Abstract
The invention relates to a treatment method for biochemical sludge. The method comprises the following steps: setting up an aerator pipe and a biological nest frame in a sludge reaction tank; binding a plurality of biological nests to the biological nest frame in interval; inputting the biochemical sludge which is 90% of the reaction tank and has 15-40 g/L of silt content to the sludge reaction tank; introducing air to the sludge reaction tank through the aerator pipe to enable the biochemical sludge in the tank to be stirred and aerated completely; spreading a microbial sewage sludge treating agent to the sludge reaction tank according to the dose of 1-1.5 g/cubic meter (sludge) per day to enable the biochemical sludge to take reaction for 48-60 hours in the sludge reaction tank; keeping the pH value of the biochemical sludge in the sludge reaction tank at 7-9; opening a sewage sludge output pipe to convey the sludge water containing microorganism to a sludge conversion tank every two hours within the reaction time, wherein the discharge of the sludge water every time is 20% of the amount of the biochemical sludge in the sludge reaction tank; after discharging, inputting the same amount of biochemical sludge into the sludge reaction tank to continue reaction; supplementing the sewage sludge treating agent to the sludge water which is discharged in the sludge conversion tank according to the dose of 0.5 g/cubic (sludge) meter per day, and then standing; and further gasifying the sludge water to convert clear water, and respectively discharging the clear water at the upper layer and the sludge at the lower layer.
Description
Technical field
The present invention relates to a kind of processing method of sewage sludge, particularly a kind of processing method of the biochemical sludge that the biochemical sludge in city sewage and sludge or trade effluent mud place in process is cut down.
Background technology
To in city sewage and sludge or trade effluent mud place, at present, after general employing first processes the inorganic part in sewage sludge, again the sewage sludge (biochemical sludge) of organic component is processed, and to the mode that the process of this biochemical sludge adopts mostly be: biochemical sludge is sent in collection mud sump or conversion pool through pipeline and is stored, adding flocculant makes it precipitate, the drying sludge of precipitation, compacting are carried out mummification place and buried, is transported to by the mud vehicle after mummification and burn field or landfill yard carries out burning or landfill.But the mud after drying and other treatment adopts burning to release toxic and harmful, produces the pollution to air; Landfill is adopted to the mud after drying and other treatment, not only occupies non-renewable (soil) resource, and expend the energy, and the underground water seepage produced due to landfill material will cause the secondary pollution of soil, underground water, is unfavorable for environmental protection.And other simply add the method for microorganism formulation process, owing to lacking suitable environment and fit system, not that less effective acts on exactly can not lasting stability, really do not form the condition of industrial applications.
Summary of the invention
The object of the invention is to for overcoming the deficiencies in the prior art, a kind of processing method of biochemical sludge is provided, it is at the non-renewable social resources of not land occupation etc., the not consume fuel energy, do not use chemicals, under not producing the prerequisite of secondary pollution, realize abatement completely and the harmless treatment of biochemical sludge
Present invention employs following technical scheme: a kind of processing method of biochemical sludge, is characterized in that: 1), in sludge reaction pond, set up the multi-lamellar biological nest frame of aeration tube and steel construction, at each layer multiple biological nest of interval bind respectively of biological nest frame; 2), in sludge reaction pond, its 90% cubical content is inputted by sewage sludge input channel, clay content is the biochemical sludge of the organic component of 15-40g/L, in sludge reaction pond, send air through aeration tube, fully stir aeration, by 1-1.5g/m to make the biochemical sludge in pond
3the use amount of (mud) day is sprinkled into microorganism sewage water sludge treating agent in sludge reaction pond, makes biochemical sludge react 48-60 hour in sludge reaction pond, and the pH value keeping biochemical sludge in sludge reaction pond is therebetween between 7-9; 3) within the previous reaction time, once open sewage sludge output channel every 12 hours in mud conversion pool, carry sludge water with microorganism, the discharge capacity of each sludge water is 20% of biochemical sludge amount in sludge reaction pond, opens the biochemical sludge continuation reaction that sewage sludge input channel inputs equivalent in sludge reaction pond after discharge; 4) sludge water in mud conversion pool, is entered by 0.5g/m
3the use amount of (mud) day leaves standstill after adding sewage sludge inorganic agent, and sludge water gasifies further and converts clear water and mud to, and the excessive mud that upper strata clear water and lower floor accumulate is discharged respectively.
By the processing method of biochemical sludge provided by the invention, due to be provided with in sludge reaction pond biological nest frame and on biological nest, aeration tube, when performing process, microorganism sewage water sludge treating agent is sprinkled in sludge reaction pond, through aeration tube input air, aeration is carried out to biochemical sewage mud, in sludge reaction pond, because each biological nest is the orbicule that multiple central authorities curved fins with holes combines, symbiosis for microorganism provides good implantation condition, make biological nest outside be conducive to microorganism aerobic flora growth to assemble, biological nest inside is conducive to microbiological anaerobic flora growth and assembles, the muddy water flowing of appropriateness can be formed again inside and outside biological nest, due to microorganism, to have volume little, surface area is large, the feature that reproductive capacity is strong, nutrient can be obtained and degrade simultaneously and change the organic substance in biochemical sludge from biochemical sludge, aerobic flora and anaerobic bacteria flora are formed jointly microbial ecosystem that one has good mud consumption, entering the sludge water with microorganism in mud conversion pool, continue to cut down biochemical sludge in the effect of fungal component, in the processing procedure of whole biochemical sludge, work in coordination with through various microorganism and play a role, whole or the large portion of insoluble organic in mud can be made to be converted into nontoxic biogas, hydrogen, the stable materials such as carbon dioxide, thus realize biochemical sludge decrement and innoxious object.The present invention does not take non-renewable social resources, particularly precious land resource and fuel; Whole process is completely innoxious, there will not be underground water seepage and contaminated land resource etc.; Microbial reaction is gentle, does not substantially have potential safety hazard; The operating cost of biochemical sludge process is lower; Owing to being to the decrement on the source in sludge handling process, save the consumption such as the manpower in the reprocessing processes such as mummification, equipment, power, transport and flocculant; Industrial sludge environmental effect part being decided to be to danger wastes is more obvious.
Detailed description of the invention
