Abstract
The invention relates to the technical field of sludge utilization, in particular to a method for producing an alkaline organic fertilizer by papermaking sludge, which comprises the following steps of: firstly, fully mixing the paper making biochemical sludge and alkaline substances for reaction to prepare a mixture; inputting 20 million compound microbial inoculums for per mg of the mixture; processing the mixture for 7 to 25 days at a temperature of between 15 and 60 DEG C; and finally, packing the mixture into packets, and applying after being placed for at least 15 days. The method not only has simple preparation, but also uses transportation time as microbial reaction time so as to save time and accelerate the production cycle. Particularly, the method uses the papermaking sludge so as to contribute to protecting environment and turning waste into treasure, greatly reduces the production cost, and has good economic and social benefits.
Description
Technical field:
The present invention relates to mud and utilize technical field, relate in particular to a kind of method of utilizing paper mill sludge to produce alkalescent fertilizer.
Background technology:
Along with the raising day by day of Chinese economic development and living standards of the people, the demand of paper increases swift and violent, papermaking enterprise take advantage of a situation one after another and on, actively expand the scale of production.Continuous expansion along with the papermaking enterprise scale, environmental protection and energy problem are also following, a large amount of waste water, waste residue, mud etc. need appropriate processing, energy prices continue to raise, become one of subject matter of the survival and development that influence enterprise, therefore take the method for the pragmatic principle of ' waste recycling ', ' making to measure ' with waste sludge from paper mill classification and processing and utilizing, become the task of top priority, the composition of paper mill biochemical sludge is mainly organic matter, silicon oxide, silicon oxide and part nitrogen phosphorus potassium.Traditional treating method is landfill and makes farming fertilizer, but can have a strong impact on water and soil environment and alkali-affected soil.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, and disclose a kind of not only environmental protection, and the fast method of utilizing the alkalescent fertilizer that paper mill sludge produces of cost running.
The objective of the invention is to be achieved by the following method:
A kind of method of utilizing paper mill sludge to produce alkalescent fertilizer; This method is earlier with papermaking biochemical sludge and the reaction of alkaline matter thorough mixing, is prepared into mixture, and every milligram of mixture drops into 2,000 ten thousand composite fungus agents, handles 7～25 days down for 15 ℃～60 ℃ in temperature, is packaged into bag at last and shelves after at least 15 days and use.
Wherein, the mixed weight per-cent of described paper mill sludge and alkaline matter is: papermaking biochemical sludge 10%～90%; Alkaline matter 10%～90%.
Wherein, described alkaline matter is a lime, mainly contains calcium oxide, magnesium oxide or calcium oxide and magnesian mixture.
Wherein, described alkaline matter is desuifurized, mainly contains calcium oxide, magnesium oxide or calcium oxide and magnesian mixture.
Wherein, described alkaline matter is a soda-manufacturing waste residue, mainly contains calcium oxide, magnesium oxide or calcium oxide and magnesian mixture.
Wherein, the pH value behind described papermaking biochemical sludge and the alkaline matter thorough mixing is controlled between 8～10.
Composite fungus agent is that yeast, milk-acid bacteria, photosynthetic bacterium, viride, actinomycetes mixed fermentation get.
The invention has the beneficial effects as follows, the present invention with paper mill sludge and the reaction of alkaline matter thorough mixing, shelved 10～20 days earlier, utilized in the alkalescent fertilizer and acid soil, useful microorganism is grown a health environment, replace acid soil harmful microorganism system; Moisture in the paper mill sludge is regulated and control to below 60% by original 78%; Throwing in composite fungus agent again handles; Being packaged into bag at last shelves after 15 days use at least.Wherein composite fungus agent mainly forms with multiple beneficial microorganism mixed fermentations such as yeast, milk-acid bacteria, photosynthetic bacterium, viride, actinomycetes, can produce effectively lytic enzyme such as a large amount of proteolytic enzyme, amylase, cellulase, chitinase in the fermenting process.Not only but ammonia nitrogen, sulfide, nitrate, the nitrite of decomposing and fermenting generation reduce the objectionable impurities of compost, can reduce the smell of compost simultaneously, thereby reach the harmless treatment purpose to fermented material; And the shortening fermentation time, and fermentation thoroughly, prevent Secondary Fermentation; The present invention just can directly encapsulate after processing, and in transportation engineering, microorganism plays a role in the mixture after the encapsulation, after as ready is passed to the point of destination, just in time is the finished product alkaline fertilizer of fertilising best period.The present invention preparation and alkaline fertilizer not only fertilizer efficiency height, preparation are simple, and utilize the time of transporting as the microbial reaction time, save time, shortened the production cycle, it is fast to have accelerated the cost running, especially utilize the soda-manufacturing waste residue not only to help environmental protection, turn waste into wealth, greatly reduce production cost especially.
