Background technology
Along with the significantly lifting of sewage treatment capacity, in treating processes, a large amount of excess sludge produced causes increasing concern.Relevant investigation display, often processes the wet mud (water ratio 85%) that ten thousand tons of sewage about produce 7 tons.The mud of these colloidal dewaters difficulty greatly again, and cost is very high.If without harmless treatment, throw aside arbitrarily, simple landfill, not only easily polluted air, soil and water source, serious threat HUMAN HEALTH and environmental safety, and also process cost after secondary pollution is higher, and thus country is classified as " hazardous substance ".According to measuring and calculating, China produce every year 3000 ten thousand tons ~ 4,000 ten thousand tons water ratio about 80% mud.Along with the arrival of " 13 ", sludge quantity also can increase.Expect the year two thousand twenty, the sludge yield of China will reach 6,000 ten thousand tons-9,000 ten thousand tons.Obviously, along with the fast development of sewage treatment industry, the process of mud is disposed and will be become unprecedented serious and urgent.
The process of Cities of Foreign Countries mud has developed the history about having 100 years with disposing, and the process of mud is all turn to final purpose with minimizing, stabilization, innoxious and resource.Municipal sludge contains abundant organism, but water ratio is higher, and containing harmful microorganism, parasite, heavy metal etc., if do not carried out modification, cannot directly apply.
Existing microbial organic fertilizer has the following disadvantages:
(1) living bacteria count amount is low, and miscellaneous bacteria rate is high;
(2) N-P-K content and organic content are all lower;
(3) water ratio of fertilizer is high, and granule strength is little, and granularity is uneven;
(4) existing microbial organic fertilizer, improves limitation to crop yield and nutrition content.
Summary of the invention
The present invention, for solving above technical problem, provides a kind of microbial organic fertilizer containing modification municipal sludge and preparation method thereof, to realize following goal of the invention:
(1) microbial organic fertilizer prepared of the present invention, living bacteria count amount is 8.3-9.6 hundred million/g, total nitrogen content is 7-10wt%, total phosphorous is 3-5wt%, and total potassium content is 8-11wt%, and organic content is 52.6-53.9wt%, water ratio 2.0-2.5wt%, granule strength is 10.8-11.5N, and granularity (2-3mm) is 97.6-98.4%, and miscellaneous bacteria rate is 2.1-2.6%;
(2) microbial organic fertilizer prepared of the present invention, for proportion of crop planting, improves crop yield, improves corps nutrient substances content.
For solving above technical problem, the present invention by the following technical solutions:
