Description
Technical field
The invention belongs to the field for the treatment of of water pollution of environmental project, more particularly to a kind of harmless processing of large-scale pig farm biogas slurry
And utilization of resources technique.
Background technology
With the continuous improvement of people's living standards, China's livestock and poultry breeding industry is grown rapidly.Livestock and poultry breeding industry has become me
One of the pillar industry of state's agricultural development, wherein pig, the sheep number of animals raised rank first in the world, large scale of pig farm have reached 40% with
On.But the fast development of large-scale cultivation industry, cause breeding waste (solid, liquid) to increase significantly, problem of environmental pollution
Also it becomes increasingly conspicuous.
Regulations modellings in China are looked into fowl feces of farm and are generally handled using celebrating oxygen hair alcohol technique at present.Anaerobic fermentation technology
It is widely used in terms of the bioenergy of sound feces of farm exploitation biogas, is realizing feces of farm recycling
Meanwhile effectively reducing the primary pollution of feces of farm.However, while handling waste progress anaerobic fermentation utilization,
Also a large amount of, concentrate, secondary pollutant-biogas residue and biogas slurry are produced.
Pass through aerobic hair ester along slag, organic fertilizer is made and returns soil, is utilized；But it is different from biogas residue.Biogas slurry
Processing becomes problem.First, biogas slurry is liquid, and mobility and easily blocking the common reed are standby, and difficulty is enclosed in transport；Two, biogas slurry intensive quantity is big, becomes
One evil, past, farm's ruleization degree are low, belong to peasant household's individual more and grow, oneself anaerobism hair, which is waken up, utilizes biogas, and biogas slurry is discharged into certainly
It in the soil of family, is applied directly in soil alternatively, resting waste, has not only been effectively utilized the buckwheat point of liquid, but also ring will not be polluted
Border.In recent years aquaculture large-scale degree be continuously improved and expand, it is adjoint and come largely control liquid, far from as before directly
It connects as fertilizer on-site elimination.Third can be caused containing some harmful heavy metals, antibiotic, hormone in biogas slurry without processing
Secondary pollution.4th, biogas slurry contains certain plant nutrient ingredient, and still, content is small.5th, to plant pest and beneficial at
Divide and deposit, brings biogas slurry treatment technique and technical complexity.Therefore, biogas slurry is innoxious, recycling treatment and comprehensive profit
With aquaculture industry of China is had become, the protrusion for controlling gas clean energy resource, agricultural environment pollution comprehensive treatment and agricultural sustainable development is asked
Topic.
Through retrieval, 103274571 B of patent CN disclose the utilization of resources and the processing method of a kind of livestock breeding wastewater,
Include the following steps：（1）Anaerobic digestion methane production；（2）Slagging-off；（3）Biological aerated filter is biochemical；（4）Disinfection；（5）Organic fertilizer
Manufacture.The present invention is based on anaerobic digestion methane production technology, BAF technologies, disinfection technologies to be combined, and is money with livestock breeding wastewater
Source handles it by anaerobic fermentation, produces biogas, produces the waste water after biogas again through being separated by solid-liquid separation, solid slag is used for conduct
The raw material of organic fertilizer is produced, organic fertilizer is produced, waste water is recycled using BAF technologies and after sterilizing and qualified discharge,
High treating effect, low energy consumption, and comprehensive utilization resource has economic benefit simultaneously.But supporting for meagre profit operation is in for China
For growing industry, build that the required investment of such treatment for cow manure facility is too big, operating cost is excessively high.
Therefore, seek that facility investment is few, operating cost is low and the efficient large-scale pig farm biogas slurry of processing, it has also become solve to support
Grow the key point of industry pollution.
Invention content
That the technical problem to be solved in the present invention is to provide a kind of facility investments is few, operating cost is low and being capable of efficient process rule
The harmless processing of large-scale pig farm biogas slurry of modelling pig farm biogas slurry and utilization of resources technique.
In order to solve the above technical problems, the technical scheme is that：A kind of harmless processing of large-scale pig farm biogas slurry and money
Source utilizes technique, innovative point to be：Include the following steps：

Biogas slurry meter, the hydrated calcium chloroaluminate that 0.5~1.5wt% is then added into special taper reaction kettle carries out adsorption treatment, and stirs
Mix 20~30min, natural subsidence after stirring is separated by solid-liquid separation, and obtains solid slag and treated biogas slurry；
（3）By step（2）Biogas slurry that treated is sent into aerobic system, with 100 parts by weight treated biogas slurry, then to aerobic system
The active microorganism microbial inoculum that 0.4~0.6wt% is added in system carries out 40~60min of biochemical treatment, then natural subsidence, solid-liquid point
From acquisition solid and liquid；
（4）To step（3）The liquid of acquisition is detected, if meeting livestock breeding wastewater discharge standard GB18596-2001, COD
≤ 150mg/l, BOD≤400mg/l, ammonia nitrogen≤80mg/l then recycle and carry out Fertilizer Transformed utilization.
Further, the step（3）In active microorganism microbial inoculum select growth promoting bacteria agent, bush mycorrhiza agent or biological prosthetic
One or more of microbial inoculum.
The advantage of the invention is that：The harmless processing of large-scale pig farm biogas slurry of the present invention and utilization of resources technique, processing equipment
Using taper reaction kettle and aerobic system, both equipment are commonly used equipment, can greatly reduce facility investment；Meanwhile with water
Change calcium chloroaluminate and the pollution factor in the biogas slurry of pig farm is removed by absorption as adsorbent；Natural pond after the adsorption treatment
Liquid, then biochemical treatment is carried out by aerobic system, treated, and liquid meets livestock breeding wastewater discharge standard, recyclable progress
Fertilizer Transformed utilizes, and solves the disposal difficulties of prior art pig farm biogas slurry, realizes the recycling treatment of large-scale pig farm biogas slurry and comprehensive
