Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an assembled temperature-increasing and heat-insulating sewage treatment pool. Background Art

[0002] The treatment effect and speed of domestic sewage are closely related to the current temperature of the sewage treatment pool. When the current temperature of the sewage treatment pool is high, the activity of enzymes and microorganisms is high, the sewage treatment effect is good, and the sewage treatment speed is fast; when the current temperature of the sewage treatment pool is low, the activity of enzymes and microorganisms is low, the sewage treatment effect is relatively poor, and the sewage treatment speed is relatively slow.

[0003] The weather in some parts of the north is cold in winter, and low temperature has become the main constraint on the effect and speed of domestic sewage treatment. In addition, the existing sewage treatment tanks are often integrated steel-concrete structures with relatively complex internal structures. For sewage with different treatment requirements and different treatment scales, each tank unit of the sewage treatment tank needs to be customized in design and production. The integrated steel-concrete structure has poor flexibility and a long construction period. In some cold areas in the north, sewage treatment equipment is often installed below the permafrost layer. The construction, maintenance and repair of sewage treatment equipment are difficult, and the operation and management are difficult, which is not conducive to the continuous and normal operation of sewage treatment equipment. There is no sewage treatment tank on the market that can flexibly assemble each tank unit, heat and insulate each tank unit, and can continue to operate normally. Therefore, there is an urgent need for an assembled heating and insulation sewage treatment tank with flexible assembly, good heating and insulation effects, and normal operation throughout the entire period, which is a technical problem that technicians in this field urgently need to solve.
