Abstract
The invention provides a furfural wastewater aerobic treatment nutrient, which belongs to the field of biotechnology. The nutrient is prepared by taking urea, phosphatic fertilizer, magnesium chloride, zinc chloride, iron powder, vitamin B5 and vitamin B12 as raw materials; and according to different weight percentage of the raw materials, series of nutrient products in three stages are formed. When the nutrient is used, furfural wastewater is diluted and an initial-stage nutrient is put in to perform initial-stage culture on aerobic bacteria; the concentration of the furfural wastewater is increased and a middle-stage nutrient is added for middle-stage culture; and the furfural wastewater is added in order to gradually increase COD concentration to the index of furfural wastewater after anaerobic treatment, and then a later-stage nutrient is added to allow anaerobic bacteria to work normally. The nutrient of the invention has the advantages of accelerating the reproduction of furfural wastewater-treating aerobic bacteria and the decomposition of organic substances, preventing sludge bulking from occurring during aerobic treatment, increasing the survival ability of the aerobic bacteria, speeding up the engineering debugging of aerobic treatment and enabling aerobic biological treatment to achieve optimal effect.
Description
Technical field
The invention belongs to biological technical field, is the nutritive substance in a kind of furfural waste-water aerobic treatment.
Background technology
Furfural claims that again (molecular formula is C to furtural
5H
4O
2), be important heterocyclic organic cpds; With the furfural is the nearly kind more than 1600 of Chemicals that raw material directly or indirectly derives, and uses to relate to various fields such as medicine, agricultural chemicals, resin, daily use chemicals.1 ton of furfural product of every production will produce about 24 tons of waste water, so problem of environmental pollution is a great problem that China's furfural industry faces, should need in time to solve.
The characteristic of furfural waste-water and treatment process: stronger acidity is arranged, contain 1.2%～2.5% acetate at the bottom of the tower in the waste water, be turbid shape, khaki color, transmittance＜60% dewaters, outside the acetate, also contains furfural, other micro-organic acids, ketone of minute quantity etc.COD is about 15000～20000mg/L in the waste water, and BOD is about 5000mg/L, and SS is about 250mg/L, and temperature is about 100 ℃.This waste water is not processed, and directly discharging must make water quality suffer severe contamination, has destroyed the ecotope structure.General improvement method mainly contains: chemical method, biological process (upflowing aerobic reaction, filtering type aerobic reaction etc.), support treatment process (sbr reactor, contact oxidation) well, wherein aerobic treatment is another road treatment process after the anaerobic treatment, is to guarantee the effluent quality standard; It acts on and handles furfural waste-water is obligato treatment process; But in the engineering debug stage, aerobic debugging can be wasted plenty of time and fund, strengthens the construction costs of water treatment like this; As debug bad; Can make that then integrated artistic can't move, so aerobic debugging is very important to integrated engineering, yet nutritive substance is essential in aerobic debugging.
Summary of the invention
The technical problem that the present invention will solve provides a kind of furfural wastewater aerobic treatment nutrient, in order to accelerate aerobic treatment engineering debug speed and the treatment effect that improves aerobic bacteria.
Technical thought of the present invention provides a kind of science and the actual nutritive substance that combines; For the aerobic bacteria in the furfural waste-water aerobic treatment provides the best nutritional material of different times, different proportionings, make the sewage initial failure period shorten and the microbiological treatment effect reaches optimality criterion.
Furfural waste-water belongs to high-concentration waste water, and (COD is about 15000～20000mg/L); Engineering with using anaerobic biological treatment earlier, is used aerobic biological treatment mostly again, makes its water outlet reach emission standard; Though its organic content is a lot; But lack required other nutritive substances (N, P and trace element) of aerobic bacteria growth, this makes that aerobic bacteria is to need for some time to adapt in breeding and decomposition furfural, and this just makes that the engineering debug time is elongated; As being required to be the sufficient nutrient material is provided, will makes aerobic bacteria breeding and decomposition rate accelerate like this in its laundering period.It is fast that aerobe is handled the mikrobe increment, and organism has 50～60% to be used for the bacterium increment, so N, P are required high.
COD∶N∶P＝100∶5∶1
This nutrition is to cultivate the serial nutritious produce article composition that aerobic bacteria initial stage, mid-term stage and later stage use.
