Background
The Maotai-flavor liquor is one of Chinese traditional flavor liquor, has a long history, and in the process of producing the Maotai-flavor liquor, in order to promote the compound flavor of the liquor, base liquor with different rounds, different typical bodies, different alcohol degrees and different ages is combined according to a certain proportion, so that the blended liquor meets the standard of finished liquor, and in the process of brewing, special pit bottom water is added into the fermented grains for fermentation, so that special flavor is increased, the pit bottom water is liquid permeated to the bottom of a pit in the process of fermenting and brewing the Maotai-flavor liquor, and the components are extremely complex, contain a large amount of alcohol, aldehyde, acid and fat generated by fermentation, sugar, protein which are not completely fermented, yeast microorganism which is specially domesticated and the like.
In the actual production process, the bottom of the pit is generally of a mud structure, when external factors such as ambient temperature, humidity, groundwater level, water quality and the like change, water in the external environment permeates into the pit bottom, or technical process water seeps out of the pit bottom, meanwhile, in different fermentation stages, the fermentation process is different, so that the change of the water quantity, the water quality and the like of the pit bottom is relatively large, water is inevitably produced in the fermentation process, the pit bottom water cannot be fully recycled basically, when the pit bottom water is excessive, the pit bottom water cannot be fully recycled to the fermentation process, the organic matter content in the pit bottom water is very high (generally COD reaches more than 150000 mg/L), the risk of environmental pollution is caused, the resource waste is also caused, in addition, the pit bottom water also contains a large amount of low-boiling-point fusel, and the flavor of finished wine is also influenced if the fusel enters the fermentation process, so that the pit bottom water is required to be concentrated and the concentration and the property of beneficial organic matters in the concentrated solution are ensured to be fully recycled, and on the other hand, the water quality of the pit bottom water is reduced and the water is further reduced as low as possible after the fusel is removed.
At present, the waste pit water is mainly treated by adopting an anaerobic biological method, which is a process technology for treating the pit water as waste water, the anaerobic biological treatment refers to a process of decomposing and converting various complex organic matters in the waste water into substances such as methane, carbon dioxide and the like under the condition of no molecular oxygen by using anaerobic microorganisms (including facultative microorganisms), and the anaerobic biological method can solve the problem of environmental risk brought by the pit water and generate a certain amount of methane (can be used as fuel gas), but the method cannot effectively utilize various organic matters in the pit water, cannot be recycled into a fermentation process and is not a route for maximizing resource benefit. However, the membrane technology has the problem of easy fouling and blocking for wastewater with higher organic matter content. In addition, the film separation technology can only intercept part of organic matters at present, has no selective separation effect on the pit bottom water containing complex organic matters, and in addition, a large amount of defoamers and cleaning agents are needed to be added in the film separation process, so that pollutants can be brought to the concentrated pit bottom water to influence the subsequent recycling.
