Tunnel construction wastewater cyclic utilization device

Abstract

The invention discloses a tunnel construction wastewater cyclic utilization device. The tunnel construction wastewater cyclic utilization device structurally comprises an equipment main body, a waterinlet, a water outlet, an inspection opening, a draught fan, an adjusting tank, a grid, a submersible sewage pump, a detection mechanism, an oxygen-lack tank, a composite contact oxidization tank, a biological film, a sludge treatment tank, a blow-off pipe and a clean water tank, wherein the equipment main body is of a box shape; the water inlet is formed in the middle part of the right surface ofthe equipment main body; the water inlet is connected with the equipment main body through electric welding; the water outlet is formed in the middle part of the left-side surface of the equipment main body; the water outlet is connected with the equipment main body through electric welding; the inspection opening is formed in the left side of the upper surface of the equipment main body; the inspection opening is connected with the equipment main body through electric welding. The tunnel construction wastewater cyclic utilization device disclosed by the invention has the beneficial effects that the detection mechanism is arranged and the automation degree of utilizing the submersible sewage pump is improved; a condition that the device does idle work under a water-free condition so thatgreat-extent loss of the submersible sewage pump is caused is avoided, the practicability of equipment is effectively improved and the cost of the equipment is saved.

Description

technical field [0001] The invention relates to a tunnel construction wastewater recycling device, which belongs to the field of wastewater recycling devices. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that is difficult to purify after primary pollution and cannot meet a certain standard. [0003] However, in the prior art, no matter how high the water level is inside the equipment, the submersible sewage pump is still working, which will easily cause the submersible sewage pump to be worn and replaced frequently. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a ...
