Detailed description of the invention
Fig. 1 is the method for the present invention flow diagram.
Specific embodiment
Embodiments of the present invention will be further described below with reference to the accompanying drawings.
As shown in Figure 1, a kind of animal wastes water dirt method for separating and processing, comprising the following steps:
Step 1: in such a way that water rushes excrement, animal wastes being poured in manure lagoon；
Step 2: catalyst is added into the manure lagoon of step 1 and carries out deodorization；
Step 3: according in step 1 in manure lagoon fecal sewage concentration levels, be divided into the processing of 3 kinds of situations, a, work as excrement
When concentration of wastewater is suitable for, step 4 is directly carried out；B, when fecal sewage concentration is lower, need to first pass through pre- sedimentation, then walked
Rapid 4；C, it when hair miscellany content is more in fecal sewage, needs first to carry out unhairing processing to sewage, then carry out step 4；
Step 4: in step 3 treated manure lagoon fecal sewage carry out solid-liquid separation treatment；
Step 5: fermentation process being carried out to the solid-state excrement slag obtained after step 4 processing, obtained product is fermenting-ripening
Organic fertilizer；
Step 6: the liquid sewage obtained after step 4 processing being imported into manure storage pond, and carries out catalyzing deodorizing；
Step 7: dosing disinfection, filtration, purification and flocculation treatment are carried out to the liquid sewage obtained after step 6 processing；
Step 8: fermentation process being carried out to the solid-state excrement slag obtained after step 7 processing, product is the organic of fermenting-ripening
Fertilizer；
Step 9: the water purification up to standard obtained after step 7 processing is discharged.
The pre- sedimentation of the step 3 carries out rapid subsidence by the way that sedimentation agent is added.
The sewage of the step 3 carries out unhairing processing by hair interceptor.
The solid-liquid separation treatment of the step 4 uses solid-liquid separating machine.
Coarse rack is provided at section feeding before the manure storage pond of the step 6；Due to generally can band in farm's fecal sewage
Enter certain biggish impurity of floating material or volume, remove large volume sundries using coarse rack, prevents blocking feed pump.
The manure storage bottom of pond portion of the step 6 designs for tilting, and feed pump is placed in the low side in manure storage pond；Improve sewage in pond
Mobility prevents dead angle.
Overflow pipe is provided at the feed pipe of the solid-liquid separating machine；Since the mobility height of fecal sewage directly affects
The separating effect of solid-liquid separating machine is typically designed the treating capacity that inlet amount need to be greater than seperator, increases to improve separative efficiency
The mobility of fecal sewage improves treatment effeciency, must design overflow pipe on feed pipe.
The step 7 is used and is carried out in high efficiency particulate air filter or Sludge Bed.
The flocculation treatment of the step 7 is carried out using flocculant is added.
The dosing disinfection of the step 7 is carried out using chlorine-containing disinfectant is added.
It is different according to the field condition of animal wastes solid-liquid separation treatment, and accordingly take different process flows.First is that
When appearance fecal sewage concentration, ingredient are suitable for, directly it is separated by solid-liquid separation, without any pretreatment；Second is that fecal sewage concentration
When lower, to improve separative efficiency, need to first pass through pre- sedimentation, then be separated by solid-liquid separation；Third is that hair miscellany contains in fecal sewage
When measuring more, to prevent blocking waste removal equipment, after needing first to carry out unhairing processing to sewage, then solid-liquid separation treatment is carried out.It must
When wanting, three kinds of methods are applied in combination, can reach best separating effect, improve the efficiency of subsequent solid-liquid separation treatment, protected
Production equipment is protected.
Sewage treatment scale can be reduced, the recycling of resource and the energy is also convenient for.Excrement is done in manure fermentation workshop to ferment
Processing, is finally fermented into organic fertilizer, urine and sewage are pipelined to sewage-treatment plant, and that isolates after processing consolidates
Shape object transports to the processing of manure fermentation workshop, discharge after liquid handling is up to standard.
The SS that can remove 30%--40% in sewage is pre-processed through being separated by solid-liquid separation, improves the processing of subsequent sewage treatment process
Efficiency, while playing the role of protecting equipment.After being separated by solid-liquid separation pretreatment, in sewage 40% or so CODCr can remove, mitigate
The load of subsequent sewage treatment reduces sludge yield, reduces volume, the occupied area of processing unit, reduces investment.
Specific embodiments of the present invention are described in detail above, but it is merely an example, the present invention is simultaneously unlimited
It is formed on above description specific embodiment.To those skilled in the art, the equivalent modifications and replace that any couple of present invention carries out
In generation, is also all among scope of the invention.Therefore, without departing from the spirit and scope of the invention made by equal transformation and repair
Change, all covers within the scope of the present invention.
