Dishwashing sewage treatment equipment The process flow of dishwashing sewage treatment equipment mainly includes the following steps:
Sewage collection: The sewage generated during the dishwashing process is collected into the sewage tank.
Pretreatment: Remove large particles of impurities and solid debris in the sewage, such as vegetable residue, bones, meat residue, etc., through grids, screens and other equipment. At the same time, grease is removed from the sewage through equipment such as grease traps.
Regulating tank: Since the quantity and quality of dishwashing sewage will fluctuate with time and the business situation of the catering industry, it is necessary to balance the flow and concentration of sewage through the regulating tank to ensure the stable operation of the follow-up treatment equipment.
Biochemical treatment: The sewage in the regulating tank is passed through biological treatment equipment, such as AO biochemical tank, etc., and the organic matter in the sewage is decomposed into harmless substances by the action of microorganisms.
Filtration and disinfection: Filters and disinfection equipment are used to remove microorganisms such as suspended solids and bacteria in the sewage, so that the water quality is further improved.
Discharge: The sewage after the above treatment can meet the environmental protection requirements and can be discharged.
It should be noted that the process flow of different tableware cleaning sewage treatment equipment may be slightly different, and the specific process needs to be designed and selected according to the actual situation. At the same time, the operation and maintenance of the equipment also need professional technicians to manage and operate to ensure the normal operation and processing effect of the equipment.
