Abstract
The invention discloses a method of producing an organic fertilizer with rice straw papermaking sludge. The method includes the steps of: 1) controlling water content of the rice straw papermaking sludge to 30-40%; and 2) adding humic bacteria, cow dung and a deodorant to the sludge in the step 1), and performing aerobic biologic fermentation, wherein C/N ratio of the fermentation material is 25-35:1, relative moisture is 45-60% and temperature is 55-65 DEG C, and fermentation time is 24-25 h. The method is short in fermentation time, allows continuous production and is convenient to carry out, has no stinky odor during fermentation, is low in energy consumption, turns waste into resources and achieves full utilization of papermaking waste. The organic fertilizer has no pollution and residual toxin on rice, and satisfies demands on green food and organic food.
Description
Technical field
The present invention relates to a kind of method utilizing rice straw paper mill sludge to produce fertilizer.
Background technology
According to State Statistics Bureau's relevant statistics, within 2014, national Oryza glutinosa sown area is 30,310,000 hectares, Oryza glutinosa total output is 1.72 hundred million tons, understand according to the estimation algorithm (1 kilogram of Oryza glutinosa about produces 1.1 kilograms of straws) of crop yield with straw, China there are about the Oryza glutinosa straw of 1.89 hundred million tons every year, and annual reserves are the abundantest.
The main way of the process of Oryza glutinosa straw has at present: chopping and returning, on-site incineration, biomass power generation, papermaking etc..Chopping and returning affects the sowing in the coming year, has increased the weight of pest and disease damage；Biomass power generation is owing to being affected by haul distance, and beyond the increase at double of transportation radius cost of transportation, generating is not made money；On-site incineration serious environment pollution, is prohibited by country.Using Oryza glutinosa straw as the fibrous raw material of papermaking, it is possible not only to realize the recycling of waste resource, but also the paper industry dependence to timber can be reduced, improve environment.
For avoiding the pollution to environment of Oryza glutinosa straw papermaking (slurrying) waste water, process it is generally required to waste water to be first passed through biological or chemical etc., discharge again after water quality is qualified, can produce substantial amounts of paper mill sludge in this water treatment procedure, the paper mill sludge the most effectively utilizing waste water treatment section to produce is the problem that the sector needs to solve.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of method utilizing rice straw paper mill sludge to produce fertilizer.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The method utilizing rice straw paper mill sludge to produce fertilizer, comprises the steps:
(1) by the water content control of rice straw paper mill sludge 30～40%；
(2) adding humic bacterium, cattle manure and deodorizer to the mud of step (1) and carry out heat aerobic organisms fermentation, wherein, the C/N of fermentation materials is 25～35:1, relative humidity is 45%～60%, temperature is 55 DEG C～65 DEG C, and fermentation time is 24～25 hours.
Further, described humic bacterium is root nodule bacteria and/or fulvic acid.
Further, mud per ton adds the humic bacterium of 100-150 kilogram.
Further, mud per ton adds the cattle manure of 100-150 kilogram.
Further, mud per ton adds the deodorizer of 10-15 kilogram.
For ease of depositing and transporting, the material that step (2) ferments is carried out pelletize, is dried.
Beneficial effects of the present invention
1, fermentation time is short can produce continuously, easy to operate.
2, sweat odorless, energy consumption is low.
3, turn waste into wealth, it is achieved making full use of of papermaking waste.
4, fertilizer nuisanceless to Oryza glutinosa, without residual hazard, meet pollution-free food and Organic food fertilizer nutrient.
