Abstract
The invention discloses an activated sludge fertilizer. The activated sludge fertilizer comprises activated sludge, EDTA, iron sulfate, citric acid, potassium fulvate, sorbitol and ZnCl2. The activated sludge fertilizer effectively utilizes residual activated sludge in sewage treatment plants, the activated sludge is converted into an organic fertilizer after processing, and the activated sludge fertilizer has the advantages of good fertilizer efficiency, substitution of chemical fertilizers, increase of the yield of crops, use convenience, no secondary pollution and effective soil improvement.
Description
Technical field
The present invention relates to organic fertilizer technical field, particularly relate to a kind of active sludge fertilizer.
Background technology
The most of Wastewater Treated by Activated Sludge Process sewage that adopts of sewage work, after the processing power of active sludge declines, the utility value of residual active sludge just reduces, the major issue that the processing Ye Shi sewage work of residual active sludge faces, the organism and the microbial metabolism activity product that in excess sludge, mainly contain microorganism, Institute of Micro-biology's absorption, also contain a large amount of polysaccharide, protein, cellulosic material.What have is direct as farmland fertilizer after dehydration by active sludge.But the residual active sludge after wastewater treatment is directly as fertilizer, and weak effect, can not be effectively for crop provides nutrient.The high-efficiency organic fertilizer that how active sludge treatment is become can directly come into operation is to need now the problem of solution.
Summary of the invention
Object of the present invention is exactly to provide a kind of active sludge fertilizer for the defect of above-mentioned existence.This active sludge fertilizer has carried out effective utilization by sewage treatment plant residual active sludge, is converted into organic fertilizer after processing, and fertilizer efficiency is good, replaces fertilizer application, can improve crop yield, easy to use, can not produce secondary pollution, effectively improves soil property.
A kind of active sludge fertilizer technology scheme of the present invention is to comprise active sludge, EDTA, ferric sulfate, citric acid, potassium fulvate, Sorbitol Powder, ZnCl
2.
Comprise following composition by weight: 200 parts of active sludge, EDTA3-5 part, ferric sulfate 1-3 part, citric acid 3-5 part, potassium fulvate 2-3 part, Sorbitol Powder 2-4 part, ZnCl
21-3 part.
Ferric sulfate and EDTA are added in active sludge and stir 3-5 hour, then add successively citric acid, potassium fulvate, Sorbitol Powder, ZnCl
2after being uniformly mixed, after being dried, entering granulator granulation and obtain active sludge fertilizer.
Stirring velocity is 100-200r/min.
Drying means is 20-40 ℃ of cryodrying.
Drying means is that centrifugation is dry.
Beneficial effect of the present invention is: active sludge fertilizer cost of the present invention is low, and technique is simple, and noresidue, pollution-free, containing elements such as organic matter, nitrogen, phosphorus, potassium, also contain all kinds of trace elements and probiotics, not only as the good source of manure, and it is good soil improvement agent.In production and use procedure, can not utilize large amount of sewage to process remaining active sludge to environment simultaneously, both save a large amount of resources, protect again environment; Agriculture production is entered in benign cycle, obtain Sustainable development.
