Abstract
The invention discloses a complete equipment of sludge resource disposal for an urban sewage treatment plant, which includes a pre-mixer, a bioreactor, a delivery device, a heating and ventilation device and a control system. The sludge water content from the sewage treatment plant is around 80 percent following mechanical dewatering treatment; the wet sludge is stored in a sludge tank and delivered then into the pre-mixer together with auxiliary materials via a screw conveyor; Following mixing and air bubble elimination, the uniform mixture is lifted to the multi-level structured bioreactor provided with the heating and ventilation device, where the sludge goes through microbial fermentation under aerobic conditions for approximate 100 hours and the water content of the output sludge is low than 30 percent. The equipment has good adaptability, low energy consumption, high safety and simple operations, by which the high-quality finished products can be produced to allow the downstream processing in manufacturing compound fertilizer and various soil amendments. The invention can be applied for sludge disposal in small and middle-sized urban sewage treatment plants with a view to sludge reduction, stabilization, innocence and resource recovery.
Description
It is relevant that technical field patent of the present invention relates to the sludge disposal equipment that the municipal sewage plant produces.Along with the popularizing of sewage treatment facility, the raising of processing rate and the in-depth of degree of treatment, the sewage plant sludge generation will have bigger growth, and the secondary pollution problem that causes thus can not be ignored.
Stable and the dehydration of background technology sludge from wastewater treatment plant (generally dewater to water ratio reach 70%～80%) is called the processing of mud; Compost, landfill, mummification and heat treated and final utilization the with mud are called the disposal of mud.Surpass agricultural standards as hazardous and noxious substances in the dewatered sludge, just must consider sanitary landfill and sludge anhydration burning technology.Present prior art situation:
1, this method is stablized in anaerobic digestion has a small amount of utilization at large-scale wastewater treatment plant at present, but because the slaking apparatus complex process, one-time investment is big, moves difficult.Anaerobic sludge digestion and biogas utilization installation cost account for about 30% of sewage work's investment and running cost, and need importing technology and equipment mostly.From investigating the actual motion of having built digester, have only minority to get a desired effect.Mud can not satisfy the health needs after anaerobic digestion simultaneously, also is unfavorable for the requirement of follow-up incineration disposal.
2, direct reuse farmland mud is the method that many Sewage Plant adopt through suitably concentrating, being transported to suburbs after the dehydration or the rural area is fertile as farming.But hazardous and noxious substances surpasses agricultural standards in the dewatered sludge, and possible contaminated land causes irreversible arable land to degenerate; Farmland fertilization has seasonality simultaneously, and when not needing sludge, Sewage Plant can completely be trouble by mud.If defrayment pulls away mud, and pays no attention to its whereabouts, be certain to cause secondary pollution.
3, can directly dispose after this traditional method of traditional sludge compost and aerobic fermentation is handled, but because this traditional technology requires fermentation time long, floor space is big, and the odor pollution environment, simultaneously to airborne release greenhouse gases (be carbonic acid gas 20 times).
4, the sanitary landfill sewage plant sludge is transported to city refuse landfill and disposes in the lump, there are two practical problemss in this: the one, and refuse landfill belongs to the management of environmental sanitation office, and sewage plant sludge belongs to the municipal systems management, and sewage plant sludge is admitted in the design refuse landfill working life and the not consideration of layouting; The 2nd, transport the mud of refuse landfill to, require water ratio to be not more than 30%, and the dewatered sludge water ratio about 80% of Sewage Plant is difficult for rolling landfill, directly landfill then can make landfill yard scrap in advance.
The drying and incineration Design of device of 5, mummification, burning sludge, the ratio sewage complex treatment process many; The municipal sewage sludge water ratio is up to 80% simultaneously, and this part moisture content is difficult to burn, and running cost is very high.
Summary of the invention the object of the present invention is to provide a kind of efficient, practical recycling sludge to be manipulated so complete equipment.With mud is prerequisite as agricultural fertilizer and greening with soil finally, it is big to solve ground, the station area that exists in present sludge composting and the aerobic fermentation process with equipment aerobic fermentation technology, convection drying working cost height and the key technical problem that also needs to carry out follow-up deep processing shaping, realized mud handle by fermentation one the step finish, solved small and medium cities sludge of sewage treatment plant disposal concerns.
This equipment moves in safety temperature, all-sealed structure, and it includes premixer, bio-reactor, e Foerderanlage, heat supply and ventilation plant and complete machine automatic control system.Mud after the dehydration is placed in the storage mud jar, delivers in the premixer in auxiliary material by screw conveyor, and premixer is that aeration type stirs, and main body is the stainless steel pyramidal structure.This structure agitator stirs the comprehensive continuous circulation of material by two opposite stirring tanks of sense of rotation, and circulation ability is strong, shears gentle.Material has bigger flow circuit amount in mixing tank, can smash air bubble during the material thorough mixing, makes fining air bubbles, improves the rate of mass transfer of gas-liquid.The aerobic fermentation bio-reactor is the stainless steel multilayer structure design, every layer is provided with one group of oar formula stirring tank, and maximum speed of revolution is 0.27 rev/min, can make the solids in the material keep suspended state during stirring, increase the residence time of gas in material, effectively utilize airborne oxygen; Be provided with two cover transmission mechanisms, every cover transmission apparatus is provided with independent control unit, every layer of residence time of material 24 hours.Be provided with oily heating system, hot-fluid introduced respectively axle, blade of the dryer shell of hollow and rotation etc. all with device that mud contacts in, heating unit is arranged in reactor-side basifacial and bottom, and independently Controlling System can heat different equipment respectively.Mud moisture content under the effect of heating system obtains evaporation, activate the biological inoculum in the mud simultaneously, make mud under aerobic environment, carry out microbial fermentation, the temperature of mud presents fast rise, stable, slow downward trend, in about 100 hours of the sludge fermentation cycle in the entire equipment, the outlet moisture percentage in sewage sludge is less than 30%.Static pressure variation, air quantity variation and the interior air-flow of reactor of considering pipeline distribute, and adopt independent air intake, and the merging air discharge structure discharges after the expellant gas process deodorizing device processes.
