Description
Technical field
The present invention relates to a kind of organic composite fertilizer of producing with domestic sludge; Specifically it is with sewage work's sludge discharged in handling the sewage process; Through mechanical dehydration; Powder after drying, abrasive dust, sorting and pig, dove and rabbit excrement are the organic composite fertilizer of main material production again, belong to the waste treatment field.
The invention still further relates to the method for manufacture of this organic composite fertilizer.
Background technology
Domestic sludge is the floating foam residue of mixing that sewage that the municipal sewage plant adopts chemical process that the resident is discharged the in daily life sedimentable matter that carries out producing in the treating processes and sewage surface drift out.Mud is the solid part in the sewage, on the composition is being the very high a kind of semi-solid waste of a kind of boundary water ratio between inorganics and organism.A B-grade sewage treatment plant, the sludge quantity of generation accounts for 0.5%～1% of the total amount of disposing of sewage, and along with the fast development of China's economic society, urban population sustainable growth and urbanization rate progressively improve, and the demand of city central water supply amount increases year by year.The quantity discharged of sewage is increasing, and the generation of mud also increases sharply.The mud of a large amount of accumulation not only will take a large amount of soils, and objectionable constituent wherein such as heavy metal, pathogenic bacteria, parasitic ovum, organic pollutant and foul smell will become and influence one of urban environmental hygiene and endanger greatly.Effective treatment technology is all actively being sought by governments at all levels and relevant department, and China mainly is to adopt burying method to handle, to reduce the pollution to environment to the treatment process of domestic sludge at present.But, the composition more complicated of domestic sludge, water ratio is high, and intractability is big, heavy metal particularly, if unprocessed direct landfill, will contaminated soil and groundwater resource, be easy to generate new secondary pollution, environment is caused serious harm.Long-term landfill need take a large amount of land resources; How properly scientifically domestic sludge to be carried out treatment and disposal; Make it reach minimizing, stabilization, innoxious and resource utilization, become a big research topic of scientific and technical personnel's extensive concern of China and even whole world environment circle.
Summary of the invention
The object of the invention provides a kind of organic composite fertilizer that uses domestic sludge, pig stable dung, pigeon dung and rabbit excrement as main material production for the problem that solves above-mentioned existence just; Thereby solved the pollution that domestic sludge, pig manure, pigeon dung and rabbit excrement produce environment; Solved the resource regeneration of domestic sludge, pig manure, pigeon dung and rabbit excrement again; Turn waste into wealth, change evil and be benefit, realized that the resource benign cycle of waste utilizes.
The present invention also provides the method for manufacture of this organic composite fertilizer.
The objective of the invention is to realize by following technical proposal;
A kind of organic composite fertilizer of producing with domestic sludge, it is processed by the following weight proportion raw material:
The floating foam residue that described domestic sludge powder throw out that to be sewage work carry out producing in the treating processes to sewage and sewage surface drift out; After process mechanical dehydration, deodorizing, disinfection digestion process become ripe sludge, after drying, abrasive dust, sorting, process particle diameter again and be powder less than 0.18mm;
