Description
(1) technical field
The present invention relates to waste water advanced treatment technology, belong to the environmental purification processing technology field, be specially wastewater treatment method in the wine making.
(2) background technology
Grape wine is a kind of product that utilizes Sucus Vitis viniferae behind the grape extraction juice to obtain through microbial fermentation, after storing and blending.Waste water in the wine making is from the whole process of producing, and processes such as pre-treatment, fermentation, aftertreatment, washing all produce a large amount of waste water.The principal pollutant of waste water are sugar, are the small molecule structure of several glucose molecules mostly, just can be by microbial technique to the glycan molecule disaggregating treatment in the waste water, and therefore adopting biotechnology is cost-effective method to this wastewater treatment.
Wastewater Treated by Activated Sludge Process grape wine waste water has advantage reliable, that treatment effect is good.But the sludge yield height is disposed trouble, under High Load Rate, active sludge is difficult for biofloculation takes place, and settling property is poor, and the water outlet concentration of suspension is than higher, be not suitable for the demanding sewage disposal of effluent quality is also needed a large amount of oxygenations, increased the capital construction working cost.Biological contact oxidation process is used very wide at home, and its major advantage is that processing power is big, and the anti impulsion load ability is strong, and floor space is few, and the mud growing amount is few, no sludge bulking, and operational management is convenient etc.But if Pollutant levels are higher or the pre-treatment effect is undesirable in the waste water, the organic loading of biological contact oxidation pond front end is higher, make the oxygen supply relative deficiency, the microbial film at this place is canescence, is in serious anoxic condition, and the terminal sophisticated aerobic biologic membrane in pond is the amber yellow.Simultaneously, the biological activity inhibitory substance concentration in the water is also higher, and microorganism is also had certain restraining effect.These factors make biological contact oxidation pond not give play to due effect, and treatment effect is undesirable.
And bio-disc system is the method that early is used for the grape wine wastewater treatment, have advantages such as treatment effect is more stable, working cost is low, power consumption is little, anti impulsion load, no sludge bulking, but early stage the initial cost height, be subjected to the temperature variable effect big, relatively poor at the regional treatment effect that temperature is on the low side.
(3) summary of the invention
The invention provides wastewater treatment method in a kind of wine making, its processing efficiency height, the little degree of treatment height of energy consumption, and, can accomplish the zero release of waste water to energy recycle.
Its technical scheme is such, it is characterized in that: it may further comprise the steps,
(1) acid adjustment
The grape wine waste water that will come out from pump well is regulated the pH value between 6.5～7.5 with sodium hydroxide;

Waste water in the equalizing tank is squeezed into the pre-acidification of pre-souring tank;
(4) anaerobic reaction
The waste water of pre-acidification is sent into anaerobic reactor, before reactor start-up, add the anaerobic grain sludge that contains low temperature resistant microbial strains, addition accounts for 1/5～1/2 of reactor useful volume, temperature of reaction is between 14 degrees centigrade～20 degrees centigrade, and the biogas that anaerobic reaction produces recycles as the energy after gas-water separation, desulfurization, dehydration;
(5) syllogic biological respinse
To send into three sections biological reaction tanks through the waste water of anaerobic reaction, each section comprises independent double oxygen and aerobic reaction member, independent waste water and bacterial classification return-flow system respectively, successively through three sections multistage double oxygen and aerobic reaction;
(6) precipitation process
To feed settling tank through the waste water of aerobic reaction precipitates;
(7) coagulating
Waste water through post precipitation is carried out coagulating, drop into solid polyaluminium chloride 1 gram～15 grams or liquid aluminium polychloride 3 grams～40 grams by waste water per ton
(8) sand filtration, sterilization and discharging
To dropping into quartz sand filler through in the waste water of coagulating, carry out sand filtration, adopt disinfection by chlorine dioxide then;
(9) sludge treatment
The mud that will come out from equalizing tank, anaerobic reactor, settling tank and coagulating sedimentation feeds the dosing pond, the consumption of the polymerize aluminum chloride in the dosing pond be mud 0.05%, the polyacrylamide consumption is 0.01% of mud, then with pressure filter dehydration, discharging at last.
It is further characterized in that: when the organic content of waste water in the pre-souring tank is higher, sending the part of contaminated water of anaerobic reactor discharge back to pre-souring tank relaxes, under the effect of recycle pump, send the waste water of pre-souring tank back to anaerobic reactor again and carry out anaerobic reaction then; Before coagulating, send the mud in the settling tank back in three sections aerobic reaction ponds and the pond the further aerobic reaction of waste water.
Adopt anaerobic in low temperature reaction bacterial classification and reactive system, multistage double oxygen aerobic reaction system to carry out wastewater treatment among the present invention, the operation stability height has the ability of very strong anti-shock loading, the processing efficiency height, it is 100mg/L that general COD goes out water quality standard, this technology water outlet COD only is 40mg/L, water reuse in can be directly, reach the zero release of waste water, sludge quantity is few, and is simple and practical, operational management and easy to operate, power consumption, medicine consume little, and running expense is low, and cost is general.And the methane gas that anaerobically fermenting produces burning is used for reactor heating, carries out the secondary energy utilization, and energy recycling has further reduced running expense.
