Wastewater and rainwater cyclic utilization device in house building construction site

Abstract

The invention relates to a wastewater and rainwater cyclic utilization device in a house building construction site. The device comprises a slab, a first filter cabin and a second filter cabin; the device is characterized in that the slab is a rectangular trolley bottom plate (1); the first filter cabin (3) and the second filter cabin (15) are arranged on the bottom plate at an interval; a cavityof the first filter cabin is divided into three layers of space by flow guide blocks and a first filter plate; a second filter plate (22) is horizontally arranged at the middle part of a cavity of thesecond filter cabin (15); three groups of filter liners (23) are arranged in the cavity of the second filter plate at intervals side by side; and a liquid discharging port is arranged at the lower end of the side wall of the bottom of the second filter cabin. The wastewater and rainwater cyclic utilization device in the house building construction site according to the invention has the advantages that a purification device is elaborate in design, simple in structure and convenient to manufacture, and can perform cleaning and operation automatically; the purification property is excellent; and the cost of wastewater and rainwater purification engineering is reduced.

Description

technical field [0001] The invention relates to a water recycling device, in particular to a device for recycling waste water and rainwater at a building construction site. Background technique [0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. [0003] In recent years, my country's economy has developed rapidly, and the construction industry plays an important role in the process of this rapid economic development. At the same time, behind this rapid economic development, various resources consumed in the engineering field It is astonishing, especially the phenomenon of waste of water resources is becoming more and more serious. Combined with my country's national conditions, combined with the country's proposal to create a resource-saving society, combined with the scientific development concept and susta...

AI Technical Summary

Problems solved by technology

[0004] In the process of using and treating existing rainwater and wastewater recycling equipment, most of the large particles in the wastewater are simply treated to remove impurities. The treated wastewater is still very turbid and can be used in limited places, and equipment treatment After the wastewater is discharged, a large amount of filtered waste will be stored in the inner cavity of the equipment. A large amount of waste can easily cause blockage of the treatment equipment and require continuous cleaning. Frequent cleaning makes the workload of the operator very heavy, and the equipment is not easy to clean Disassembly, frequent disassembly is likely to cause some failures of the equipment and reduce the service life of the equipment

[0005] Therefore there are above-mentioned inconveniences and problems in known rainwater and waste water recycling equipment
