Organic matter high-load anaerobic digestion treatment system

Abstract

The invention discloses an organic matter high-load anaerobic digestion treatment system which comprises an anaerobic reactor, the top of the anaerobic reactor is sealed by a flexible membrane with a reserved space, and the sealed space of the anaerobic reactor comprises an anaerobic reaction area below the liquid level and a biogas buffer area above the liquid level. The biogas buffer area is provided with a biogas outlet, and the anaerobic reaction area is provided with a jet stirring device in a matched manner. The jet stirring device is arranged in the anaerobic reaction area in a matched mode, high-strength and completely-mixed stirring is carried out on the anaerobic reaction area, the problems of scum generation, hardening and the like in the anaerobic reaction area can be effectively avoided, and the adverse effect of grease substances in fed materials on an anaerobic system can be effectively controlled and eliminated. Therefore, the technical effects that the overall operation efficiency of the anaerobic digestion system is greatly improved, and long-term stable operation can be realized under the environment of higher organic load and high oil content are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-load anaerobic digestion treatment system for organic matter. Background technique [0002] Anaerobic digestion is a common treatment process for wastewater containing biodegradable organic matter and high-solid slurry. The treatment process is to use anaerobic microorganisms in the system to complete the transformation and metabolism of organic matter. Due to the relatively slow proliferation of anaerobic bacteria, the number of anaerobic microbial flora in the reactor has become one of the key factors restricting the efficiency of the anaerobic digestion treatment system. Therefore, how to increase the number of anaerobic bacteria in the reactor to improve the efficiency of the anaerobic system Treatment capacity is a hot spot in the current research on the improvement and optimization of anaerobic process. Because the existing two-phase solid...

AI Technical Summary

Problems solved by technology

Because the existing two-phase solid-liquid separation of anaerobic digestion treatment technology usually adopts the method of gravity separation, there are problems such as low separation efficiency, large floor space, and difficulty in odor collection, especially for difficult-to-handle organic materials with high solid content and oil content. For solid waste slurry, fully mixed anaerobic reactors are mostly used, which have very limited means of increasing the concentration of activated sludge in the stable system and avoiding the impact of oil on the anaerobic system, which makes this type of anaerobic reactor Oxygen digestion treatment technology has limitations in dealing with high processing load requirements, high solid content, high oil content organic wastewater and anaerobic digestion treatment of organic slurry
