Problems solved by technology

The gravity transportation method has many disadvantages such as leakage, leakage pollution, discharge pollution, blockage and overflow, and high maintenance cost. It requires the construction of gravity lifting pump stations, large excavation works, and laying of large-scale pipeline networks. The construction cost is high and the construction period is long. question

Abstract

A vacuum drainage system includes a vacuum pump group, a vacuum can, a vacuum trunk conduit, vacuum branch conduits, a biological filter, a dredge pump group, a plurality of collecting devices, a plurality of vacuum demarcation valves, and a control device. The biological filter, the vacuum pump group, the dredge pump group and the vacuum can constitute a vacuum power station, the intake port of the vacuum pump group is connected with the vacuum can through conduits as well as a stop valve; the aspirating pipe of the dredge pump group is connected with the vacuum can through conduits, and the discharging tube is connected with the water quality treatment plant or higher level pipe network; the vacuum trunk conduit is connected with the vacuum can and extends to the user site collecting device from the place, the plurality of collecting devices are distributed at each user site, which are connected to the vacuum trunk conduit through the vacuum branch conduits; the vacuum demarcation valves are mounted on the vacuum branch conduits; the control device is connected with liquid level detectors in the vacuum pump group, the dredge pump group as well as the collecting devices; pressure testing sensors in the vacuum demarcation valve and the vacuum can; and the like.

Description

technical field [0001] The present invention relates to a fluid collection and conveying technology and system, in particular to a vacuum drainage and sewage discharge system for vacuum energy storage drainage and sewage discharge technology and system. The system is used to store sewage from vacuum sewage pipes and then transport the sewage to sewage treatment plants or similar. Background technique [0002] At present, there are three ways of collecting and transporting rainwater, waste water and sewage in developed countries in the world, gravity, vacuum and pressure. China currently collects and transports rainwater, waste water, and sewage only by traditional gravity. The gravity transportation method has many disadvantages such as leakage, leakage pollution, discharge pollution, blockage and overflow, and high maintenance cost. It requires the construction of gravity lifting pump stations, large excavation works, and laying of large-scale pipeline networks. The constr...
