Abstract
The invention relates to a treatment process of high-concentration pig farm wastewater. The processing process comprises the following steps of introducing the high-concentration pig farm wastewater into a regulating tank containing anaerobic bacteria, and carrying out primary anaerobic treatment on the wastewater; sequentially introducing the wastewater treated in the regulating tank into a screen filter tank and an acidifying slag storage tank, wherein the screen filter tank is connected with the acidifying slag storage tank through a sewage draining hole, and a sludge drying tank is arranged beside the acidifying slag storage tank; introducing the wastewater treated in the acidifying slag storage tank into a first-stage anaerobic tank and a second-stage anaerobic tank through a homogenizing tank; introducing the wastewater treated in the second-stage anaerobic tank into an SPR (surface plasma resonance) tank, wherein the SPR tank comprises an aerobic zone and anoxic zones, the aerobic zone is arranged at the middle of the SPR tank, and the anoxic zones are distributed around the aerobic zone; directly draining the wastewater treated in the SPR tank into a constructed wetland. According to the treatment process, the problems that the industrial wastewater of the pig farm is effluvial and is high in concentration of organic matters and ammonia nitrogen are solved, and the treated wastewater can be directly drained to the constructed wetland.
Description
Technical field
The present invention relates to a kind of waste water treatment process, specifically, relate to a kind for the treatment of process of high density Wastewater from Pig Farm.
Background technology
Utilization to pig farm fecaluria, is mainly by fecaluria separating dry space from moist space at present, makes pig manure be converted into efficient agriculture fertilizer through certain processing; And rinse sewage for urine and place, because its utility value is not high, thereby the phenomenon running off is quite serious.According to statistics, the turnover rate of China livestock and poultry urine and place wash-down water reaches more than 50%.The intractability of such waste water is higher, still lacks at present successful experience processing and utilizing livestock and poultry urine and place wash-down water.The factory effluent on pig farm often has stench, organic concentration is high, ammonia nitrogen concentration is high feature, if not treated just directly discharge can cause serious environmental pollution, can cause social strong reaction.
Summary of the invention
The present invention is directed to the extraction process of wheatgerm oil, a kind for the treatment of process of high density Wastewater from Pig Farm is provided.
Technical scheme of the present invention is: the treatment process of high density Wastewater from Pig Farm, comprises the steps:
(1) high density Wastewater from Pig Farm is passed into the equalizing tank that includes anerobe, carry out the preliminary anaerobic treatment of waste water;
(2) waste water of equalizing tank being processed passes into screen filtration pond, and then passes into acidifying storage slag bath; Described screen filtration pond is connected with storage slag bath by sewage draining exit, the other sludge drying pond of establishing of described acidifying storage slag bath;
(3) acidifying storage slag bath waste water after treatment enters one-level anaerobic pond by homogeneous pond, then enters secondary anaerobic pond;
(4) secondary anaerobic pond waste water after treatment enters SPR pond, and described SPR pond comprises aerobic zone in the middle of being arranged on and the branch oxygen-starved area in aerobic zone surrounding;
(5) SPR pond waste water after treatment can directly enter artificial swamp.
Preferably, in described one-level anaerobic pond, the training method of anaerobic sludge adopts same footwork, cultivates, tames simultaneously and carry out.
Preferably, described incubation time is 1 month, and described culture temperature is 20～25 DEG C.
Preferably, in described secondary anaerobic pond, the inoculum size of anaerobic sludge is 25% of secondary anaerobic pond volume, directly introduces waste water from equalizing tank mud is cultivated to domestication; When described anaerobic sludge particle diameter reaches 3.0mm, domestication finishes.
Beneficial effect of the present invention:
(1) the present invention adopts secondary anaerobic and SBR combination process to administer the waste water on this pig farm, COD in draining after treatment
cr, NH
3-N, SS, BOD
5all reach the requirement of " livestock breeding wastewater emission standard " (GB18596-2001) Deng indices;
(2) factory effluent that the invention solves pig farm has stench, organic concentration is high, ammonia nitrogen concentration is high feature, makes the present invention's waste water after treatment can directly enter artificial swamp.
Embodiment
The present invention is described further below.
The treatment process of high density Wastewater from Pig Farm, comprises the steps:
(1) high density Wastewater from Pig Farm is passed into the equalizing tank that includes anerobe, carry out the preliminary anaerobic treatment of waste water;
