Description
Technical field
The present invention relates to field of sludge treatment, a kind of method that mud dry distilling becomes charcoal.
Background technology
Along with industrialization, the quickening of urbanization process, the sludge quantity of sewage treatment plant is sharply increasing accordingly, many lake, pond, shallow lake, the mud in river course, the industrial sludge that industrial system produces all brings great environmental problem, the most safely and effectively process mud, a great problem urgently to be resolved hurrily during becoming industrialization, Development of Urbanization.
At present method for sludge treatment mainly has a three major types: burns, fill, recycling; current external commonly used burning and landfill; but owing to incinerating method investment is huge, cost is high; the most domestic few people use this kind of technique; current domestic commonly used be landfill; but on the one hand landfill needs to take the land resource of preciousness; on the other hand surrounding and underground water source can be polluted; this Treatment of Sludge mode is unfavorable for protecting urban ecological environment, and the method for recycling is the optimization process method advocated both at home and abroad.
Sludge treatment is the important ring in sewage disposal process, of equal importance with sewage disposal, the quality of Treatment of Sludge is one of key factor affecting environmental quality, owing to the water content in mud is up to 80-85%, if only mud being carried out simple landfill stabilization, the sewage of nearly 50% in mud is again to reenter in runoff, form secondary pollution, so to change the idea of " the light mud of heavy water " in sewage disposal in the past, the quality of sludge treatment is to embody an important performance assessment criteria of city environmental quality management level.
According to statistics, municipal sewage plant's quantity that China runs is more than 1418, sewage load is more than 8400 ton day, the annual whole nation produces mud (80-85% moisture content) 1600-2000 ten thousand tons, and increase more than 10% with annual, the huge financial deficits existed between actual production and the landfill storage capacity that can dispose of mud, cause a part of municipal sludge to have nowhere to go and the difficult situation that can not properly be disposed, therefore, how to dispose municipal sludge, it is increasingly becoming the hot issue of municipal administration concern, the contradiction of yield and storage capacity also becomes to become increasingly conspicuous, the problem of outlet solving mud is extremely urgent.
Summary of the invention
It is an object of the invention to provide and a kind of solve problem of environmental pollution, create the mud dry distilling method that becomes charcoal of new forms of energy, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of method that mud dry distilling becomes charcoal, comprise the following steps: S1, the reception of mud, mud car supports factory's weighbridge metering outdoors and draws code pound station, by automatic gauge draw code open single after enter factory's automatic type every smelly closed mud discharge zone, this discharge zone mainly includes the facilities such as mud splicing, conveying, storage bucket, discharge valve, fully meets the receipts arc manipulation part of sealed sludge transport vehicle；S2, sludge modification, in sewage treatment plant after one-time mechanical processed the mud of moisture content 80-85% be transported to mud centralized treatment plant by collecting vehicle, through weighbridge weigh after send into mud collecting pit.Mud after conditioning stirring, is delivered to sewage sludge storage pond in mud collecting pit.Sewage sludge storage pond is divided into 3, classify according to sludge components difference, domestic sludge enters 1 pond, industrial sludge enters 1 pond, poisonous and hazardous danger waste sludge enters 1 pond, the mud in each sewage sludge storage pond is transported in sludge modification reactor, by vacuum pump, sludge modification agent is added in sludge modification reactor, stir and within 5 minutes, make mud be modified reaction, wherein sludge modification reactor is sludge modification agent 3-5% according to mass percent, mud total amount 95-97%, sludge modification is after completion of the reaction, sludge modification reactor bottom valve automatically opens up, mud enters sewage sludge storage pond, underground, by sludge pump, mud is delivered to high-pressure extrusion dewatering system be dehydrated, all operations process completes in full-closed system, stenchless escaping；S3, sludge dewatering is dried, step S2 is collected modified mud sewage sludge storage pond, underground below modified-reaction device and is conveyed into high-pressure extrusion dewatering system by sludge pump, in high-pressure extrusion dewatering system, by high pressure sheet frame dewaterer, mud is carried out extrusion dehydration, make water content at the mud of 80-85%, reach, through extrusion dehydration, the dewatered sludge that water content is 40-50%, then add dewatered sludge powder, after mixing, enter sludge dewatering drying system；nullDewatered sludge after extrusion dehydration processes is while entering the main equipment dehydrate machine inlet of sludge dewatering drying system，Process the waste gas produced in sludge process and enter dehydrate machine inlet and inlet scoop together with natural air，Dewatered sludge and air is made to move in
