Diphase integrated multi-gradation internal circulation anaerobic bioreactor

Abstract

This invention relates to a two-phase integrated, multi-layered and internal-circulation anaerobic biological reactor. It is composed of: an upper inner casing, a middle inner casing and alower inner casing, a 1st gas-liquid separation reflecting plate, a 2nd reflecting plate, a 1st gas-isolation guiding plate, a 2nd gas-isolation guiding plate, an upper agitator, a lower agitator, liquid distributor and solid-liquid separator. Due to the equipped multiple inner circulation it makes the liquid being of fluidization condition, the anaerobic reaction is better than that of prior art method. This invention has advantages of: low area occupation, high load rate, high resistance of shock load, high efficiency, stable treatment, convenient operation, low operation cost, full sealed system of reactor, no bad odour, quick starting, short period of establishment, being suitable for the treatment of waste-water, waste-matter and waste-sludge in size of large, medium or small scale.

Description

technical field [0001] The invention relates to an organic waste water, waste and sludge treatment equipment, especially a two-phase integrated multi-level internal circulation anaerobic bioreactor Background technique [0002] With the rapid development of industrial production, the treatment technology of organic waste, especially wastewater, has attracted widespread attention. At present, there are two types of biological treatment methods for various organic wastes: anaerobic and aerobic. Anaerobic treatment is an important technology for the harmless treatment of waste. Compared with aerobic biological treatment, anaerobic biological treatment has more advantages, including low sludge yield, low energy consumption, energy recovery, etc. [0003] At present, in the anaerobic biological treatment method, conventional organic waste and wastewater anaerobic treatment equipment include UASB anaerobic reactor, anaerobic biological filter and so on. The above-mentioned vario...

AI Technical Summary

Problems solved by technology

The above-mentioned various equipments have obvious deficiencies: large floor area, unstable volume load, easy clogging and aging of filter material, low availability of by-products, and need for additional reflux

However, this process requires a lot of equipment. For small and medium-sized wastewater treatment projects, due to the variety of equipment, complicated operation and management, and relatively large heat loss of equipment, the treatment efficiency is reduced and the project cost is high.
