Beneficial effect:
The present invention is based on the machining emulsifying waste water treatment process reasonable idea of MVR technology, technical process is simple, and MVR technology can by the COD of emulsified waste liquid from 1.3 × 10 in emulsifying liquid waste water process
4mg/L is disposable be down to 2000mg/L within, isolate the waste oil of oil length more than 90% simultaneously; The condensation of water of MVR mixes with the sewage of other lower concentration (COD concentration is generally at below 800mg/L) (sewage of low concentration: emulsifying liquid waste water generally needs to reach more than 5:1), and after through acidication, aerobic combination art breading, then realize qualified discharge (grade III Standard for COD index in GB8978-1996 " integrated wastewater discharge standard ");
The improvement of the present invention and original process ration:
1) pre-treatment (replacing ultrafiltration or coagulating sedimentation by MVR technology) makes biochemical system intake by original about 10000mg/L, within being down to 2000mg/L;
2) water ratio in concentrated solution is reduced within 10% further, can directly recycle;
3) eliminate twice pH adjustment and the operation such as Fenton oxidation, coagulating sedimentation, avoid producing a large amount of chemical sludges (being Hazardous wastes);
4) COD due to biochemistry water inlet is much lower compared with traditional method, simplifies anaerobic processing device (having changed UASB+ catalytic oxidation into acidifying+catalytic oxidation), saves biochemical occupation of land, reduces cost of investment.
From environmental angle, this technique employing MVR technology is that " zero release " of emulsifying liquid waste water provides possibility, the polymer substance " retained " in a large number becomes still liquid (waste oil of water ratio <10%) and can recycle, the concentrated solution (waste oil of water ratio >50%) that relative ultrafiltration produces, volume is reduced greatly; Relative to coagulating sedimentation, avoid producing a large amount of chemical sludges, all decrease the trouble of secondary treatment.
From technological angle, compare the two kinds of techniques mentioned in literary composition, stablizing of MVR process emulsifying liquid waste water is better, and the efficiency being separated oil content is high, significantly reduces the load of subsequent biological treatment, reduces the complicacy of biochemical treatment system.Be mainly reflected in: 1. ultrafiltration exists Membrane cleaning problem, very easily occurs film latch up phenomenon; And in the pretreatment technology of coagulating sedimentation, because dosage to change with water quality and is difficult to control, and chemical feeding quantity is larger; 2. the separation efficiency of MVR is far away higher than original technique, discharge enters pollutent mainly solubility volatile organic matter and the semi-volatile organic matter of follow-up water treatment device, the value overwhelming majority of COD is located between 1400 ~ 2000mg/L, the >10 in more original technique
4mg/L is the improvement of a matter, and follow-up biological treatment just can directly adopt acidifying+contact oxidation technology; Meanwhile, it also avoid the adjustment repeatedly of pH value and Fenton oxidation and the operation such as coagulation again; 3. the condensation of water temperature of MVR is generally at 40-60 DEG C, and after plant area's other domestic waters mixing, temperature is down to about 30 DEG C, and is conducive to microbial growth breeding, brings facility to biological treatment.
