Abstract
The invention discloses a method for preparing an activated sludge foliar fertilizer. The method comprises the following steps: mixing activated sludge and water, screening the mixture to obtain a suspension; adding hydrochloric acid and citric acid, mixing, stirring and performing centrifugal separation, adding a solid mixture into ammonia water, and performing centrifugal separation to obtain the liquor after stirring; adding sophocarpidine, ammonium molybdate, itaconic acid and diethyl aminoethyl hexanoate, and uniformly stirring to obtain an activated sludge spray-type fertilizer. According to the method, the residual sludge in a sewage treatment plant is fully utilized, the activated sludge foliar fertilizer is rich in nutrition and wide in functions, does not have a toxic or side effect, has good application prospects in aspects such as planting industry and environment protection and can replace chemical fertilizers in agricultural production to serve as a spray-type fertilizer in planting agriculture, and the quality and yield of the product are improved.
Description
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of preparation method of active sludge foliar nutrient.
Background technology
After in sewage work, the processing power of active sludge declines, the utility value of residual active sludge just reduces, and active sludge is directly used as after dehydration to farmland fertilizer, wherein also contains a lot of objectionable impuritiess, directly as fertilizer, and weak effect.In recent years, the amount of application of nitrogen and phosphorous fertilizer increases year by year, the relative minimizing of fertilizer, multiple nutrient deficiency phenomenon is day by day serious, become and affect the limiting factor that crop yield improves, due to the excessive use of chemical fertilizer and the plantation year after year of crop, soil starts big area and hardens, and the profitable strain in soil is fewer and feweri, the soil-borne disease such as continuous cropping, root knot nematode is day by day serious, and the fertilizer of therefore developing highly effective and safe has become the trend of development.
Summary of the invention
Object of the present invention is exactly that a kind of preparation method of active sludge foliar nutrient is provided for the defect of above-mentioned existence.The inventive method takes full advantage of sewage treatment plant residual mud, fertilizer is nutritious, function is extensive, have no side effect, at aspects such as plant husbandry and environmental protection, there is good application prospect, can in agriculture production, replace chemical fertilizer in Implant agricultural as spray-type fertilizer, improve quality and the productive rate of product.
Preparation method's technical scheme of a kind of active sludge foliar nutrient of the present invention is to comprise the following steps:
(1) active sludge is mixed to rear 20 mesh sieves of crossing with water and obtain suspension;
(2) will in the suspension after sieving, add hydrochloric acid and citric acid to mix, 150-200r/min stirs 5 hours, and centrifugation, abandons filtrate, stays solid mixture;
(3) step (2) is obtained to solid mixture and add ammoniacal liquor, after stirring, clear liquid is got in centrifugation;
(4) add matrine, ammonium molybdate, methene succsinic acid, the amine DA-6 active sludge spray-type fertilizer that stirs to obtain.
In step (1), active sludge is 1:100 with quality ratio.
Each composition is in mass ratio: 100 parts of active sludge, 10% hydrochloric acid 5-50 part, citric acid 3-8 part, ammoniacal liquor 5-50 part, matrine 3-5 part, ammonium molybdate 3-8 part, methene succsinic acid 1-4 part, amine DA-6 2-5 part.
Beneficial effect of the present invention is: the inventive method takes full advantage of sewage treatment plant residual mud, fertilizer is nutritious, function is extensive, have no side effect, at aspects such as plant husbandry and environmental protection, there is good application prospect, can in agriculture production, replace chemical fertilizer in Implant agricultural as spray-type fertilizer, improve quality and the productive rate of product.Fertilizer prepared by the inventive method has effectively been removed the toxic ingredient in active sludge, the nutritive substances such as the polysaccharide in mud, protein, trace element, several mineral materials are extracted, coordinate other compositions, balance that can regulating plant nutrient, strengthens the resistance against diseases of plant.
