Prepare a method for described additive, comprise the following steps: by weight, by described each component mixing, to obtain final product.
A method for lignin-sludge, comprises the following steps: by pending drying sludge to water ratio≤20%, and compost, then adds additive, mixing.
Compost can utilize the microorganism in mud to carry out oxygenolysis to the organism in mud, finally makes it be converted into the higher humic-like substance of stability, and kills most of pathogenic bacteria and parasite in mud, reach innoxious object.
Preferably, the time of described compost is 72 hours.
Mud is after compost treatment, add above-mentioned additive, the nutritive element in mud can be supplemented, simultaneously to the heavy metal stabilization/solidification in mud, objectionable constituent in strict control mud, city sewage sludge reclamation is utilized, turns waste into wealth, make artificial soil in the engineerings such as landscape planting and Mine ecology reparation.
Preferably, the interpolation weight of described additive is 1% ~ 20% of gained mud weight after pending drying sludge, specifically depending on mud Middle nutrition element and Leaching of Heavy Metals concentration.
Beneficial effect of the present invention is:
(1) additive of the present invention is made up of jointly Iron sulfuret, magnesium oxide, bicarbonate of ammonia, urea, calcium phosphate, Calucium Silicate powder, potassium sulfate and plant ash, interacts.Objectionable constituent in mud can be carried out stabilization or solidification by the component of these additives effectively, can also supplement the nutrition of mud, thus can process municipal sludge and river bottom mud well.
(2) by drying sludge dehydration, compost and interpolation additive three of the present invention road technique, organic matter abundant in mud and plant desired nutritional element can be made full use of, objectionable constituent in strict control mud, recycling sludge is utilized, turn waste into wealth, make artificial soil in the engineerings such as landscape planting and Mine ecology reparation.This technology has good environment, economic benefit and social benefit, is the particular embodiment of developing a circular economy and building a resource-conserving and environment-friendly society, and integrates have important test and reference to the utilization of resources of pollutent and environmental protection industry.
