Small water saving apparatus for reusing manual car wash water

Abstract

The invention discloses a small water saving apparatus for reusing manual car wash water. The apparatus comprises a sewage inlet tube, an upward flow deposition filter tank, a backwashing device and awater tank, one end of the water inlet tube is connected with the upward flow deposition filter tank, the upward flow deposition filter tank comprises a deposition area and a filtering area, the backwashing device is arranged between the upward flow deposition filter tank and the water tank, the backwashing device is formed by a water spraying head, an elevator pump, a control valve and an air vent, the air vent and the water spraying head are arranged at the top of the upward flow deposition filter tank, the elevator pump is arranged in the water tank, the elevator pump is connected with thewater spraying head through a backwashing water tube, and the backwashing water tube is provided with the control valve. The apparatus is simple, can effective remove silts and suspended particles inthe car wash wastewater to meet the requirements of car wash flushing reuse, avoids previous treatment of surfactants and organic matters and other tedious and complicated processes, and is economical, efficient and practical.

Description

technical field [0001] The invention belongs to the technical field of water treatment and reuse, in particular to a water-saving device for recycling water from a small manual car wash. Background technique [0002] At this stage, car wash water is mostly used for one-time use, and then discharged into sewage pipes, resulting in a great waste of water resources. Although various types of car wash wastewater recycling equipment emerge in endlessly on the market, they can be roughly divided into two categories: one is equipment for advanced treatment of wastewater. Although it can achieve better effluent quality, it has many treatment processes and is difficult to operate and maintain. The investment cost is as high as that of a small sewage treatment plant, and it is difficult to be widely used. For example, the existing technology is divided into pretreatment unit, fine treatment unit and advanced treatment unit, which involves devices such as sand filter tank, regulating ...

Problems solved by technology

[0003] Purpose of the invention: In order to overcome many shortcomings such as high cost, complex equipment, and unstable treatment effect of the existing car wash wastewater treatment and circulation device, the present invention provides a simple treatment of car wash wastewater according to the characteristics of car wash wastewater rich in particles and foam, It can only remove the suspended particles and foam in the car wash wastewater, and it can be used as the head flush of the car wash without adding chemicals. It has a reasonable structure, simplifies the complicated sewage treatment procedures, and achieves the purpose of water saving and cost reduction. water saving device
