Environment-friendly water treatment equipment for processing industry

Abstract

The invention relates to the technical field of sewage treatment, in particular to environment-friendly water treatment equipment for the processing industry. The equipment comprises a barrel, a trash cleaning disc is rotatably mounted on the inner side of the barrel, a notch is formed in the inclined upper part of the barrel and corresponds to the front of the trash cleaning disc, a cleaning disc is rotatably mounted on the inner side of the notch, and a flow dividing structure is arranged on the inner wall of the barrel corresponding to the front lower part of the notch. A cleaning area and a stabilizing area are respectively formed on the surface of the cleaning disc corresponding to the rear parts of the cleaning disc and the flow dividing structure, a sinking matter accumulation area is formed on the surface of the cleaning disc close to the lower end edge, and a floccule accumulation area is formed on the surface of the cleaning disc except the cleaning area, the stabilizing area and the sinking matter accumulation area. Sewage flowing backwards from the inner side of the barrel leads floccules to the floccule accumulation area and leads sinking impurities to the sinking matter accumulation area through the flow dividing structure. According to the invention, sewage containing floccules and sinking matters in fruit and vegetable processing can be effectively treated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environmental protection device for water treatment used in the processing industry. Background technique [0002] Fruit and vegetable processing is the purpose of long-term preservation, durability and ready access through various processing techniques. With the development of the food industry, fruit and vegetable processing plants are widely covered. For the processing of fruits and vegetables with more roots such as corn, Sewage contains rhizome flocs in fruits and vegetables and impurities that are easy to sink. These two kinds of impurities have great problems in sewage treatment. In the prior art, they are treated by means of filters, and flocs accumulate on the surface of the filter. When too much, it is easy to block, and the sinking impurities are removed through an additional precipitation process, which is not cumbersome. Therefore, the environmental prote...

Problems solved by technology

[0002] Fruit and vegetable processing is to use various processing techniques to make fruits and vegetables achieve long-term storage, durability, and ready-to-use purposes. With the development of the food industry, fruit and vegetable processing plants are widely covered. For the processing of fruits and vegetables with more roots and tubers such as corn, Sewage contains rhizome flocs in fruits and vegetables and impurities that are easy to sink. These two impurities are a big problem in sewage treatment. In the prior art, they are treated by filter screens, and the flocs accumulate on the surface of the filter screen. When it is too much, it is easy to block, and the sinking impurities are removed through an additional sedimentation process, which is cumbersome and difficult. Therefore, the environmental protection equipment in the prior art has a very poor treatment effect on the sewage containing rhizome flocs and sinking impurities in fruit and vegetable processing plants.
