A device for treating and recovering waste water from washing kitchen waste collection vehicles

Abstract

The invention discloses a washing waste water treatment and recovery device for kitchen waste collection vehicles, and relates to the technical field of waste water treatment. Oxygen tank, MBR membrane tank, grille, sludge tank, screw dewatering machine, clear water tank and supporting dosing system are integrated into the same device, which has a compact structure, small footprint and low cost, which is cheaper than traditional water treatment facilities. Significantly lower, the cost of traditional facilities is high, the land occupation is large, the temporary construction takes a long time, and it is not convenient enough. It is not suitable for the treatment of flushing wastewater from kitchen waste collection vehicles with small water volume. However, the device can be consigned to the place of use immediately after production Installation does not require temporary construction and saves time. Therefore, the device has the advantages of compact layout, low investment cost, low operating cost, very convenient operation and maintenance, high washing wastewater treatment efficiency and good treatment effect, and realizes sludge reduction. , The advantages of sewage reuse.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a device for treating and recovering waste water from washing kitchen waste collection vehicles. Background technique [0002] Since the implementation of waste classification collection and treatment, the kitchen waste collection vehicle needs to wash the vehicle after unloading the waste and before returning to the parking center, resulting in flushing wastewater. The concentration of the flushing wastewater is not as high as that of the kitchen waste extrusion wastewater, but it is much higher than the domestic sewage water quality, which cannot be directly piped for treatment, and the treatment is difficult. [0003] In addition, there are generally about 20-30 food waste collection vehicles parked in a parking area, and the daily waste water volume is about 5-10m 3 , the amount of water is small, and it is very uneconomical to build traditional treatment facilities for ...

AI Technical Summary

Problems solved by technology

The concentration of the flushing wastewater is not as high as that of the waste water squeezed from food waste, but it is much higher than the quality of domestic sewage, so it cannot be directly piped for treatment, and the treatment is difficult

[0003] In addition, there are generally about 20-30 food waste collection vehicles parked in a parking area, and the daily waste water volume is about 5-10m 3 , the amount of water is small, and it is very uneconomical to build traditional treatment facilities for treatment. For this type of wastewater, there is still a lack of corresponding treatment methods and devices. As a result, washing wastewater from kitchen waste collection vehicles is a difficult problem in sewage treatment technology.
