Abstract
The invention provides a technique for developing landscape special nutrient soil by using municipal sludge, which comprises the following steps of: (1) adding a conditioning agent and a compound biological bacterial agent into the municipal sludge; (2) overturning the municipal sludge by using a mechanical overturning device; (3) ventilating the municipal sludge periodically by adopting a ventilating device; and (4) performing aerobic fermentation in an aerobic fermentation tank. The method is characterized in that: the conditioning agent adding into the municipal sludge is crop straws; the municipal sludge and the crop straws are blended together according to a dry weight ratio of 6:4; and the compound bacterial agent preferentially selected by a test is added into the mixture. A stirring overturning machine is used in the fermentation process of the municipal sludge; the ventilating device is a ventilating pipeline erected at the bottom of the fermentation tank and is used for conveying air through an air blower so as to supply sufficient oxygen to the aerobic fermentation; and a timing device is a timing switching instrument and is set to ventilate for one hour every three hours and ventilate six times a day. The technique ensures harmless and resource utilization of the municipal sludge, prevents secondary pollution on the environment, stabilizes organic substances which are easy to rot and stink, and turns the harmful into the beneficial.
Description
Technical field
The present invention relates to innoxious, the resource treatment techniques of organic waste such as a kind of mud, particularly a kind of technology of utilizing municipal sludge development landscape special nutrient soil.
Background technology
Municipal sludge is meant handles the solid waste that sanitary sewage produced, about water ratio 80%, usually the floss that contains various microorganisms and organic and inorganic granulometric composition in the domestic sludge, contain a large amount of hazardous and noxious substances, as parasitic ovum, pathogenic micro-organism, bacterium, synthesis of organic substance and heavy metal ion etc.Simultaneously also contain the required nitrogen of growth and development of plants, phosphorus, potassium in the mud and keep various trace elements that plant normal growth grows and the organic matter of the structure of improving the soil.China's sludge treatment adopts the method for burning, mummification or sanitary landfill more at present, and these are not that processing costs is too high, exactly environment are polluted, and is not suitable for current international form development.In the last few years, some local governments and enterprise were the booth of processing mud construction than higher gears, the import overturning machine, and these all cause the energy consumption height, and are expensive many, make the municipal sludge of producing that ferments not have market thereby cost is high.Having has following shortcomings such as pollution, processing costs is too high, energy consumption is big to environment
Summary of the invention
According to above technical problem, the invention provides a kind of technical solution of utilizing municipal sludge development landscape special nutrient soil.The present invention adds amendment by municipal sludge and composite bacteria agent step (1), mechanical tilting device carry out overturning step (2), the employing ventilation plant carries out carrying out the aerobic fermentation step in timing airy step (3), the aerobic fermentation groove and forms, it is characterized in that the amendment that adds is the crop material of pulverizing in municipal sludge, the dry weight of municipal sludge and crop material is puddled according to 6: 4 ratio, adds through overtesting to optimize next composite fungus agent.The equipment that municipal sludge fermentation is used has: stir overturning machine (certificate of patent number: ZL 00 2 34458.0); Ventilation plant is for setting up ventilator trunk and pass through the gas blower delivering gas in the fermenter bottom, and for aerobic fermentation provides competent oxygen, air flow is set at per minute 0.2m
3/ m
3(material); Timing device is the time switch instrument, is set at per three hours and ventilates one hour, ventilates every day six times.
The present invention is the digested sludge (about water ratio 80%) that the municipal sewage plant is disposed of sewage and produces, interpolation is by testing the crop material that preferably comes out as the fermentation amendment, according to 6: 4 mixed of dry weight, make mixture, the mixture water ratio is controlled at 50%-60%; Add the aerobic fermentation complex micro organism fungicide in mixture, adding proportion accounts for the mass percent 0.3%-0.5% of mixture; By tilting device and timing ventilation plant municipal sludge is carried out aerobic fermentation in the aerobic fermentation groove, fermentation time is about 12 days; Subsequently the mixture that ferments is made the afforestation special nutrient soil by pulverizing, sub-sieve.We by with the crop material of municipal sludge and pulverizing according to certain mixed, add the aerobic fermentation agent of becoming thoroughly decomposed, under mechanical overturning and force ventilated condition, carry out aerobic fermentation, make complicated organic matter degradation in the mud, kill pathogenic bacteria and parasitic ovum etc., realize sludge stabilization and innoxious, make the afforestation special nutrient soil by pulverizing, sub-sieve again.Say so more specifically producing the organic waste that contain poisonous objectionable impurities in the sewage treatment process,, reach purpose innoxious, resource type treating, make the afforestation special nutrient soil by aerobic fermentation.We are applied in mud nutrition soil in the afforestation construction, and are not applied on the field-crop, and objectionable impurities can not enter food chain and have influence on HUMAN HEALTH; Mud nutrition soil is applied in the garden soil, can improve the soil, and increases the gas permeability of soil, provides nutrient for garden plant growth again simultaneously.Present technique is the treatment facility that adopt to be fit to our current national conditions, adopts advanced zymotechnique, handles municipal sludge at short notice, makes the afforestation special nutrient soil, for Tianjin and even national afforestation soil improvement provide good medium.
Embodiment:
