Description

A kind of modularization sludge hot hydrolysis treatment device and method

Technical field

The present invention relates to a kind of sludge treatment equipment and method, particularly about a kind of modularization sludge hot hydrolysis treatment device and method.

Along with improving constantly of sewage treatment capacity and wastewater treatment rate, the sludge yield of sewage work also increases thereupon.In the sewage disposal development course of China, although mud is one of important step in waste water processes, but because long-term understanding is not enough and ignore, the sludge disposal problem of municipal sewage plant of China is shelved for a long time, the development of sludge disposal is quite delayed, the secondary pollution problem day that mud causes is aobvious outstanding, the safe disposal problem of mud in the urgent need to address.Sludge treatment is the same with other solid waste process, all should follow minimizing, stabilization, innoxious principle, and realize recycling as far as possible.At present, the general technology of sludge treatment has mud sanitary landfill, sludge landfill characteristics, sludge composting, anaerobic sludge digestion, sludge incineration etc.Wherein, anaerobic sludge digestion can reclaim biogas, effectively kills pathogenic bacteria, realize the stabilization of mud and minimizing, and therefore anaerobic digestion techniques is used widely in countries in the world.

During anaerobic digestion, mud will experience hydrolysis, produce acid and methane phase three phases under the effect of microorganism.Because mud major part organism is in microorganism cells, and the natural cover for defense effect of microorganism wall and cytolemma, the speed that other lytic enzyme secreted by microorganism cells of living is hydrolyzed to this part organism is low, and therefore hydrolysis is the Control step of sludge anaerobic biochemical degradation.Because sludge hydrolytic speed is low, traditional anaerobic digestion exists that digestion rate is low, the residence time long deficiency such as (20 ~ 30d), processing efficiency low (clearance 30% ~ 40% of volatile solid VS).In recent years, people begin one's study can effective broken mud cell improve the physical chemistry preconditioning technique of sludge hydrolytic speed, to improve mud anaerobic digestion performance, improve processing efficiency, increase methane production.These technology comprise Mechanical Crushing, ultrasonic disruption, thermal hydrolysis, ferment treatment and acid, alkaline purification etc.Wherein, mud can realize the rapid solution of microorganism cells after thermal hydrolysis, significantly improves the mobility of mud, and the intermediate product formed after sludge hot hydrolysis is more suitable for as microbial growth matrix, improves the anaerobic digestion of mud.Because sludge hot hydrolysis needs pressure release before discharge, and the waste hot steam that pressure release is discharged takes away a large amount of heats, thus causing the heat of system to lose in a large number, the waste heat therefore improving sludge hot hydrolysis exhaust steam recycles the important subject that the high efficiente callback realizing energy is this field.
