Abstract

The invention belongs to the technical field of wastewater treatment and particularly relates to a positive pressure wastewater-lifting mechanism for basements, comprising a compressor and a pressureexchange device. A wastewater collector is fitly arranged below the pressure exchange device; a wastewater collection tank is arranged below the wastewater collector and is connected with an externalwastewater collection pipe via a wastewater collection connector; a floater is fitly arranged on the wastewater collection tank and is provided with an ejector rod; a blow-down connector is fitted below the wastewater collection tank and is fitly connected with a discharge pipe; the other end of the discharge pipe is connected with a gravity pipe of a drainage system. The positive pressure wastewater-lifting mechanism for basements is driven by negative pressure, has delayed turn-on and turn-off, and has controllable time, high response speed, thorough wastewater discharge and zero odor; the positive pressure wastewater-lifting mechanism for basements is rarely damaged in moist environments and therefore, has long service life.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a basement positive pressure sewage lifting mechanism. Background technique

[0002] The basement refers to the height of the room floor below the outdoor ground level exceeding half of the clear height of the room. Multi-storey and high-rise buildings need a deep foundation. In order to utilize this height, a basement is built under the bottom of the building, which can increase the usable area and save the backfilling of the house core, which is relatively economical. Building a basement below the ground floor of a house can improve the efficiency of building land use. Some high-rise building bases are deeply buried, and making full use of this depth to build basements has good economic and use effects. The outer wall and floor of the basement are deeply buried in the ground and are infiltrated by water in the soil and groundwater. Therefore, the problem of moisture-...
