Abstract
The invention discloses a kind of paper mill sludge compost, which belongs to field of fertilizer production；The production method is raw material with dry paper mill sludge 75%-77%, straw 15%-17%, cottonseed cake 6%, organic fertilizer fermentation agent 1%, fungicide 1%, produces paper mill sludge compost by the method for fermentation；Its advantage is that: provide a kind of method that compost is produced using hot fermentation as primary raw material using paper mill sludge, this method equipment investment is few, at low cost, paper mill sludge can be carried out to harmless treatment, turn waste into wealth, eliminate pollution, good in economic efficiency, not only certain economic benefit had been produced, but also has produced huge social benefit.
Description
Technical field:
The invention belongs to fertilizer field more particularly to a kind of compost produced using paper mill sludge as raw material.
Background technique:
Paper-making pulping enterprise will generate a large amount of sludge in production, these sludge become therefore how new pollution sources are handled
These sludge, are the problems that papermaking enterprise faces, and the simplest processing mode of these sludge is by dehydration equipment by sludge
Moisture content is reduced to after certain standard or naturally dry, is sent to garbage disposal site and is filled, and this method becomes processing waste
Method, time-consuming no income.It is found after being measured by the ingredient to paper mill sludge, paper mill sludge belongs to biosolids
Waste, it had not only contained the plant nutrients such as a large amount of cellulose family organic matter and nitrogen, phosphorus, potassium, but also contained micro heavy and disease
Paper mill sludge can be become agricultural fertilizer according to this characteristic by opportunistic pathogen, carry out resource utilization, due to be rich in sludge nitrogen, phosphorus,
The nutriments such as potassium are easy to the absorption of crops, during the fermentation, suitable additive are added in fertilizer, can be obtained
The comprehensive organic fertilizer of nutrient.Paper mill sludge can be carried out harmless treatment, eliminate and pollute by this method, using modern biotechnology,
The generation and discharge polluted in paper making process are reduced to greatest extent, improve resource, energy utilization rate, comprehensive utilization life
Waste during production, and equipment investment is few, good in economic efficiency, and paper mill sludge can be turned waste into wealth, and has both produced certain
Economic benefit, and produce huge social benefit.
Summary of the invention:
Present invention mainly solves the problem of be to provide it is a kind of using paper mill sludge as raw material batch produce compost method, produce this and make
The raw material that paper sludge composting uses has: dry paper mill sludge 75%-77%, straw 15%-17%, cottonseed cake 6%, organic fertilizer
Leavening 1%, fungicide 1%.
The present invention can be achieved through the following technical solutions:
A kind of production method of paper mill sludge compost, it is characterized in that being made of following steps:
(1) paper mill sludge, straw, cottonseed cake of the drying of formula ratio are sent into pulverizer, are sent into fermentation vat after crushing.
(2) fermentation vat is sent into the organic fertilizer fermentation agent of formula ratio, is sealed by fermentation after suitable water blending uniformly is added, the summer
Season fermentation 18-20 days, winter fermentation 25-30 days, fermentation temperature opened pond up to 45 DEG C -55 DEG C after fermentation, after fermentation
Material is sent into post-processing pond.
(3) fungicide of formula ratio is added in processing pond backward, after blending uniformly, discharging obtains after natural drying outdoor
To finished product paper mill sludge compost.
(4) in use, paper mill sludge compost can be applied in winter-spring season as base manure.
Preferably: the paper mill sludge is a heavy sludge.
Preferably: the straw is the mixture that corn stover and peanut straw press 8:2.
The beneficial effects of the present invention are: providing one kind using paper mill sludge is primary raw material using hot fermentation production compost
Method, this method equipment investment is few, at low cost, can by paper mill sludge carry out harmless treatment, turn waste into wealth, eliminate pollution,
It is good in economic efficiency, certain economic benefit was not only produced, but also produce huge social benefit.
