According to the invention, the biogas obtained through anaerobic fermentation is converted into a heat source of mixed aerobic composting, and the biogas residue and biogas slurry mixture is used for producing bio-organic compound fertilizers.

Description

A kind of feces of livestock and poultry and crop material comprehensive utilization of resources method
Technical field
The present invention sends out and belongs to agricultural wastes comprehensive utilization of resources and field of environment protection, relate in particular to a kind of feces of livestock and poultry and crop material anaerobically fermenting, biogas utilization, biogas residue and biogas liquid mixture directly with the stalk of pulverizing, the resource utilization method of part feces of livestock and poultry mixing aerobic compost.
Background technology
At present, along with the fast development of China's livestock and poultry breeding industry, feces of livestock and poultry quantity discharged every day increases severely, if directly do not apply the farmland through effectively handling, can bring severe contamination to environment, even endanger peripheral villager's health.
At this problem, all adopt diverse ways that feces of livestock and poultry is carried out comprehensive utilization of resources both at home and abroad and handle, the most frequently used method is that the wet method anaerobically fermenting is handled.But adopt the wet method anaerobically fermenting to handle feces of livestock and poultry, can discharge a large amount of natural pond liquid every day.Because natural pond liquid all returns the field certain difficulty is arranged, residue natural pond liquid can cause secondary pollution to environment, therefore, seeks feces of livestock and poultry treatment process more advanced, more science, is current problem demanding prompt solution
The present invention is raw material with feces of livestock and poultry and crop material, mix the aerobic compost thermal source through transforming into again by dry method anaerobically fermenting gained biogas, the biogas residue and biogas liquid mixture does not carry out solid-liquid separation, be directly used in the production biological organic complex fertilizer, this utilization of waste as resource pattern provides a kind of novel method for feces of livestock and poultry and crop material comprehensive utilization of resources.Compare with the wet method anaerobic fermentation processing method that the past is commonly used, this technology is produced beyond the biological organic complex fertilizer except producing biogas, and a large amount of natural ponds liquid that also can solve the generation of wet method anaerobically fermenting can't effectively utilize and discharge a difficult problem.Simultaneously stalk is used for the dry method anaerobically fermenting and mixes the aerobic compost part material, not only reduced the harm that burning straw brings to environment, also can obtain good economic benefit.
Summary of the invention
The objective of the invention is to: the ight soil that produces at livestock and poultry farms in scale carries out comprehensive effectively processing.Comprise that the dry method anaerobically fermenting produces biogas, and biogas is used through transforming into the thermal source that mixes aerobic compost, the biogas residue and biogas liquid mixture that produces in the dry method anaerobic fermentation process is mixed with stalk, the part ight soil of pulverizing, mix aerobic compost, produce biological organic complex fertilizer.The invention provides a kind of feces of livestock and poultry and crop material comprehensive utilization of resources novel method.
Technical solution of the present invention is: a kind of feces of livestock and poultry and crop material comprehensive utilization of resources method, and step is as follows:
(1) anaerobically fermenting: solid content is regulated in the stalk mixing of feces of livestock and poultry and pulverizing reached 15%-40%, add the anaerobically fermenting inoculum and carry out producing methane through anaerobic fermentation and obtain the biogas residue and biogas liquid mixture, 30 ℃-40 ℃ of leavening temperatures, fermentation period 20-30d;
(2) biogas utilization: will use as the boiler combustion gas behind step (1) the gained marsh gas purifying;
(3) biogas residue and biogas liquid utilization: step (1) gained biogas residue and biogas liquid mixture is not carried out solid-liquid separation, directly as mixing aerobic composting material;
(4) mix aerobic compost: step (1) gained biogas residue and biogas liquid mixture is mixed with stalk, the part ight soil of pulverizing, mixed mixture is regulated water ratio and is reached 50%-60%, after C/N regulates 20-50, carry out aerobic compost, the aerobic compost cycle is about 20-35d, will regularly ventilate or turning during mixing aerobic compost, all proportions is mass ratio.
With step (1) gained biogas dewater, desulfurization handles the back and uses as the boiler combustion gas, the high-temperature-hot-water that boiler produces or steam are as the thermal source that mixes aerobic compost, with regulation and control leavening temperature and time.
Advantage of the present invention:
(1) the invention provides cover feces of livestock and poultry and a crop material comprehensive utilization of resources novel method.
(2) the present invention mixes the aerobic compost thermal source through transforming into again by dry method anaerobic ferment process gained biogas, not only can regulate and control leavening temperature and time, can also save the part of fuel energy.
(3) dry method anaerobic ferment process gained biogas residue and biogas liquid mixture does not need to carry out solid-liquid separation, can fundamentally solve natural pond liquid exhaust emission environmental problem directly as mixing aerobic composting material.
(4) dry method anaerobic ferment process gained biogas residue and biogas liquid mixture has carried out the C/N adjusting with after stalk, the part ight soil of pulverizing mix, and makes that to mix aerobic composting conditions more reasonable.
(5) dry method anaerobic ferment process gained biogas residue and biogas liquid mixture mixes aerobic compost with after stalk, the part ight soil of pulverizing mix, and produces biological organic complex fertilizer, has improved added value of product, makes product have more the market competitiveness.
(6) dry method anaerobically fermenting and mixing aerobic compost as part material, not only can be regulated the solid content of the required material of dry method anaerobically fermenting to stalk, can also regulate the water ratio that mixes aerobic compost material.
(7) dry method anaerobically fermenting and mixing aerobic compost as part material, not only can be turned waste into wealth stalk, can also reduce burning straw to the harm that environment brings, and have good benefits in environment and economic benefit.
