A water-saving device for reuse of small-scale manual car washing water

Abstract

The invention discloses a water-saving device for reuse of small-scale manual car washing water, which comprises a sewage water inlet pipe, an upward flow sedimentation filter, a backwashing device and a water tank. One end of the water inlet pipe is connected with the upward flow sedimentation filter. The above-mentioned upward flow sedimentation filter includes a sedimentation area and a filter area, and a backwashing device is arranged between the upward flow sedimentation filter and the water tank, and the backwashing device is composed of a spray head, a lift pump, a control valve and an air hole , the air hole and the spray head are set on the top of the upward flow sedimentation filter, the commission pump is set in the water tank, the lift pump and the spray head are connected by a backwash water pipe, and the backwash water pipe is A control valve is provided. The device of the invention is simple, can effectively remove car washing waste cement, sand and suspended particles, can meet the requirements of car washing and recycling, saves water resources, and avoids the complicated and complicated process of treating surfactants and organic matter in the past, and is more efficient. Cost-effective 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 ...
