Integrated pulse inner cycle anaerobic reaction device

Abstract

The invention discloses an integrated pulse inner cycle anaerobic reaction device, and relates to the technical field of anaerobic biological treatment. The device structurally comprises a reactor tank body, a pulse generator, a gas-moisture separation tank and the like. As a primary guide plate and a secondary guide plate are additionally arranged, the water flow uniformity of the reactor is improved. According to different shapes of reactors, the guide plates are rhombic or rhombic circular so as to guide part of sewage to a pulse dead angle area and generate an impact effect by pulse, so that mud and water are adequately mixed. In addition, as the primary guide plate is arranged in the middle of the reactor tank body to form the bottleneck effect, the local ascending velocity of the reactor tank body is increased to form different velocities in vertical direction of the reactor tank body, so as to further enhance the mixing uniformity. A pulse water distributor is designed for better solving the problem that the anaerobic reactor is rancid due to short-circuit of water flow in the reactor.

Description

technical field [0001] The present application relates to the technical field of anaerobic biological treatment, in particular to an integrated pulse internal circulation anaerobic reaction device. Background technique [0002] Anaerobic biological treatment technology (AD, Anaerobic Digestion) has been widely concerned and valued by people because of its outstanding advantages such as high load, low energy consumption, low cost and recyclable energy carrier methane, and has broad application prospects at home and abroad. [0003] In the development of anaerobic biological treatment technology, the reactor is one of the fastest growing fields. The first-generation anaerobic reactors represented by anaerobic digesters cannot separate the hydraulic retention time (HTR) from the sludge retention time (SRT), so the residence time of wastewater treatment needs at least 20-30d, and the treatment efficiency is extremely low . Due to the slow growth of anaerobic microorganisms and...

AI Technical Summary

Problems solved by technology

The application of the existing anaerobic technology in my country's domestic market is generally unsatisfactory, and there are many deficiencies, such as large power consumption, high cost, large project scale, difficult operation, difficult maintenance, difficult The maintenance and decomposition process takes too long, and the problem cannot be solved at one time, etc.

Many domestic enterprises have taken measures and have specialized equipment for sewage discharge, and some have mastered anaerobic technology, but they are not satisfactory in terms of carbon reduction and energy saving. The common problems are: the water flow in the reactor is uneven, and the waste water is not easy to mix The anaerobic sludge is fully mixed and contacted, and the removal rate of sewage BOD is low; the hydraulic load is low, the influent flow rate is low, and it is difficult for the sewage to stir the anaerobic sludge for mixed contact, resulting in a decrease in treatment efficiency
