Abstract
The invention discloses a composite conditioner for preparing a sludge compost and application thereof. The composite conditioner for preparing the sludge compost is combined by an agricultural waste fermentation product and non-metallic ore powder in a volume ratio of 1-10:5-1, wherein the agricultural waste fermentation product is prepared by performing direct pile fermentation on one or a mixture of more of sawdust, barks, rice hulls, straw and bagasse or adding zymophyte for aerobic fermentation; and the non-metallic ore powder is one or more of pearlite, vermiculite, zeolite, medical stone and sepiolite with the grain size of smaller than 0.5cm. The composite conditioner can quickly degrade cellulose, shorten the sludge fermentation period to 7-15 days, improve the C/N ratio of the sludge and reduce the diffused odor, also can adjust the pH value of mixed materials, is more favorable for the growth of microorganisms, and can improve fertilizer efficiency and improve the soil.
Description
Technical field
The present invention relates to a kind of composite conditioner for preparing sludge composting.
Background technology
Produce a large amount of mud in municipal sewage plant's treating processes, it contains a large amount of organism, abundant nutrition such as nitrogen phosphorus, pathogenic bacterium and pathogenic bacteria etc., and any discharging meeting that does not add processing causes serious pollution to environment.Along with further developing of urbanization, new sewage work will constantly set up, and will produce more substantial mud, and the problem of outlet that solves so a large amount of mud has become the task of top priority of sewage disposal.The method of sludge compostingization is the more satisfactory method for sludge treatment that sludge reduction, innoxious, stabilization and resource utilization are combined together.Both made full use of and contained the required nitrogen of growth and development of plants, phosphorus, potassium in the mud in a large number and keep various trace elements that plant normal growth grows and the organic matter that can improve Soil structure, provided good prospect for the handling problems that solves mud again.Lump easily but moisture percentage in sewage sludge height, porosity are low, added flocculation agent in the dehydration, be unfavorable for ventilation oxygen-supplying in the composting process, and the C/N of mud is than low, make nitrogen in the waste with NH
3Formation volatilization loss, give out stink, be unfavorable for microbial growth, need add amendment during compost.Traditional amendment is directly to add wood chip, sawdust, bark, rice husk, stalk, bagasse, but difficult degradation polymer substance content height such as this its Mierocrystalline cellulose of class amendment, hemicellulose, pectin, degraded slowly, the sludge fermentation cycle reached about 30 ~ 50 days, and the degradation of the supported hole gap structure behind the stack retting can't be carried out structural adjustment to compost material.
Summary of the invention
The object of the present invention is to provide a kind of composite conditioner for preparing sludge composting.To realize that cellulose degradation is accelerated, shortened in the sludge fermentation cycle; Simultaneously can further improve venting capability, be more conducive to microbial growth; Improve mud C/N ratio, also reduce the stink that distributes; And can regulate the pH value of mixture, increase micronutrient levels in the sludge composting; Improve the improvement of fertilizer efficiency, realization soil.
Composite conditioner of the present invention is to be that 1 ~ 10:5 ~ 1 combines by agricultural waste fermentation product and nonmetalliferous ore stone powder according to volume ratio, and described agricultural waste fermentation product is through direct pile fermentation or add the zymophyte aerobic fermentation and form by one or more the mixture in wood chip, sawdust, bark, rice husk, stalk or the bagasse; Described non-metallic ore is a particle diameter less than in perlite, vermiculite, zeolite, medical stone or the sepiolite of 0.5cm one or more.
Described zymophyte is to be according to mass percent by aspergillus niger, viride, aspergillus oryzae: the mixed strains that aspergillus niger 30 ~ 60, viride 30 ~ 50, aspergillus oryzae 10 ~ 20 constitute.
Described direct pile fermentation is that agricultural wastes earlier are crushed to particle diameter through pulverizer is 0.2 ~ 2cm, spraying moisture makes water ratio reach 30 ~ 60% of mass percent, be piled into the bar buttress of 1.5 ~ 3.5m again, control thermophilic fermentation temperature is 55 ~ 75 ℃, 2 ~ 3d turns over buttress once, and pile fermentation is 15 ~ 30 days altogether.
Described adding zymophyte pile fermentation is that agricultural wastes earlier are crushed to particle diameter through pulverizer is 0.2 ~ 2cm, spraying moisture makes water ratio reach 30 ~ 60% of mass percent, the mixed fermentation bacterial classification that adds mass percent 0.5 ~ 5% again mixes, be piled into the bar buttress of 0.3 ~ 1m again, 30 ~ 45 ℃ of controlled temperature, turn over buttress every day 1 ~ 3 time, aerobic fermentation is 3 ~ 7 days altogether.
Composite conditioner may further comprise the steps in the application of preparation sludge composting:
(1) mud of water ratio less than mass percent 80% is mixed with the mass ratio of composite conditioner by 1:0.1 ~ 3, make its carbon-nitrogen ratio between 20:1 ~ 30:1;
(2) bar of mixture being piled into height 1m ~ 2m according to bar buttress formula or trough type fermentation is piled up neatly or fluting; Every cubic metre of fermentation materials feeds 0.05 ~ 0.2m
3The wind of/min, fermenting process adopt stack turner 2 ~ 3d to turn over buttress once, controlled temperature and air permeability; Overall fermentation time 7 ~ 15d; Thermophilic fermentation 5 ~ 7d wherein, the temperature of control thermophilic fermentation is 55 ~ 65 ℃.Fermentation plant adopts air extractor, fermentation odor is evacuated to the foul smell treatment system handles.
The present invention adopts agricultural waste fermentation product and non-metallic ore powder combinations to form, and agricultural waste fermentation product can make cellulose degradation accelerate behind the fermentation stack retting, makes the sludge fermentation cycle shorten to 7 ~ 15d; Improve mud C/N ratio, also reduce the stink that distributes; And the non-metallic ore powder splendid particulate matter that is air permeability can not only be regulated the performance of ventilating of sludge fermentation, also can regulate the pH value of mixture, is more conducive to microbial growth; Its micronutrient levels is abundant, itself also is good soil improvement agent, thereby improves the improvement of fertilizer efficiency, realization soil.
