Description
Technical field
The utility model belongs to field of environment protection, a kind of city sewage sludge reclamation treatment system of specific design
Technical background
Municipal sludge is the by product that sewage work produces in sewage treatment process, and calculate with water ratio 97%, volume accounts for 0.3% ~ 0.5% for the treatment of capacity of disposing of sewage.In recent years, in succession build up and put into operation along with sewage work in all parts of the country, the turnout of municipal sludge also grows with each passing day.Municipal sludge water ratio is high, perishable, there is strong odor, containing a large amount of organism, also have the objectionable constituent such as the organic pollutant of the heavy metals such as a large amount of pathogenic bacterias, parasite and copper, arsenic, lead, zinc, aluminium, mercury and difficult degradation simultaneously, therefore, carrying out municipal sludge stabilization, innoxious, recycling treatment, is the important development direction of future city sludge treatment.
At present, the generation of mud is large, the process of mud is disposed and is relatively lagged behind, sludge stabilization rate is low, harmless treatment rate is not high, will certainly limit the whole sewage treatment industry of China and develop in a healthy way, undressed municipal sludge Land_use change, soil compaction can be caused, Plant death, the problems such as the accumulation of heavy metal on food chain, cause serious environment and hygienic risk; The municipal sludge landfill disposal extensively adopted at present, floor space is large, and along with the scarcity day by day of land resources, its application is restricted day by day; And adopt urban sludge earthworm process at present, recycling treatment that anaerobically fermenting process can not realize municipal sludge up hill and dale, and the problem such as municipal sludge aerobic compost treatment technology still exists part compost heavy metals exceeding standard, poor processing effect.How to eliminate or to reduce the problem that in urban sewage sludge compost, portioned product heavy metal content exceeds standard, having become the technology focus that current composting technology needs to solve.
Summary of the invention
In order to thoroughly realize the minimizing of municipal sludge, innoxious, recycling treatment, the utility model provides a kind of city sewage sludge reclamation treatment system, solves weak point of the prior art.
The utility model specifically adopts following technical scheme:
A kind of city sewage sludge reclamation treatment system, it is characterized in that, comprise shearing afforestation garbage grinder of connecting successively, trilateral long ridge aerobic compost reactor, trilateral long ridge secondary aerobic compost reactor, cylinder round sifter, trilateral long ridge aerobic compost reactor is connected with microbiobacterial agent sprinker, trilateral long ridge secondary aerobic compost reactor is piled be connected with microbiobacterial agent sprinker, vermiculture process biology respectively, and vermiculture process biology heap is connected with full-mixing type anaerobic fermentor tank.
Device of the present utility model has the risk reducing Heavy Metal Pollution in Sludge, thoroughly realize the advantage of city sewage sludge reclamation process, there is significant environmental benefit, municipal sludge is converted into the organic fertilizer meeting Ministry of Agriculture's fertilizer standard, simultaneously, reclaim biomass energy---biogas, organic fertilizer and earthworm, there is significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the utility model FB(flow block);
In figure, 1 be full-mixing type anaerobic fermentor tank, 2 for vermiculture process biology heap, 3 be shearing afforestation garbage grinder, 4 be trilateral long ridge aerobic compost reactor, 5 be trilateral long ridge secondary aerobic compost reactor, 6 be cylinder round sifter, 7 for microbiobacterial agent sprinker.
Embodiment
As shown in Figure 1, a kind of city sewage sludge reclamation treatment system, comprise shearing afforestation garbage grinder 3 of connecting successively, trilateral long ridge aerobic compost reactor 4, trilateral long ridge secondary aerobic fermentation reactor 5, cylinder round sifter 6, trilateral long ridge aerobic compost reactor 4 is connected with microbiobacterial agent sprinker 7, trilateral long ridge secondary aerobic compost reactor 5 is piled 2 be connected with microbiobacterial agent sprinker 7, vermiculture process biology respectively, and vermiculture process biology heap 2 is connected with full-mixing type anaerobic fermentor tank 1.
Its working process is: first municipal sludge carries out Wuli-Shili-Renli system approach analysis, for heavy metal content exceed standard higher than " in agricultural sludge pollutant catabolic gene standard (GB4284-84) " more than 20% municipal sludge, drop in 1, carry out anaerobically fermenting process, not only recyclable biomass energy---biogas, anaerobically fermenting has the effect of stabilization to the heavy metal in municipal sludge simultaneously.The complete hybrid anaerobic fermentation technology adopted in present embodiment, for the known technology of field of environment engineering, difference place is to adopt sludge pump that the natural pond liquid after output biogas and natural pond slag are sent to vermiculture process biology heap by pipeline, cloth is sprinkled upon the surface of vermiculture process biology heap equably, allow it slowly infiltrate in heap, regulate the humidity of vermiculture process biology heap.For the mud that other heavy metal content exceeds standard, carry out 2 process, earthworm with organic pollutant in mud for food, while the breeding of promotion own growth, make municipal sludge realize stabilization, minimizing process, earthworm is in process of growth simultaneously, be enriched the heavy metal in mud in a large number, in the latter stage of its growth, the earthworm being enriched heavy metal is reclaimed, the most of heavy metal in mud just can be realized to have extracted through the method for this biomagnification.Municipal sludge, after breeding earthworm, just becomes earthworm copropel, becomes the raw material of good organic compost.The natural pond slag, the natural pond liquid that produce in 1, be sprayed to 2 heap bodies stage by stage, except the growing environment regulating earthworm, promote outside the growth and reproduction of earthworm, outstanding effect is that the heavy metal in natural pond slag, natural pond liquid more homogeneity is distributed in vermiculture process biology heap with liquid or fluid, avoid partial sludge because of heavy metal content too high, affect the quality fluctuation problem of final fertilizer product.
Heavy metal content is met to the municipal sludge of " in agricultural sludge pollutant catabolic gene standard (GB4284-84) ", with the garden wastes processed through 3, carry out abundant mix and blend, carry out 4 process, and regularly utilize 7 sprinkling microbiobacterial agents, to accelerate aerobic compost processing efficiency, improve compost temperature, turning is carried out, enhanced oxygen blowing in composting process.The trilateral long ridge aerobic compost reactor of 4 process, the agronomy expert of general China is referred to as bar buttress formula compost heap, be characterized in the compost of long strip shape, we are called trilateral long ridge compost, both the feature of long strip shape compost had been highlighted, more enter again the feature that is portrayed the section shape triangular in shape in its transverse section, more meet the general formulation in Europe.After 4 process, carry on 5 process, be mixed with the earthworm copropel that process 2 obtains in process, and utilize 7 sprinkling microbiobacterial agents, warm aerobic fermentation in realization, organic pollutant content in further reduction mixture, after abundant compost fermentation, carry out 6 screening process, remove foreign material, after qualified after testing, can pack, dispatch from the factory.
The microbiobacterial agent that 4 process and 5 process are sprayed, for obtaining the microbiobacterial agent product that The Ministry of Agriculture of the People's Republic of China, MOA formally registers.In this embodiment, 4 process adopt microorganism fertilizer (2006) accurate word (0304) number product, adopt microorganism fertilizer (2000) accurate word (0005) number product in 5 process.Respectively by the specification sheets water of product rush rare after, load in 7 microbiobacterial agent sprinkers, be sprayed in aerobic compost reactor.
