Environment-friendly system for comprehensively treating sewage and wastewater

Abstract

The invention discloses an environment-friendly system for comprehensively treating sewage and wastewater. The system comprises a water collection device, a first storage device, a purification device, a second storage device, a detection device and a third storage device, wherein the water collection device, the first storage device, the purification device and the second storage device are connected by pipelines in sequence; the second storage device is connected with the third storage device and the purification device respectively via three-way valves; the detection device is installed at the front end of one three-way valve; the water collection device comprises a filter screen, a water diversion pipeline and a water flow control valve; the first storage device comprises a plurality of water storage tanks, an overflow opening, a drain valve and a blow-down valve; and the purification device comprises a filter tank, a flocculating settling tank, an activated carbon treatment tank and a sterilization tank. The sewage and wastewater treatment system provided by the invention occupies small space, is convenient and fast in the treatment process, has good treatment effects, high efficiency and high resource utilization rate, is low in cost, ensures high water quality after treatment, is economical and environmentally friendly and has a wide range of application.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an environmental protection system for comprehensive treatment of sewage and wastewater. Background technique [0002] Water is the most basic condition for people to survive and develop. People use water every day and produce sewage at the same time. Especially in today's society with the rapid development of industry and agriculture, the output of sewage and waste water is increasing day by day. If it is not properly treated, it will not only pollute the environment, but also waste water resources. Although natural water resources are abundant, the amount of water that can be used by people is limited, and due to increasingly serious environmental pollution problems, water resources are scarce in some areas, so rational use of sewage and waste water can not only solve the problem of water shortage , can also reduce the waste of resources. Therefore, in recent years, s...

AI Technical Summary

Problems solved by technology

There are many sewage or industrial wastewater treatment systems, but most of the treatment systems are highly specialized, and the efficiency of sewage and wastewater treatment is not high, and some treatment processes will cause secondary pollution to the environment. The water quality is not guaranteed, and sometimes the impurities in the sewage and wastewater will block the pipelines in the treatment system, affect the treatment effect, reduce the treatment efficiency, shorten the service life of the equipment, and bring more expensive inspection and maintenance costs
