Problems solved by technology

[0003] At present, the treatment process used for kitchen wastewater is usually simple civil construction or stainless steel grease trap. The grease trap can partially separate the oil and water in the kitchen wastewater, but the separated sewage still has a high COD (ChemicalOxygen Demand, chemical oxygen demand), BOD (Biochemical Oxygen Demand, biological oxygen demand) high-concentration organic wastewater, directly discharged into the sewage pipe network will increase the sewage load of the pipe network, so a more effective method is sought It is of great significance to discharge kitchen waste water to meet the standards

Embodiment 1

[0028] see figure 1 , the invention discloses a waste water purification device for kitchen waste treatment, comprising a primary settling tank, a collection bucket, a three-stage oil-water separation tank, a regulating tank, an anaerobic tank, an aerobic tank, a secondary settling tank and a sterilization and disinfection unit ,in,

[0029] The primary settling tank is connected with the collection barrel and the third-stage oil-water separation tank respectively, and the primary settling tank outputs floating oil to the collection barrel, and oil-water output to the third-stage oil-water separation tank; the third-stage oil-water separation tank outputs separated oil to the collection barrel. oil, and output the separated sewage to the adjustment tank; the adjustment tank, anaerobic tank, aerobic tank, secondary settling tank and sterilization and disinfection department are connected in sequence to degrade the sewage, remove organic matter and sterilize and disinfect, and t...

Embodiment 2

[0032] It also includes a composter, which is respectively connected with the primary settling tank, the tertiary oil-water separation tank and the secondary settling tank. And a screw extruder is set between the primary settling tank and the compost machine to separate, squeeze and stir the coarse slag output from the primary settling tank; or a plate and frame filter press is set between the primary settling tank and the compost machine to The coarse slag output from the tank is separated, squeezed and stirred. The settled sediment and sludge are collected and utilized as resources for aerobic composting and converted into organic fertilizer raw materials

Embodiment 3

[0034] In the three-stage oil-water separation tank, the oil and water are further separated from oil and water to realize the comprehensive separation of oil, water and slag. The floating oil part can be equipped with an automatic oil skimming device, and the skimmed oil is automatically collected. A water pump is set between the regulating tank and the anaerobic tank to regulate the water volume.

[0035] The dissolved oxygen in the anaerobic pool is less than 0.2mg / L; the dissolved oxygen in the aerobic pool is greater than or equal to 2mg / L. The anaerobic pool is conducive to the reproduction of the anaerobic microbial community, and the effective degradation of COD and ammonia nitrogen in the wastewater. The degraded The range of COD and ammonia nitrogen needs to be determined according to the quality of the influent water. The degradation rate of COD and ammonia nitrogen can reach 90%. After the anaerobic tank, the sewage reaches the aerobic tank. Under aerobic conditions...

Abstract

The invention discloses a waste water purification device for kitchen waste treatment and a method thereof. The device comprises a primary sedimentation tank, a collecting barrel, a three-stage oil-water separation tank, an adjusting tank, an anaerobic tank, an aerobic tank, a secondary sedimentation tank and a sterilization and disinfection part, wherein the primary sedimentation tank is connected with the collecting barrel and the three-stage oil-water separation tank, and the primary sedimentation tank outputs floating oil to the collecting barrel; oil and water are output to the third-stage oil-water separation tank; the third-stage oil-water separation tank outputs separated oil to the collecting barrel and outputs separated sewage to the regulating tank; wherein the regulating tank,the anaerobic tank, the aerobic tank, the secondary sedimentation tank and the sterilization and disinfection part are connected in sequence to degrade, remove organic matters and sterilize and disinfect sewage. According to the method, the complete life cycle of oil, water and slag is comprehensively considered, each part is subjected to harmless and resource utilization, secondary pollution is avoided, and environmental protection benefits are achieved.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a waste water purification device and method for treating kitchen garbage. Background technique [0002] With the continuous development of social economy and culture, people's living standards are increasing day by day, people's demand for food is increasing day by day, and the number of restaurants, hotels, and canteens is increasing, resulting in a large amount of kitchen waste. In the on-site reduction process of food waste, if the oily sewage generated by material crushing, extrusion and dehydration is directly discharged to the urban sewer pipes, it will generate a large oil pollution load on the urban sewer pipe network. It is easy to be blocked after entering the pipe network for a long time. Therefore, collecting and effectively separating kitchen waste water from oil and water is an effective measure to avoid blockage and failure of urban pipe networks, and...
