Abstract
The present invention relates to a kind of processing method of livestock breeding wastewater, the method includes at least pretreatment stage, biochemical treatment stage and advanced treating stage, and the pretreatment stage is included at least to waste water progress grid tentatively cleans, slanted screen separates and coagulating sedimentation；The biochemical treatment stage includes at least waste water and carries out anaerobic fermentation, anaerobic precipitation and AB method biological carbon and phosphorous removal；The advanced treating stage, which includes at least, carries out photochemical catalytic oxidation, biological denitrificaion to waste water, agricultural fertilizer is made by the technical program treated waste liquid, good manure resources are provided for agricultural, the extraction and recycling of biogas are realized in wastewater treatment process simultaneously, waste water is after processing, better than breeding wastewater discharge standard, the qualified discharge or Treated sewage reusing of breeding wastewater are realized, it is energy-saving and environment-friendly.
Description
Technical field
The present invention relates to field of waste water treatment more particularly to a kind of processing methods of livestock breeding wastewater.
Background technique
Aquaculture is the important industry of China's rural development.In recent years, with the continuous expansion of cultivation scale, raising number
Amount sharply increases so that a large amount of swine manure wastewater becomes pollution sources, the pollution that these farms generate such as cannot get and
When handle, will do great harm to the environment, cause the deterioration of the ecological environment, animal products quality decline and to jeopardize human body strong
Health, the lag of aquaculture pollutant abatement technology will seriously restrict the sustainable development of aquaculture.
Currently, mainly having comprehensive utilization and processing qualified discharge two to the processing method of scale livestock and poultry farm liquid dung both at home and abroad
Major class.Comprehensive utilization is that biomass energy utilizes at many levels, builds the ecological agriculture and guarantee the good approach of agricultural sustainable development.But
It is, at present since livestock and poultry farm raising administration way in China's falls behind, in addition comprehensively utilizing the not in place of preceding Anaerobic Treatment, often to make livestock and poultry
Liquid dung led to the problem of during comprehensive utilization it is very much, as waste water yield is big, complicated component, pollutant concentration is still after processing
Dilution water very high, used mostly and by season pouring is influenced.
For handling qualified discharge, no doubt domestic and international process flow used is roughly the same, i.e. separation of solid and liquid-anaerobism
Digestion-Aerobic Process for Treatment still for China is in the cultivation industry of meagre profit operation, builds such treatment for cow manure facility institute
The investment needed is too big, operating cost is excessively high.Effective improvement of Stock raising waste has become puzzlement world environments worker's
One of Three Difficult Issues.For its discharge amount, organic matter is industry and urban life waste by the discharge amount of equivalent of COD
2 times of discharge amount.More bad, industry and urban life waste are effectively administered, and China's cultivation is discarded
The improvement of object also rest on do not handle or simply dealt situation under.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of processing method of livestock breeding wastewater, institutes
Method is stated including at least pretreatment stage, biochemical treatment stage and advanced treating stage, the pretreatment stage includes at least pair
Waste water progress grid tentatively cleans, slanted screen separates and coagulating sedimentation；The biochemical treatment stage includes at least waste water and carries out anaerobism
Fermentation, anaerobic precipitation and AB method biological carbon and phosphorous removal；The advanced treating stage include at least to waste water carry out photochemical catalytic oxidation,
Biological denitrificaion；Wherein, it is equipped with conditioning tank between the pretreatment stage and biochemical treatment stage, is equipped with water inlet in the conditioning tank and adjusts
Save monitoring portion, water inlet adjusting monitoring portion include: for monitor the hygrosensor of waste water temperature, for monitor waste water chlorine from
The chloride ion detector of sub- concentration, the heavy metal ion detector for monitoring concentration of heavy metal ion, for monitor colloid and
The fine particle detector of small suspension content, the thermostat for adjusting waste water temperature are flowed into for controlling waste water
First drain valve of UASB unit flows into the second drain valve of wedge-shaped sieve separation unit for controlling waste water, for controlling waste water
Flow into the third drain valve of coagulating sedimentation, the distributed A/D acquisition module for receiving monitoring data, for the list of data processing
The distributed digital input/output module of piece machine, the PC terminal for controlling the single-chip microcontroller and feedback control information；It is described
Water inlet adjusts monitoring portion and is visited the hygrosensor, chloride ion detector, heavy metal ion by distribution A/D acquisition module
It surveys the information that device and fine particle detector detect and is transmitted to the single-chip microcontroller, inputted by the single-chip microcontroller based on PC terminal
The water inlet of UASB unit require to carry out data processing to the monitoring information, and processing result inputted through distributed digital defeated
Module feeds back to the thermostat, the first drain valve, the second drain valve and third drain valve out.
According to a preferred embodiment, the treatment process of the pretreatment stage is that livestock breeding wastewater is passed through machine
Tool grid carries out primary slagging-off, and carries out secondary slagging-off through the wedge-shaped sieve separation unit of manure pit inflow, by what is removed the gred into secondary excessively
Waste water inputs coagulating sedimentation unit and carries out coagulating sedimentation, and the waste water for completing coagulating sedimentation is inputted conditioning tank.
According to a preferred embodiment, the treatment process in the biochemical treatment stage is useless to carry out conditioning tank conveying
Water inputs UASB unit first and carries out anaerobic fermentation, and the waste water input anaerobic precipitation pond that fermentation is completed carries out anaerobic precipitation, and
AB method biological carbon and phosphorous removal unit is sent into the waste water that anaerobic precipitation terminates and carries out denitrogenation dephosphorizing, to complete the biochemistry to waste water
Processing.
According to a preferred embodiment, flocculation sedimentation tank is sent into the waste water by biological treatment stage and is precipitated
And photochemical catalytic oxidation unit is sent into through intermediate pool and starts Sewage advanced treatment.
According to a preferred embodiment, which is characterized in that the treatment process in the advanced treating stage includes to defeated
The waste water for entering photochemical catalytic oxidation unit carries out catalysis oxidation, and completes to take off by anoxic MBBR, aerobic MBBR unit and whole shallow lake pond
Nitrogen processing, it is final to realize wastewater to reach standard and discharge.
According to a preferred embodiment, the UASB unit water inlet index are as follows: 5-40 DEG C of inflow temperature；Contents of residual chlorine
No more than 0.05mg/L；Heavy metal ion content is not more than 0.1mg/L；Sewage quality index S DI is not more than 3.0.
