Rice milk water zero discharge recycling system

Abstract

The invention relates to a zero-discharge recycling system of rice milk. The system comprises a stainless steel movable water saving car, a high level rice milk storing tank and stainless steel sterilization tanks, wherein a drain pipe is arranged on the stainless steel movable water saving car and connected with a delivery pump at one side of the car; a delivery hose is arranged on the delivery pump and connected with a high level water feeding pipe arranged on the top of the high level rice milk storing tank; a pipeline is arranged at the bottom of the high level rice milk storing tank and connected with the tops of the stainless steel sterilization tanks respectively. The system disclosed by the invention has the beneficial effects that the unreasonable state that the rice milk is treated as sewage to be discharged is changed and the collected rice milk is put into the yellow wine brewing process again after being subjected to heating and sterilization, so that the traditional brewing production process is changed, the labour intensity of workers is reduced, the production environment is changed, the primary pollution source in the yellow wine production is reduced, the water resource is saved, the production source utilizing ratio is increased by using the rick milk and the sewage discharging quantity of the brewing is reduced.

Description

technical field [0001] The invention relates to a rice milk water zero-discharge recycling system, which belongs to the technical field of rice wine brewing. Background technique [0002] In the traditional rice wine brewing process, the glutinous rice needs to be soaked for a period of time, and the next rice steaming process can be carried out after the rice is loose. Therefore, the rice soaking process consumes a lot of water and produces high COD and total acid content. Rice milk water, these rice milk water is generally treated as sewage and directly enters the sewage tank for treatment. And along with the expansion of yellow rice wine industry, the output of rice milk water also increases year by year. If the idea of ​​sewage treatment is still used to treat rice milk water, such as acidification, UASB anaerobic, SBR aerobic and other combined treatment processes, the treatment cost and equipment investment will remain high. The rice milk water is very rich in nutrie...

Problems solved by technology

If the idea of ​​sewage treatment is still used to treat rice milk water, such as acidification, UASB anaerobic, SBR aerobic and other combined treatment processes, the treatment cost and equipment investment will remain high

The rice milk water is very rich in nutrients, containing a large amount of organic acids, amino acids, proteins, starches, sugars, fats, vitamins, etc. If it cannot be effectively used, it will also be a great waste, and it will be discharged directly into the river. It will cause eutrophication in the river water and damage the biological chain, which will have a great impact on the environment
