Application of screw sludge dehydrator in kitchen waste water treatment

 

Features of kitchen waste water:

During the stacking and processing of kitchen waste, a high concentration of organic or inorganic sewage is produced due to biochemical degradation such as compaction and fermentation. The composition of sewage is complex, the concentration of pollutants is high, it emits an extremely unpleasant odor, and the quality of sewage is extremely unstable. Compared with the quality of sewage in the urban pipe network, its main pollutant indicators exceed a lot. It will cause shock load to the sewage treatment plant and affect the stable operation of the sewage treatment plant.

Kitchen waste water production:

Kitchen waste sewage is the sewage generated by the catering industry. The development of the catering industry has brought a large amount of kitchen waste sewage. For food safety, kitchen waste cannot be directly used as feed. Therefore, it must be treated harmlessly to avoid polluting the environment and affecting human beings. healthy. The treatment of kitchen waste water should take into account the treatment effect, economy and ease of operation.

In which stage is screw sludge dehydrator used in kitchen waste water?

Kitchen waste sewage contains a large amount of residues and leftovers. The common treatment method is to first use a pulverizer to pulverize the large particles inside, and then enter the adjustment tank, and then enter the air flotation machine after adjustment. In the oxygen and aerobic links, through anaerobic and aerobic treatment, the organic matter in the sewage is decomposed, the sewage enters the sedimentation tank, and then the solid-liquid separation of the sludge is realized by the screw sludge dehydrator, and the sludge in the sewage is squeezed out.

Screw sludge dehydrator is very important as a part of sludge treatment in kitchen waste sewage treatment. After treatment, the sewage is basically clear, and the sludge is squeezed into a mud cake. Finished work for kitchen waste water treatment.

Advantages of screw sludge dehydrator:

1. The product specifications are diverse and the series are complete. According to different processing scales, suitable models can be selected to avoid overkill.

2. The design of the body is compact, and the concentration and dehydration are integrated. It has auxiliary devices such as electric control cabinet and sludge flocculation mixing tank. It has strong compatibility with supporting equipment and is easy to design.

3. The small design is convenient for adjusting measures to local conditions, which can reduce the footprint and construction cost of the dehydrator itself.

4. It has the function of sludge concentration, so it does not need a concentration and storage unit, which reduces the overall footprint and construction cost of the sewage treatment facility.

5. The main body has a self-cleaning function, so it is not necessary to wash with a lot of water to prevent sludge clogging.

6. Using low-speed screw extrusion technology, low power consumption.

7. The electric control cabinet is equipped with an automatic control device, which realizes 24-hour automatic and continuous unmanned operation from conveying sludge, injecting liquid medicine, concentrating and dehydrating, and discharging mud cake, reducing labor costs.
