System for treating potato chip and potato cake wastewater and process thereof

Abstract

The invention belongs to the field of wastewater, and particularly relates to a treatment system for potato chip and potato cake wastewater and a treatment process thereof, the treatment system for potato chip and potato cake wastewater comprises a water collecting tank, a pretreatment unit, a biochemical treatment unit and a post-treatment unit which are communicated in sequence; wherein the pretreatment unit comprises a grid, a primary sedimentation tank, an oil separation tank, a pH regulating tank, an air floatation tank and a temperature regulating tank which are communicated in sequence;the biochemical treatment unit comprises a UASB reactor, an A2O reaction tank and an MBR tank which are sequentially communicated; and the post-treatment unit comprises a disinfection tank and a clean water tank. According to the scheme, multiple water treatment technologies can be effectively combined and matched with one another to achieve the purposes of efficiently utilizing resources and reducing pollution discharge in potato chip and potato cake wastewater treatment.

Description

technical field [0001] The invention belongs to the field of waste water, and in particular relates to a treatment system and a treatment process for French fries and potato cake waste water. Background technique [0002] Wastewater generated in the basic processing of French fries and potato cakes: Part of the sediment washed during the washing process of raw potatoes is collected and discharged to the sewage treatment system. During the peeling process, starch will be dissolved in clean water and discharged to the treatment system. After being formed into strips, it is blanched at a high temperature of 70-85°C, the cooked starch is dissolved in water and discharged to the sewage treatment system, and a small amount of oil leakage from the oil pan is discharged to the sewage treatment system. The production line production and cleaning process use defoamers and surfactants, etc. Discharge to sewage system. Due to various reasons such as treatment technology, most of the wa...

AI Technical Summary

Problems solved by technology

Due to various reasons such as treatment technology, most of the wastewater is discharged into rivers and lakes without effective treatment, resulting in eutrophication, black odor and other pollution, seriously affecting the environment

[0003] At present, the commonly used wastewater treatment methods of French fries and potato cakes include precipitation method, biochemical treatment method, oxidation method, etc. The treated wastewater cannot meet the increasingly stringent discharge standards, and further optimization and improvement of technology is urgently needed
