The treatment of restaurant sewage is an important step to ensure hygiene and safety. The correct treatment method can effectively avoid blocking or dirt retention, and at the same time avoid the generation of odor and pests. The following are some common treatment methods for restaurant sewers.

1. sedimentation tank method: before the catering water flows into the sewer, the wastewater is preliminarily treated by setting a sedimentation tank. Sedimentation tank can filter out most solid wastes and impurities, make wastewater cleaner and reduce the burden of subsequent treatment.

2. biochemical pool method: this method is to add some biochemical enzyme preparations to waste water to decompose organic substances into harmless substances, thus achieving the purification effect. The sludge layer of biochemical pool can play a role in weakening odor.

3. Cyanobacteria method: Cyanobacteria can adsorb ammonia and reduce the generation of odor. Putting some cyanobacteria into the sewer can effectively reduce the odor.

4. network cleaning method: oil stains and residues used in restaurant kitchens should be cleaned regularly. At the same time, it is necessary to clean up the sewers and drains to prevent large particles of garbage from entering the sewers.

5. pH adjustment method: In the process of sewage treatment, attention should be paid to maintaining a certain pH balance to avoid over-acidity or over-alkalinity.

6. Regular cleaning method: clean the pipeline regularly every quarter or half a year to thoroughly remove residue, dirt and odor.

The above are some methods for treating restaurant sewage. Each method has its advantages and disadvantages, and cannot be used alone. The catering industry should choose suitable methods for treatment according to the actual situation to ensure the purification effect of wastewater.
