Description

A kind of rubber production wastewater treatment method
Affiliated technical field
The invention belongs to a kind of wastewater treatment method, specifically, relate to a kind of treatment process of rubber production utilization of wastewater resource.
Background technology
Rubber production waste water has acid, the characteristics such as solid contents is high, nitrogen content height that are; Be acidity and be because used in the glue process due to the peptizer such as acetate or formic acid, sulfuric acid; The rubber production discharge of wastewater is corrupt and produce stench in the environment, has a strong impact on resident's life.In the prior art; Mostly rubber mill is to adopt anaerobism and facultative lagoon system, oxidation pond system, Sludge System, bio-disc system, ground release etc. to the processing of rubber production waste water; It is perfect that these methods are all not enough; Can not carry out recycling to the organism in the waste water, can not make waste water reach discharging standards; Another kind of treatment process is to utilize methanobacteria to make anaerobic waste water fermentation and generation biogas, and with the part of heat energy as dry rubber, but the waste liquid after the fermentation does not still reach discharging standards; Also having a kind of treatment process is directly through liquid state fermentation, Rubber Industrial Wastewater is processed liquid fertile, and the liquid fertile concentration that this method makes is too low, transportation inconvenience in the sales process, and transportation cost is high.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the object of the present invention is to provide a kind of rubber production wastewater treatment method, to Rubber Industrial Wastewater utilize fully, odorless is pollution-free, turning waste into wealth forms the useful raw materials into biological organic fertilizer.
Technical scheme of the present invention is: utilize solid substances absorption Rubber Industrial Wastewater; Said solid substances is biological organic materials, and this biology organic materials is the single raw material of plant residues such as sawdust, husk, stalk, pericarp pomace, processing of farm products tankage, also can be above mixture; Rubber Industrial Wastewater is added in the solid substances; Make the total water content of solid substances reach 65% ± 5, solid substances under the effect of organism of fermentation flora, 70~85 ℃ of fermentations; Can repeatedly inject Rubber Industrial Wastewater to the solids stockpile between this yeast phase, said organism of fermentation flora is the thermophilic fermentation microorganism species.
As preferred implementation of the present invention, during the fermentation, the 3rd~9 day of fermentation divided and added Rubber Industrial Wastewater again to the solids stockpile for several times, and each addition is solid substances 100~125% of the back weight ratio of giving money as a gift.
Beneficial effect: rich in proteins, natural resin, carbohydrate, ash (mineral element), ammonia, acetic acid etc. in the rubber production waste water, this mixing element are the high quality raw material of producing biological organic fertilizer, and the present invention makes full use of this characteristic; Concentrated and the conversion of waste water is carried out synchronously; Solid-state carrier per ton can absorb 4-6 ton waste water, processes the biological organic fertilizer more than 1 ton, is equivalent to concentrate waste water more than 10 times; And whole concentration process is not increase energy consumption, do not prolonging under the condition in compost fermentation cycle and realize; To Rubber Industrial Wastewater utilize fully, odorless is pollution-free, reaches the treatment of wastes with processes of wastes against one another, changing waste into valuable, compared with prior art; Both had environmental benefit, social benefit, had higher economic benefit again.
Below in conjunction with specific embodiment the present invention is done further detailed description:
Embodiment
Embodiment 1,
Pomaces (about 15 tons of the material of giving money as a gift) such as 80 tons of pineapple peel, pineapple core, Herba Passiflorae Caeruleae skin, passionflower seed and 20 tons of sawdusts (about 15 tons of the material of giving money as a gift), organism of fermentation flora nutrient chemical mix and are solid substances, make stockpile; Fermentation, turning when waiting to pile more than the temperature rise to 70 ℃, the heap temperature descends after the turning; When treating that the stockpile temperature rises to more than 70 ℃ once more, inject Rubber Industrial Wastewater to stockpile, the solid substances moisture content reaches 65% behind the injection waste water; Afterwards; Whenever injected Rubber Industrial Wastewater at a distance from 2 days, the IR of each Rubber Industrial Wastewater and the ratio of solid materials dry weight are 1: 1, and turning immediately gets into secondary fermentation after the 4th water filling; At last, make 35 tons of biological organic fertilizer finished products.
Redundant moisture in the high-heat fermentation process evaporative removal Rubber Industrial Wastewater; Simultaneously; Make the solid substance in the Rubber Industrial Wastewater under the effect of organism of fermentation flora, change into the necessary soil ulmin of growing process; Solid-state carrier per ton (butt) can absorb 4~5 tons of waste water, processes 1.05 tons of biological organic fertilizers.In the treating processes of rubber production waste water because leavening temperature is high; The entire operation process does not have foul smell to produce; The nitrogenous source that is rich in the Rubber Industrial Wastewater; The organic content that finally makes finished product is up to 60~62%, and 6,000 ten thousand/gram of number of viable is to improving soil physical and chemical property, increasing plant biomass and have better effect.
Embodiment 2,
30 tons on husk, 10 tons of rubber oil cakes, 10 tons in sawdust and organism of fermentation flora nutrient chemical mix and are solid substances, use Rubber Industrial Wastewater to transfer to as the moisture content of solid substances about 65%; Make the stockpile of high 80cm, turning when waiting to pile more than the temperature rise to 70 ℃, the heap temperature descends after the turning; When treating that the stockpile temperature rises to more than 70 ℃ once more, inject Rubber Industrial Wastewater, make that moisture content reaches 70% in the solid substances to stockpile; Afterwards, whenever injected Rubber Industrial Wastewater at a distance from 2 days, the ratio of each Rubber Industrial Wastewater IR and solid materials dry weight is 1: 1.25; Turning immediately gets into secondary fermentation after the 5th water filling, and is last, makes 51 tons of biological organic fertilizer finished products.Redundant moisture in the high-heat fermentation process evaporative removal Rubber Industrial Wastewater; Simultaneously; Make the solid substance in the Rubber Industrial Wastewater under the effect of organism of fermentation flora, change into the necessary soil ulmin of growing process; Solid-state carrier per ton (butt) can absorb 5~6 tons of waste water, processes 1.05 tons of biological organic fertilizers.In the treating processes of rubber production waste water because leavening temperature is high; Its deodorizing, sterilization effect are remarkable; The nitrogenous source that is rich in the Rubber Industrial Wastewater, the organic content that finally makes finished product be up to 65%, to improving soil physical and chemical property, increasing plant biomass and have better effect.
