Description
Technical field
The present invention relates to environmental protection technical field, particularly a kind of organic wastes such as excrement slag, changing food waste are converted into fertilizer, realize the method for reclaiming organic waste.
Background technology
Organic wastes such as excrement slag, changing food waste, excess sludge are to perplex people as environmental pollutant always; People have often ignored contains elements such as abundant organic matter and the needed nitrogen of crop growthing development, phosphorus, potassium in the organic wastes such as excrement slag, changing food waste, excess sludge, can become the composting material that is of value to agriculture prodn.Produce not only quality better of agricultural-food with compost, and can continue to improve Soil structure, more can digest a large amount of organic wastes that possibly cause environmental pollution.The compost method floor space of tradition farmers' is big, handles not thoroughly, and the foul smell that produces in the composting process is not easy to control; Cause atmospheric pollution equally; Can not continuous production, can only continue the present situation of a large amount of organic wastes of output in the time of can not tackling urbanization as farmers''s pattern on a small scale; Therefore needing to be resolved hurrily in environmental protection technical field, to produce compost large-scale production, serialization operation, floor space little for organic waste; Avoid secondary pollution, mechanizable treatment process to occur, therefore, the technician has designed different equipment and technology solves above-mentioned technical problem.
For example; In the prior art; Application number is 200510086403.3; The technical scheme that name is called the application for a patent for invention disclosure of " organic solid castoff compost treatment and biological deodorizing system and working method thereof " is: mix organic solid castoff and accept the mixing machine II from the amendment of being pulverized by kibbler I through handling equipment, connect with vertical forced ventilation composting device III through handling equipment; Vertical forced ventilation composting device III connects with the storehouse IV that becomes thoroughly decomposed through handling equipment, and the venting port of vertical forced ventilation composting device III connects through the inlet mouth of pipeline with the biological deodorizing reaction unit VI that has venting port; The storehouse IV that becomes thoroughly decomposed connects with sieve apparatus V through handling equipment; The discharging port of sieve apparatus V is divided into finished product material mouth and defective goods material mouth, and defective goods material mouth connects with mixing machine II through handling equipment.Employing time-temperature natural and mechanical combined ventilation mode.
Aforesaid method has partly solved the difficult problem of a large amount of organic castoff composts; But still there is the problem that can not adapt to a large amount of especially city organic castoff compost of continuous processing; And reduce artificial the intervention as far as possible, and make the operator avoid being in the abominable Working environment, ensure workers ' health.
Summary of the invention
In order to solve the technological deficiency that prior art exists; The method that the object of the present invention is to provide a kind of reclaiming organic waste to handle; It can accomplish scale production compost, serialization operation, floor space is little; But avoid secondary pollution mechanize production, reduce artificial the intervention, make organic castoff compost become more valuable commodity.
To achieve these goals, technical scheme of the present invention is:
The method that a kind of reclaiming organic waste is handled mainly comprises batching, conveying, compost, slaking and temperature control, ventilation, becomes fertile processing and foul smell treatment process, the steps include:
-batching: pretreated excrement slag and organic auxiliary material and aerobic bacterial classification sent in the batch mixing stirrer stir; Organic auxiliary material water ratio＜30%, particle diameter＜5mm, organic content＞85%; Batch mixing stirrer stirring velocity 6r/min-10r/min, mixture water ratio 50% ~ 65%;
-to carry: mixture is in worm conveyor is delivered to in-vessel composting system, and the outlet of batch mixing stirrer is connected through square tube with the import of worm conveyor, and material falls into the import of worm conveyor by deadweight;
-compost: have track on the in-vessel composting system bulkhead, stack turner is walked in orbit, and the mixture in the in-vessel composting system is with stack turner turning every day 1-2 times; Material turning evenly and with mixture is advanced certain distance to the in-vessel composting system discharge end, and the turning degree of depth is 1.2m, an endfeed in the in-vessel composting system; One brings out material; Work continuously, the in-vessel composting system slanted floor has the percolate relief outlet;
-slaking and temperature control: the mixture in the in-vessel composting system is through the mikrobe slaking, and 5-7 days curing times, wherein hot stage is 3-5 days, and temperature is 55 ℃-65 ℃, whenever is provided with the automatic temperature measurement device at a distance from 3m in the in-vessel composting system;
-ventilate: blower fan delivers air to the plenum pipe of in-vessel composting system bottom, air diffuser in mixture, for mikrobe provides oxygen, the oxygen level that the air-valve that is provided with through each plenum pipe is regulated mixture;
-becoming fertile processing: the mixture after becoming thoroughly decomposed is after screening, removal of impurities, and the content of allotment nutritive element carries out the packing of product and stores;
-foul smell is handled: deodoration system is made up of plexiglass tent, deodorizing airduct, deodorizing tower, deodorizing blower fan and chimney; The in-vessel composting system top is by the airtight covering of plexiglass tent; Under the suction function that the deodorizing blower fan produces; Introduce deodorizing tower through in-vessel composting system top deodorizing airduct and purify producing gas in the composting process, purify back gas from chimney to airborne release.
Worm conveyor is the shaftless worm conveyor.
Worm conveyor is the closed worm conveyor.
Because after adopting such scheme, the present invention has in use taked the extensive treatment process of intensification, is particularly suitable for the large-scale processing plant of urban construction.This method is converted into fertilizer with the organism such as waste of excrement slag, changing food waste, mud and farming and forestry output, has killed harmful pathogenic bacteria wherein, makes organic castoff compost become more valuable commodity.This method large-scale production, cost is low, and floor space is little relatively, can continuous production.Realize airtight and deodorizing in the production, avoid secondary pollution aborning.Adopt mechanized, reduce artificial the intervention as far as possible, not only ensure workers ' health, and alleviate working strength of workers.
