Composite high-efficiency microorganism preparation for synergy of sewage treatment plant and synergistic process

Abstract

The invention discloses a composite high-efficiency microorganism preparation for synergy of a sewage treatment plant and a synergistic process. Active ingredients of the composite high-efficiency microorganism preparation comprise zoogloea, comamonas, bacillus, pseudomonas, alcaligenes and nocardia. A method for preparing the composite high-efficiency microorganism preparation comprises the following steps of: independently cultivating the zoogloea, the comamonas, the bacillus, the pseudomonas, the alcaligenes and the nocardia in culture media respectively to obtain a zoogloea culture, a comamonas culture, a bacillus culture, a pseudomonas culture, an alcaligenes culture and a nocardia culture; and mixing the cultures. When the composite high-efficiency microorganism preparation is applied to the synergy of the sewage treatment plant, the composite high-efficiency microorganism preparation is added into a biochemical tank of the sewage treatment plant after expanding culture and acclimatization, so the biomass and activity are improved, treatment capacity and treatment effect of a sewage treatment system are improved, and standard emission and stable operation of the system can be guaranteed.

Description

technical field [0001] The invention relates to a composite high-efficiency microbial preparation and a synergistic process for efficiency enhancement of sewage treatment plants. Background technique [0002] Biological sewage treatment technology has become the leading technology in the field of sewage treatment. As an economical, reasonable and effective sewage treatment technology, it plays an important role in improving the quality of water environment and preventing water pollution. [0003] The biological treatment of sewage is to use the metabolism of microorganisms to decompose and transform the pollutants in sewage to achieve the purpose of purifying water quality. [0004] The core of sewage biological treatment is to cultivate and domesticate the dominant microbial flora suitable for the characteristics of sewage, and maintain the microbial biomass and activity suitable for the concentration of sewage pollutants, so that the dominant microbial flora can be treated...

AI Technical Summary

Problems solved by technology

[0005] At present, sewage biological treatment generally adopts natural sludge to cultivate domesticated microorganisms. Although the technology is mature, it has insurmountable shortcomings, mainly reflected in: poor adaptability, toxic and harmful substances and high salt content in sewage will inhibit the growth of microorganisms and even cause Inactivation of microorganisms, it is difficult to treat most industrial sewage, especially high-concentration refractory organic sewage and high-ammonia nitrogen sewage; the cultivation cycle is long, microorganisms are easily inactivated during the maintenance of sewage plants, sludge bulking occurs, and sewage treatment plants must be restarted when the sewage treatment plant is in operation again. Cultivation; less biomass, poor degradation ability, low treatment efficiency, difficult to effectively and completely degrade macromolecules, refractory, toxic and harmful organic substances, nitrogen, phosphorus, etc., unstable effluent; poor treatment effect on ammonia nitrogen, and when ammonia nitrogen When the concentration is high, it will inhibit the activity of microorganisms, thereby reducing the treatment efficiency; the impact resistance is poor, the requirements for influent water volume, concentration, temperature, PH, etc. are high, and the operation and management are complicated; the operation is unstable, and it is difficult to ensure the normal operation of the sewage treatment plant. Stable operation and standard emission

Therefore, the use of natural sludge to cultivate and domesticate microorganisms has certain limitations, and the best treatment effect cannot be achieved. Especially with the discharge of a large amount of industrial sewage and the continuous improvement of national sewage discharge standards, it is difficult for the microorganisms cultivated and domesticated by natural sludge to meet the sewage biological requirements.
