Brief description of the drawings
Fig. 1 is the process chart of mandarin orange can production wastewater treatment technique.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below Close specific embodiment and the present invention is expanded on further.
With reference to Figure of description, the present invention will be further described：
According to the operating procedure of the present invention, the mandarin orange can production wastewater treatment technological process as described in accompanying drawing carries out mandarin orange Orange can produces the processing of waste water, and present treatment technique is 1000~1400mg/L, BOD mainly for COD concentration5Concentration is 600 ~800mg/L, SS concentration for 800~1000mg/L mandarin orange can production waste water, after testing and statistics, the water quality situation be adapted to The discharge of wastewater of most of mandarin orange can manufacturing enterprise, therefore with preferable application value, present treatment technical process is such as Under：
Citrus production waste water enters grid pond, is intercepted and is removed after bulky grain tangerine valve pericarp debris into neutralization by grid Pond, grid can use upper and lower two layers of grid, its at the middle and upper levels grid grid interval be 7mm, lower floor's grid grid interval be 3mm, so as to efficiently be intercepted, and in the present embodiment, considers that grid selects individual layer tooth harrow formula from operation ease Mechanical grille, grid interval is 5mm.Milk of lime is added into neutralization pond to adjust waste water to neutral and add flocculant and make waste water Produce flocculation reaction wherein milk of lime to process using conventional meanses by quick lime, milk of lime and flocculant pass through dispensing Device automatic feeding enters neutralization pond, and neutralization pond bottom sets agitator, and agitator is arm stirrer, and its rotating speed is set to 30~40r/m adjusts more accurate, flocculation reaction more fully so as to pH, and well mixed rear agitator stops stirring being beneficial to Waste water in precipitation, neutralization pond enters in preliminary sedimentation tank the wastewater supernatant fluid carried out in preliminary sedimentation, preliminary sedimentation tank by preliminary sedimentation Be directly entered regulating reservoir, under turbid liquid by after filter press press filtration enter regulating reservoir, filter press select van-type hydraulic pressure filter press, van-type Hydraulic pressure filter press is durable in use, repair and operate more convenient, and filter cake is low compared with cake moisture obtained by other dewaterers, real With effect more preferably, waste water enters after removing the lightweight suspension thing in waste water by dissolved air flotation device in regulating reservoir in the present embodiment In biochemistry pool, by the metabolism of microorganism in biochemistry pool by the organic matter degradation in waste water, biochemistry pool passes through micro-pore aeration Device carries out oxygen supply, and the air demand of micro-hole aerator is 1.5~3m3Multiple micro-hole aerators are set in/a h, biochemistry pool, it is multiple Micro-hole aerator is in matrix distribution, each micro-hole aerator maximum service area 0.7m in biochemistry pool2, biochemistry pool pond body depth Coefficient of oxygen utilization can reach 21~25% during less than 4m, so that with good oxygen supply effect, waste water is entered back into second pond, lead to The further flocculation sediment of flocculant is added in passing second pond, second pond is vertical-flow second pond, and its center water inlet, periphery is excessive Water, and supernatant row up to standard after testing is set at the top of second pond in cleaning shoe, cleaning shoe 4~6r/min of rotating speed, second pond Put.
The bulky grain tangerine valve pericarp debris for intercepting separation by grid pond grid is used to process fish meal, grid pond, neutralization Separated in pond, preliminary sedimentation tank, regulating reservoir, biochemistry pool and second pond base sludge and regulating reservoir by air-dissolving air-float system Lightweight suspension thing handled by outward transport after mud dewatering apptss dehydration and drying, wherein grid pond, neutralization pond, regulating reservoir, life Change pond and second pond bottom is connected by scum pipe with mud dewatering apptss, sludge is more in second pond can pass through slush pump Aid in sludge discharge.
