Description

A kind of sludge aerobic composting reactor
Technical field
The present invention relates to a kind of sludge composting technology, particularly relate to a kind of high water content sludge aerobic compost reactor that utilizes.
Background technology:
Mud (Sludge) is a kind of water ratio height (the liquid sludge water ratio can reach 99%), be the flow-like material of black or chocolate, generally the aggregate formed of the zoogloea that is formed by multiple microorganism and its adsorbed organic matter and inorganics.Mud is mainly derived from municipal sludge (Civil sludge, also be sewage sludge Sewage sludge,), pipe network mud, river and lake silt, industrial sludge, municipal sludge particularly, along with urbanization develops rapidly, urban sewage treatment system perfect, municipal sludge becomes a class mud of quantity maximum, becomes the key influence factor that urban construction and urban sewage treatment system are normally moved.Mud is the water ratio height not only, perishable, strong odor is arranged, also concentrated nutritive element, heavy metal and salt such as most organic matter, nitrogen phosphorus in the sewage, and a spot of pathogenic micro-organism and parasitic ovum etc., if not by rational treatment and disposal, these pollutents will directly enter environment, influence the appearance of the city, polluted-water and soil, even be detrimental to health.At present, the treatment and disposal of mud has become one of focus that environmental protection circle and municipal administration very pay close attention to.
Sludge compostingization is to rely on microorganisms such as bacterium in the mud, actinomycetes, fungi under certain artificial condition, controlledly promotes the Biochemical processes that biodegradable organism transforms to stable soil ulmin.Mud is through compost treatment, and volume generally can be reduced to the 50%-70% of original volume, and most of pathogenic bacteria and virus are killed.Mud is through behind the compost, the finished product that makes is called compost (Compost), it is that a class is brown, the very high bulk material of humus content as the peat, so be also referred to as " vegetable mould ", its stable in properties, can be used as soil improvement agent and carry out the soil utilization, realize the recycling of nutritive elements such as carbon source, nitrogen phosphorus in the mud.Therefore sludge compostingization is to realize sludge reduction, innoxious, stabilization and the comparatively effective a kind of treatment process of resource utilization.
Sludge compostingization can be divided into two kinds of anaerobic composting and aerobic composts by principle.Advantages such as aerobic compost is fast because of organism speed, and it is more abundant to degrade, and the compost cycle is short, and envrionment conditions is better and widespread use.Aerobic composting process is ripe relatively at present, according to having or not fermentation unit compositing system simply can be divided into open system and reactor assembly, the former can be divided into natural ventilation bar buttress formula system, passive air duct slats buttress system, forced ventilation static buttress system composting process again.The latter only adopts the box compost of simple type, and efficient is low, and level of automation is low.Because water content is high in the mud, it is extremely limited to adopt reactor assembly to carry out the quantity of compost, therefore, utilize mud to carry out the main employing open system of compost, promptly traditional artificial nature's composting mode, its composting process is as follows: the mud mummification of at first anhydrating, manually admix amendment, carry out aerobic fermentation, after the stage of becoming thoroughly decomposed, make composting production again.
Adopt traditional composting mode, yet cost is low, the floor area that takies is big, causes second environmental pollution easily; Adopt the box composting mode of simplification, still there is certain problem, mainly comprise: (1) moisture percentage in sewage sludge is too high, mud water ratio after processed generally still reaches 82%, and the suitable water ratio of sludge aerobic compost process is 50-65%, mud need pass through mummification, add a large amount of pre-treatment such as amendment before the compost, and this brings difficulty to practical engineering application, increases the expense of sludge composting; (2) there be the loss, particularly nitrogen of nutritions such as nitrogen, phosphorus in composting process, loses in a large number with volatilization and the filtrate loss form of N; (3) having certain heavy metal contamination in the mud, is one of key factor of restriction sludge composting soil utilization.
Summary of the invention
In view of existing these the three aspects restraining factors of mud, purpose of the present invention be exactly to design a kind of easy to use, the compost cost is low, the reactor of high water content sludge aerobic compost that environment is not polluted, and realize the aerobic compost of high water content sludge by this reactor, improve the sludge composting benefit, improve sludge composting product fertilizer efficiency, reduce sludge composting product heavy metal contamination risk.
