The mechanism of action of biochemical treatment of industrial wastewater system is: the material that some in trade effluent was not easily degraded by microorganism in trade effluent originally, be decomposed into small organic molecule or the inorganics of easily degraded, thus the organic concentration in reduction waste water, remove or reduce waste water to the toxicity of environment and harm.Biochemical treatment is the main technique that industry is applied with municipal wastewater process.This method is lower than physical chemistry method cost, widely applicable, its shortcoming be exactly influent quality or the water yield fluctuation time, or contain the material compared with difficult degradation at trade effluent, as phenyl ring class, solvent based organism, oils, cellulose family etc., biosystem easily breaks down, the effect of impact process, for the process of trade effluent, water inlet poor stability, causes biochemical system fluctuation of service, and the decubation of biochemical system continues the impact being subject to various change, biochemical system is made to be in the large state of Long-term Fluctuation.For above problem, just need a kind of biological growth promoter to strengthen the resistibility of microorganism in biochemical system, alleviate variation water quality to the impact of biochemical system.
The existing product for biochemical treatment of wastewater extra-nutrition, mainly contains solid and liquid two kinds of forms.The nutritional formulation that solid form is mainly compound, as various nitrogenous fertilizer or phosphate fertilizer, although these materials can be preserved for a long time, directly can add when variation water quality and not need now to buy existing use, but this kind of biological growth promoter solvability is poor, nutritive ingredient is single, and the degree of absorption of microorganism is limited, and the nutritive ingredient of supplementing is also limited, liquid form mainly adds the carbon source nitrogenous source trace element and somatomedin that microorganism can directly utilize, diversification of varieties and nutrition relative abundance, because this type of growth-promoting agent is equivalent to microbiological culture media, can produce well and the microorganism that amount reproduction is useless in transit, consume considerable nutrition in growth-promoting agent, and useless microorganism joins in biochemical system can bring new impact to system, therefore, this type of biological growth promoter is not easily preserved, can only be now with the current, but the variation water quality of upstream water inlet is sewage disposal operation, and factory is uncontrollable, therefore biological growth promoter cannot be added timely when running into variation water quality, biological growth promoter can be caused to add increase and other unnecessary loss of consumption, therefore, need now a kind of biological growth promoter badly, not only containing abundant nutritive ingredient, and can preserve for a long time in warehouse, can use at any time when needed.
Summary of the invention:
In order to solve the problem, the invention provides a kind of biological growth promoter, be made up of the raw material of following mass percent: starch 40-45%, caseinhydrolysate 10-12%, yeast extract 8-10%, EDTA3.5-4.0%, NaCl4.0-4.5%, vitamin H 1.5-2.0%, surplus is distilled water;
It is as follows that described Raw material processing prepares biological growth promoter method:
(1) raw material prepares as follows: starch 40-45%, caseinhydrolysate 10-12%, yeast extract 8-10%, EDTA3.5-4.0%, NaCl4.0-4.5%, vitamin H 1.5-2.0%, and surplus is distilled water;
(2) distilled water is joined in reactor, add caseinhydrolysate, yeast extract, EDTA, NaCl, vitamin H subsequently, stir 15-20 minute;
(3) temperature of reaction kettle is warming up to 60-70 DEG C, starch is added in reactor after stirring 30-60min and temperature of reaction kettle is warming up to 121 DEG C, stir 20-30min;
(4) when question response still temperature is down to about 40-45 DEG C, biological growth promoter will be obtained;
(5) get the biological growth promoter of step (4) when using, conventionally use after adding the water dilution of growth-promoting agent quality 8 times of volumes;
Raw material described in the present invention is commercially available prod.
Beneficial effect:
1, biological growth promoter of the present invention not only rich in nutrition content, in water, solvability is good, owing to have employed new growth-promoting agent proportioning, this growth-promoting agent can preserve more than 180 days, undergo no deterioration and affect growth-promoting agent effect, can use at any time when needs use, and the present invention is concentrated biological growth promoter, can certain transportation cost be saved.
2, starch containing high level in raw material of the present invention, Starch Hydrolysis is maltose to the disaccharides stage, monose (glucose) is obtained after complete hydrolysis, in Raw material processing process, Starch Hydrolysis can be become the micromolecular sugar such as disaccharides, this type of micromolecular sugared solvability is better, can be utilized fast by microorganism, in this formula, starch concentration is higher, in biological growth promoter of the present invention, the micromolecular sugared concentration such as disaccharides is higher after hydrolyzing, not only in use provide a large amount of carbon sources to microorganism, and rot-resistant effect is played in the breeding of osmotic pressure anti-bacteria that the soluble sugar of high density also can increase in water before use, by extended shelf-life.
3, starch is added in raw material of the present invention, the amylolytic polysaccharide having short chain, and disaccharides and monose, the microbe species contained in active sludge is more, although monose is beneficial to most to provide energy, but in the process of disposing of sewage, the organism of a lot of macromole difficult degradation is had in sewage, if be only to provide glucose some can be allowed to compare be easy to utilize the bacterium amount reproduction of glucose to become dominant microflora, but these floras can not play a role when degraded larger molecular organics, if provide the polysaccharide of a part, biochemical system is not impacted at last, and be beneficial to macromolecular microorganism of can degrading occupy in active sludge part advantage, can to degrade in the process of disposing of sewage the macromolecular organism of some difficult degradations, the processing efficiency of biochemical system will inevitably be promoted like this.
4, caseinhydrolysate with crude milk albumen for raw material, through the product of hydrolysis, decolouring, desalination, spraying dry, containing 18 kinds of total free aminoacidss, amino acid is the basis of synthetic protein, be one of the most basic nutritive ingredient of microorganism, adding caseinhydrolysate can provide the amino acid that can utilize fast to accelerate the reproduction speed of microorganism to microorganism on the one hand;
