Embodiment Construction

[0018] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions.

[0019] Such as figure 1 , 2 , 3, the sewage in the urban sewage pipe network 1 flows into the automatic decontamination device 3 along the sewage inlet pipeline 2 by virtue of the water level difference. The motor 9 and the reducer 10 drive the filter cartridge holder 15 through the rotating rod 12 and then drive the orifice plate filter cartridge 16 to rotate. Urban sewage flows into the device along the sewage inlet pipeline 2, and enters the rotating orifice plate filter cartridge 16. The treated sewage is pumped by the circulating pump 4 and enters the heat exchanger 7 through the water outlet pipeline 5. After heat exchange, The sewage is returned to the urban sewage pipe network 1 by the drainage pipeline 6 . In the sewage treatment process, the dirt and sundries attached to the outer wall of the ...

Abstract

A method for taking water from the sewage pipe in urbane area by use of the potential difference between said sewage pipe and automatic sewage treating apparatus features that said sewage automatically flows into the automatic sewage treating apparatus to obtain clean water. Said automatic sewage treating apparatus is composed of orifice-plate filter cylinder, motor, speed reducer, overflow port, blowoff pipe, water spraying pipe, submersible pump, circulating pump, blowoff pump, etc.

Description

technical field [0001] The invention belongs to the technical field of natural energy utilization, and relates to a sewage water intake method and an automatic decontamination device, in particular to a water intake method and an automatic decontamination device for utilizing low-level heat energy of sewage in urban sewage pipe networks. Background technique [0002] Urban sewage is an available low-temperature energy source, especially untreated urban sewage has not yet been developed and utilized on a large scale. In recent years, although my country's water source heat pump technology has developed rapidly, it is limited by the shortage of water resources. Therefore, the development and utilization of urban sewage, a low-temperature energy source, has increasingly attracted people's attention. Compared with groundwater water source heat pumps, sewage water source heat pumps do not need to pump groundwater from the ground, nor do they need to refill the ground with circula...
