Integrated sewage treatment and reuse device

Abstract

The invention provides an integrated sewage treatment and reuse device. The integrated sewage treatment and reuse device comprises a water collecting tank, a biological reaction tank, a sedimentation tank, a biological aerated filter and a water storage tank which are sequentially arranged and closely connected, a water inlet pipe is connected to the water collecting tank, and a water supply pipe is connected to the water storage tank; sewage automatically flows into the water collecting tank from the water inlet pipe, a lift pump is arranged at the bottom of the water collecting tank, automatic flowing of the sewage is achieved after the sewage is lifted by the lift pump, the sewage enters the biological reaction tank, the sedimentation tank and the biological aerated filter to be treated, the sewage meets the reuse water standard after being treated, the treated sewage is collected into the water storage tank, and the sewage is lifted by a water supply pump in the water storage tank and supplied to a user to be directly used through the water supply pipe. According to the integrated sewage treatment and reuse device, the design of integrated gapless combination of the five units is achieved, a three-grade sewage treatment technology is adopted, the effluent quality is stable, the water quality standard is higher, and the requirements of the water quality of the sewage which is treated to be serve as non-drinking water are completely met.

Description

technical field [0001] The invention relates to an integrated sewage treatment and reuse device, which belongs to the technical field of machinery. Background technique [0002] With the accelerated development of our country's social economy, the recycling and utilization of sewage has become the main technical direction of the development of sewage treatment in our country at this stage. The current large-scale sewage treatment and recycling treatment plants have relatively complicated treatment processes, and there are many monomers in each section of the plant. However, this kind of process and technical route is not suitable for relatively small decentralized sewage treatment projects due to too many monomers and high management requirements. [0003] Most of the current domestic integrated sewage treatment devices focus on sewage treatment to discharge standards, and there are few integrated sewage treatment and reuse devices. The process from sewage treatment to dis...

AI Technical Summary

Problems solved by technology

The process from sewage treatment to discharge standard equipment is relatively simple, while sewage treatment and reuse equipment has high requirements on water quality, and at the same time needs to set up reuse water pools and water reuse equipment, resulting in low integration, large footprint, scattered monomers, and difficult management Disadvantages such as complexity

Ultimately, the promotion and development of post-treatment recycling of small-scale decentralized sewage treatment projects in my country is slow
