Problems solved by technology
[0003] Fermentation wastewater contains a lot of calcium and magnesium ions. During the separation of living membranes, it is easy to cause frequent clogging of the membrane. If it is necessary to remove the clogging, it is necessary to stop the operation of the equipment and clean the clogging by cleaning the membrane. Such treatment The method will affect the efficiency and progress of fermentation wastewater treatment. If the membrane is not deblocked in time, it will affect the effluent index, resulting in poor treatment effect of fermentation wastewater

The invention discloses multistage membrane separation equipment for treating and recycling fermentation wastewater structurally comprising a metal impurity primary treatment device, a supporting seat, a damping base, a multi-stage biological membrane separation equipment body and supporting legs; the supporting legs are vertically connected to the bottom of the multi-stage biological membrane separation equipment body; the damping base is arranged on one side of the multi-stage biological membrane separation equipment body. Compared with the prior art, the beneficial effects are that: a sliderheostat, an electromagnet group, a U-shaped pipe, a fixed cover, a movable cover and other parts are combined; before the fermentation wastewater is introduced into a biological membrane for separation, based on a communicating vessel principle and a magnetism principle, metal impurities such as calcium and magnesium ions can be collected, the membrane is prevented from being blocked due to themetal impurities, the condition that the membrane is frequently blocked is avoided, the treatment efficiency and progress of the fermentation wastewater are improved, time and labor are saved, and thetreatment effect of the fermentation wastewater can be improved.
Description
technical field [0001] The invention relates to the technical field of biofilm separation, in particular to a multi-stage membrane separation device used for the treatment and reuse of fermented wastewater. Background technique [0002] The fermentation industry is a processing industry with grain and agricultural by-products as the main raw materials. It mainly includes alcohol, monosodium glutamate, starch, liquor, citric acid, starch sugar and other industries. As far as my country's national conditions are concerned, the deep processing and industrialization of crops and economic crops is the core means to promote the sustainable development of agricultural economy, increase farmers' income, improve the gap between urban and rural areas, and realize the balanced development of the national economy. However, due to the large water consumption of the fermentation industry and the serious pollution of wastewater discharge, the sustainable development of the fermentation in...
