Novel anaerobic reactor based on UASB and treatment system

Abstract

The invention discloses a novel anaerobic reactor based on UASB and a treatment system. The novel anaerobic reactor comprises a novel anaerobic reactor body, a degassing pool, a precipitation pool andan automatic monitoring system, wherein an anaerobic reactor control system realizes fully automatic control through information such as temperature and flow rate; the anaerobic reactor body and thedegassing precipitation pool consist of a water inlet pipe, water distribution pipes, a tank body, a circulation system, a corrugated board separator, an arch top air seal, a water sealing tank, a siphon water outlet system and a degassing precipitation pool. The bottom water distribution pipes are used for water distribution; the uniform water inlet at the bottom can be effectively ensured; the sludge deposition probability due to nonuniform water distribution is reduced; a low-region circulation system is added, so that the low-region high flow rate is realized; the mass transfer effect is effectively improved; contaminants and particle mud are in sufficient contact; the operation efficiency of the reactor is enhanced; a gas collection mode of a inclined plate and the arch top air seal is used, so that the investment cost is reduced; meanwhile, the marsh gas collection efficiency is improved; through the arrangement of the degassing precipitation pool, lost sludge in the anaerobic reactor can be supplemented, and the stable operation is ensured.

Description

technical field [0001] The invention relates to a novel anaerobic reactor and a treatment system based on UASB, specifically in the technical field of environmental protection equipment. Background technique [0002] UASB is a sewage treatment equipment that uses the degradation of anaerobic microorganisms to purify the organic substances in sewage under anaerobic conditions. Anaerobic biological treatment of wastewater refers to the process of converting various complex organic molecules in wastewater into methane, carbon dioxide and other substances through the action of anaerobic microorganisms under the condition of no molecular oxygen, which is called anaerobic digestion. Anaerobic reactors have the advantages of low energy consumption, high organic load, and biogas energy generation, and are widely used. [0003] At present, the load of UASB reactor is low during operation, the impact resistance is low, and the rising flow rate is small. It has high requirements for t...
