Food industry wastewater treatment machine

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a food industry wastewater treatment machine. Comprising a shell, one side of the shell is fixedly connected with a water inlet, a primary filtering mechanism is arranged on the side, close to the water inlet, in the shell, a standing mechanism is arranged on the side, away from the water inlet, of the primary filtering mechanism, a secondary filtering mechanism is arranged on the lower side of the primary filtering mechanism, and a combustion mechanism is arranged on the side, away from the primary filtering mechanism, of the secondary filtering mechanism; the lower portion of the side, away from the water inlet, of the secondary filtering mechanism and the side, facing the combustion mechanism, of the standing mechanism are each provided with a drying mechanism. According to the device, secondary filtration of food industry wastewater can be achieved, water, oil and residues are separated, the oil is burnt to generate heat, a plate for collecting grease is cleaned through the generated heat, the subsequent grease collection efficiency is greatly improved, meanwhile, the heat is used for drying the residues and some collected precipitates, and the heat utilization rate is increased. And the residues are not easy to generate bacteria, so that the subsequent treatment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a food industry wastewater treatment machine Background technique [0002] The food industry has a wide range of raw materials and a wide variety of products. The amount and quality of wastewater discharged vary greatly. The main pollutants in wastewater include solid substances floating in wastewater, and substances suspended in wastewater include oil, protein, starch, colloidal substances, etc. Food Industrial wastewater is characterized by high content of organic matter and suspended matter, easy to be corrupted, and generally has no great toxicity. The main hazard is to eutrophicate the water body, causing the death of aquatic animals and fish, and causing the organic matter deposited on the bottom of the water to produce odor. Deterioration of water quality, pollution of the environment. [0003] Most of the existing treatment of food industry wastewater is dir...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing treatment of food industry wastewater is directly discharged into biofilters or multi-stage biological turntables for biological treatment, but too much suspended matter in wastewater will reduce the treatment efficiency of biofilters, and many solid substances floating in wastewater It cannot be processed by the biological filter, and it needs to be manually cleaned later, or the residue and grease are collected. The plate for collecting grease is often not cleaned, which greatly reduces the efficiency of the subsequent collection of grease. When the residue and some collected sediments are not cleaned. Subsequent processing makes the residue prone to bacteria
