AI Technical Summary

Technical Problem

Existing rural sewage treatment facilities suffer from poor ammonia nitrogen treatment performance, complex structures, and high operating costs. In particular, the sludge return ratio is difficult to control in small-scale facilities, resulting in high treatment costs.

Method used

An integrated biochemical device is adopted, including an inner cylinder and an outer cylinder to form the main body of the reactor. A sedimentation zone is formed between the inner and outer cylinders. An aeration system is constructed by combining an aerator and an air pipe to form an anoxic and aerobic coexistence zone. The secondary sedimentation tank and nitrification liquid return pump are eliminated. Oxygen and hybrid power are provided by a submersible jet aerator.

Benefits of technology

It achieves a simplified structure, saves space and investment costs, and reduces operating costs. Through innovations in the inner and outer cylinder design and the gas distribution system, it reduces the power consumption of the equipment and improves the ammonia nitrogen treatment effect.

Abstract

This invention provides an integrated biochemical device and an integrated biochemical system. The integrated biochemical device includes a reactor body, an inlet / outlet water system, an aeration system, and a sludge removal system. The reactor body includes an inner cylinder and an outer cylinder, which are interconnected. The inlet / outlet water system includes an inlet pipe and an outlet pipe; the outer side of the outer cylinder is connected to the inner side of the inner cylinder via the inlet pipe, and the inner side of the outer cylinder is connected to the outer side via the outlet pipe. The aeration system includes aerators and air pipes, with each air pipe connected to one aerator. The sludge removal system includes a sludge removal pipe. In this embodiment, the reactor body is constructed using the inner and outer cylinders, utilizing the gaps to form a sedimentation zone. The structure is simple, easy to operate and manage, and the integrated design significantly saves floor space and investment costs. The aeration system, constructed using aerators and air pipes, utilizes the inner cylinder to form a reaction zone, creating an anoxic and aerobic coexistence zone, which significantly saves electricity and reduces operating costs.
