes. It is an important tool for reducing coke and consumption of products. Chinese authorized patent CN1033359, Chinese patent application publication CN1322498, CN1370475 all relate to papermaking method tobacco flake production technology. [0003] The production of paper-making tobacco flakes follows the papermaking process and che...
