Abstract

The invention relates to the technical field of wastewater environment-friendly structures, and discloses a dual anti-seepage and anti-corrosion structure of a wastewater lifting device in order to solve the problem that in the prior art, a wastewater lifting device is poor in anti-seepage and anti-corrosion durability. The structure comprises an inner high-strength glass fiber layer (1), a firstmiddle layer (2), an inner structural layer (3), a second middle layer (4) and an outer high-strength glass fiber layer (5) which are arranged in sequence. On the basis of an existing double-layer storage tank, the high-strength glass fiber layer anti-corrosion and anti-seepage structures are additionally arranged on the inner wall and the outer wall of the storage tank at the same time, and the dual structure comprises the modified polytetrafluoroethylene resin coating and the high-strength glass fibers which are tightly combined; apart from strong bearing ability, the structure has high corrosion resistance, permeation resistance and durability to wastewater, so that the problems of poor anti-seepage effect and over-high manufacturing cost of an existing water pool and an upgraded form thereof are solved, and the structure with good anti-seepage and anti-corrosion effects is obtained.

Description

technical field [0001] The invention relates to the technical field of waste water environmental protection structures, in particular to a double anti-seepage and anti-corrosion structure of a waste water lifting device. Background technique [0002] With my country's economic development and industrial upgrading, the awareness of ecological environment protection and safety has become more and more popular, and at the same time, higher requirements have been put forward for the prevention and control of environmental pollution of chemical enterprises. The traditional buried pipe drainage method is subject to many restrictions. Many chemical industry parks clearly require that the wastewater of chemical enterprises must be equipped with wastewater collection tanks and then pumped to sewage treatment stations. "Upgraded version to achieve the purpose of easy observation after leakage. The drainage of the traditional sump needs to dig and build a cast-in-place reinforced conc...
