Sewage purification and recycling integrated device of multifunctional cleaning and sweeping vehicle

Abstract

The invention belongs to the technical field of water treatment equipment, and relates to a sewage purification and recycling integrated device of a multifunctional cleaning and sweeping vehicle. The sewage purification and recycling integrated device comprises a grid grit tank system, a preliminary sedimentation tank system, a clean water tank system and a coagulative precipitation tank system, wherein the grid grit tank system is connected with the preliminary sedimentation tank system by a preliminary sedimentation tank overflow water inlet; the preliminary sedimentation tank system is connected with the coagulative precipitation tank system by a preliminary sedimentation tank water outlet pipe and a coagulative precipitation tank water inlet pipe; the coagulative precipitation tank system is connected with the clean water tank system by a coagulative precipitation tank water outlet pipe and a disinfection mixing tank water inlet pipe; and outlet water of the clean water tank system is supplied by a clean water tank water outlet pipe for recycling. The device is used for sewage treatment of the cleaning and sweeping vehicle; outlet water of the device can be directly recycled for cleaning and sweeping a pavement and flushing bottom mud of the multifunctional cleaning and sweeping vehicle; the recycling efficiency of sewage is improved; 50% of fresh water can be saved; emission of the sewage and sundries to a municipal pipe network is reduced; and the social, environmental and economic benefits are significant.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and relates to an integrated device for purifying and recycling sewage of a multi-functional washing and sweeping vehicle. Background technique [0002] Due to the dry climate and more dusty weather in the north, with the improvement of urban environmental requirements, major cities in the north have gradually introduced multi-functional cleaning vehicles. The application of multi-functional cleaning and sweeping vehicles can achieve the dual functions of road cleaning and watering, and can also reduce the generation of dust in the process of urban cleaning. The multi-functional washing and sweeping vehicle sprinkles 9 tons of water at a time during the operation, and the recycled water is about 5 tons. The recycled water contains a large amount of garbage, sludge and organic matter. At present, most of the recovered water is directly discharged into urban sewage pipes without ...

AI Technical Summary

Problems solved by technology

At present, most of the recovered water is directly discharged into urban sewage pipes without treatment, which not only causes a lot of waste of water, but also increases the load of urban sewage treatment

At the same time, the bottom mud washing system carried by the multi-functional cleaning and sweeping vehicle itself is driven by the engine of the multi-functional cleaning and sweeping vehicle itself and the bottom mud is washed by spraying water mist, resulting in insufficient bottom mud washing of the multi-functional cleaning and sweeping vehicle.
