Food processing Wastewater Machinery

Product Description

There are many kinds of raw materials in food factories, such as fruits, vegetables, meat, seafood, etc. General food factory sewage contains some solid substances suspended in the sewage.
1. Vegetable leaves produced by processed vegetable products, processed fruits will produce peels, a piece of minced meat, animal feathers, etc.;
2. Suspended substances have a certain amount of oil, protein, starch, gelatinous objects, etc.;
3. There will be mud and sand in some raw materials, as well as acids, salts, sugars, alkalis, etc. that are dissolved in sewage;
Food factory sewage treatment equipment has complete models. 4. Food factory sewage is a type of industrial sewage. The general sewage is characterized by high organic matter content and high suspended matter content. It is not easy to store and easy to rot. Although it is not too toxic, it contains Pathogenic bacteria, etc. If this kind of sewage is discharged directly into the river without treatment, it will cause the extinction of fish and shrimp and other aquatic organisms, make the organic matter deposited at the bottom of the water produce foul smell, deteriorate the water quality, and cause serious pollution to the environment. For sewage treatment in food plants, physical pretreatment methods can be selected according to the characteristics of water quality, and more biological processes are used.
After the sewage is treated by the biological contact oxidation tank, the effluent flows into the secondary sedimentation tank to further precipitate and remove the fallen biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity. When the sewage containing suspended solids flows from the bottom to the bottom When it flows upward, the substance is precipitated by gravity. The effluent after sedimentation in the secondary settling tank is more clear and transparent. The secondary sedimentation tank is a vertical flow sedimentation tank, and the sludge pump is used to regularly lift the sludge into the sludge digestion tank. The treated water after precipitation enters the subsequent treatment equipment.
Food sewage treatment equipment process:
1. Because the biological touch oxidation tank is selected in the AO biological treatment process, the volume load of the filler is relatively low, and the microorganisms are in the self-oxidation stage, so the amount of mud produced is small. In addition, the moisture content of the sludge generated in the biological touch oxidation tank is much lower than the moisture content of the sludge generated in the activated sludge tank.
2. The AO biological treatment process in the sewage treatment equipment selects the push-flow biological touch oxidation tank, and its treatment is better than the thorough mixing type or the two or three-stage series series thorough mixing type biological touch oxidation tank. Moreover, it has a smaller volume than an activated sludge tank, strong adaptability to water quality, good impact resistance, stable effluent quality, and no sludge swelling.
3. Food sewage treatment price. After the sewage is treated by the biological contact oxidation tank, the effluent flows into the secondary sedimentation tank to further precipitate and remove the fallen biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity effect. When the sewage with suspended solids moves from bottom to top, the material will be precipitated by the effect of gravity.
Equipment process characteristics
1. High removal rate: The sewage treatment equipment of food processing plants makes full use of the strong hydrolysis ability of anaerobic microorganisms and strong oxidation ability of attached growth aerobic microorganisms, and realizes the organic coupling of the main functions of the two microorganisms and the integration of technology, which is more than conventional The treatment process has higher organic removal efficiency and can treat organic wastewater with high suspended solids content.
2. Energy saving: Food processing sewage treatment equipment has simple process structure, low capital investment cost, strong flexibility, and can operate under high organic load rate conditions. Since the anaerobic hydrolysis acidification reactor and the trickling filter bed reactor hardly need oxygen supply, energy consumption and operating costs are greatly saved.
3. Stable operation: Due to the strong adaptability of anaerobic hydrolysis bacteria, the operation stability of sewage treatment equipment in food plants is better than that of conventional treatment processes, and it is easy to recover from shock loads, easy to operate and manage, and has a wide range of applications.
