Abstract
The invention discloses a method for adjusting sludge composting aeration. The method comprises the specific steps as follows: after a sludge and wood chip mixed fermentation material is fermented for 5-7 days, smashed straw, furfural dreg, rice husk and plant ash are added and uniformly stirred, the temperature is increased to 60-65 DEG C at a constant speed, piling fermentation is performed for 8-10 days at the temperature, and turning for aeration is performed once every day, wherein the adding amount of the smashed straw, the furfural dreg, the rice husk and the plant ash accounts for 25%-30% of the mass of the mixed fermentation material. With adoption of the scheme, the sludge composting aeration can be adjusted, the fermentation time can be shortened greatly, and the cost can be reduced.
Description
Technical field
The present invention relates to fertilizer field, particularly relate to a kind of method of conditioning of mud compost air permeability.
Background technology
In recent years, along with the raising of people's environmental consciousness, sewage disposal obtains fast development in China, but brings another serious environmental issue thereupon, Here it is how properly dispose sewage disposal after the mud that produces, it has become whole sewage treatment industry problem demanding prompt solution.
The mud handled well will be a kind of well resource, but arbitrarily the secondary pollution that must cause environment is put at stand.Way mainly landfill, burning and the compost of this mud of current process, but the economic benefit of landfill and burning is negative benefit, is not too applicable to China's national situation.And namely compost adds other auxiliary materials in mud, for agriculture production after simple processing, this Measures compare economy, and meet the strategy of current the advocated Sustainable development of China.But because air permeability during sludge composting is poor, make its fermentation time long, cost of manufacture is higher.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of method of conditioning of mud compost air permeability, can the air permeability of conditioning of mud compost, greatly shortens fermentation time, reduces costs.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of method providing conditioning of mud compost air permeability, concrete steps are as follows: after mixed fermentation material fermentation 5-7 days of mud and wood chip, add disintegrated stalk, furfural dregs, rice husk and plant ash, stir, at the uniform velocity be warming up to 60-65 DEG C, bank up fermentation 8-10 days at this temperature again, and the quick-fried oxygen of turning every day once, the addition of described disintegrated stalk, furfural dregs, rice husk and plant ash is the 25%-30% of described mixed fermentation quality of material.
In a preferred embodiment of the present invention, the ratio of weight and number of described disintegrated stalk, furfural dregs, rice husk and plant ash is 2:1:1:8 ~ 10.
In a preferred embodiment of the present invention, the water content of described mud is 55%-60%.
In a preferred embodiment of the present invention, described heat-up rate is 0.8-1 DEG C/h.
In a preferred embodiment of the present invention, described stacking height is 75-85cm.
The invention has the beneficial effects as follows: by adding the disintegrated stalk of rational proportion, furfural dregs, rice husk and plant ash at the ferment middle of mud and wood chip, be conducive to regulating air permeability, greatly shorten fermentation time, reduce costs.
