Bread is the staff of life. All aspects of the food industry are social hot spots and focus issues. The food industry has a wide range of raw materials and various products, and the quantity and quality of discharged wastewater are much different from that of ordinary domestic sewage. The main pollutants in wastewater are solid substances floating in wastewater, such as vegetable leaves, peels, ground meat, poultry feathers, etc. The substances suspended in wastewater include grease, protein, starch, colloid, etc. Acid, alkali, salt, etc. dissolved in wastewater; Sediment and other organic matters entrained in raw materials; Pathogenic bacteria, etc.

 

  The general characteristics of food industrial wastewater are high content of organic substances and suspended solids, easy to rot, and generally non-toxic. Its harm is mainly to make the water eutrophication, resulting in the death of aquatic animals and fish, prompting the odor of organic matter deposited on the bottom of the water, worsening the water quality and polluting the environment. In addition to proper treatment according to water quality characteristics, biological treatment is generally appropriate for food industrial wastewater treatment. If the effluent quality is very high or the content of organic matter in wastewater is high, two-stage aeration tank or two-stage biofilter, or multi-stage biological rotary table, or a combination of two biological treatment devices, or an anaerobic-aerobic series biological treatment system can be adopted.

 

  According to the characteristics of sewage from foreign trade food companies, the AO+MBR process is adopted by Zhongqiao Qidi foreign trade integrated sewage treatment equipment. Here, Xiaobian introduces the advantages of Zhongqiao Qidi foreign trade food integrated sewage treatment equipment:

1, the process is simple, the occupied area is small, and the effluent quality is good.

2. It can keep the high concentration of microorganisms in the biological treatment unit and greatly increase the volume load. At the same time, efficient membrane separation greatly shortens the hydraulic retention time of the treatment unit and reduces the occupied area of the bioreactor.

3. The loss of microbial flora is small, which is conducive to the growth of slow-growing nitrifying bacteria, so that various metabolic processes in the system can proceed smoothly.

4. Some polymer refractory organics have a long residence time, which is conducive to their decomposition.

5. MBR integrated urban sewage treatment equipment is the same as other filtration and separation technologies. In the long-term running process, the membrane as the filter medium is blocked, and the running time of the membrane in water is gradually shortened. Effective backwashing and chemical cleaning can restore membrane flux and maintain the effective service life of MBR system.

6. MBR technology is applied to urban sewage treatment, with simple process and convenient operation, which can realize automatic operation and management.

7. To facilitate the overall planning and layout of users, and change the previous cognition of sewage treatment equipment, paint is sprayed to the outside.

8. Flat MBR membrane is adopted, which has no broken line and good mechanical strength. Non-woven fabric is used as supporting layer in the film, which has strong wear resistance. The flat plate is easy to replace, and the damaged film can be replaced by itself.
