Device for treating polyester beverage bottle recycling sewage

Abstract

The invention relates to a sewage treatment device for reusing polyester beverage bottles, which comprises a frame and a working platform arranged on the frame. Guardrails are arranged on both sides of the working platform, and the working platform is connected with stairs. There is a filter device on the frame, a sedimentation device is installed under one end of the filter device, and the other end of the filter device is connected to the sludge collection tank. The collection tanks are all connected with the sludge press. The invention carries out flocculation, sedimentation, filtration and pressing on the sewage from the cleaning process, so that the mud becomes mud, and the pressed water is sent to the filter screen for circulation through the sewage pump, so as to realize reuse. It fundamentally solves many problems in the process of recycling beverage bottles, reduces labor intensity, improves work efficiency, reduces operation risks, saves water, and at the same time completely solves the secondary pollution of waste water and waste residues to meet the development requirements of circular economy.

Description

technical field [0001] The invention relates to a polyester beverage bottle recycling equipment, in particular to a polyester beverage bottle recycling sewage treatment device. Background technique [0002] The "white" environmental pollution caused by waste plastics has become a worldwide problem, and the raw materials of plastics mainly come from non-renewable fossil fuels such as coal, oil, and natural gas. With the increasingly tense global energy supply and rising oil prices, the The recycling of waste plastics can not only solve the "white" environmental pollution, but also save resources and alleviate the energy crisis brought about by social development, so it has attracted more and more attention from all over the world. [0003] Polyethylene terephthalate is a thermoplastic polyester that is widely used. The waste plastics that can be recycled and reused are polyester bottles (including beverage bottles, mineral water bottles, oil bottles, and barrels). The recycl...

AI Technical Summary

Problems solved by technology

The characteristics are that the production process is simple, the investment in production equipment is small, and the flexibility is relatively large. However, the quality of the recycled polyester material is relatively poor, and it is difficult to meet the high-standard requirements of downstream manufacturers. The number of workers is large, energy consumption is high, and water volume is large. , especially without sewage treatment facilities, it is easy to cause secondary pollution to the environment in the process of recycling polyester beverage bottles
