Microorganism growth promoting agent used in sewage treatment

Abstract

The invention discloses a microorganism growth promoting agent used in sewage treatment. The microorganism growth promoting agent is composed of a agent A and a agent B at a mass ratio of (1-2) : 20.The agent A comprises, by mass, a compound enzyme preparation of 2% to 6%, compound amino acid of 10% to 15%, compound vitamin of 6% to 8%, adenine of 1% to 5%, lecithin of 2% to 6%, glycerin of 6% to 10%, cottonseed cake powder hydrolyzate of 20% to 28%, corn steep liquor of 10% to 18%, and the balance a phosphate buffered saline solution; the agent B composes, by mass, an organic acid of 15% to 22%, sodium succinate of 8% to 12%, methanol of 25% to 30%, iron porphyrin of 3% to 6%, potassium fulvic acid of 8% to 12%, pyridoxal phosphate of 3% to 6%, manganese chloride of 2% to 6%, copper sulfate of 2% to 5%, and the balance sterile water. The using amount of the microorganism growth promoting agent is low; the microorganism growth promoting agent is beneficial for rapid enrichment of beneficial microorganism, is capable of increasing sludge activity and concentration rapidly, and improving sewage treatment efficiency, increasing system impact resistance, accelerating sludge domestication rate, restoring damage active sludge rapidly, shortening system debug time, improving the tolerance of waste water biochemical treatment system on chemical substances, and improving the adaptability of microorganism on temperature and salinity.

Description

technical field [0001] The invention belongs to the technical field of waste water biochemical treatment, and in particular relates to a biological growth accelerator for sewage treatment. Background technique [0002] The main purpose of wastewater biochemical treatment is to remove organic matter, nitrogen and phosphorus elements and colloidal solids that cannot be naturally precipitated in wastewater. According to literature reports, about 60% of the organic matter in urban sewage can only be removed by biological methods, and the removal of nitrogen in wastewater generally only depends on biological methods. At present, there are 90 urban sewage treatment plants in the world. More than % of the application of biological treatment, and most industrial wastewater treatment plants are also based on biological methods. [0003] The biochemical treatment of wastewater is to treat the pollutants in wastewater through the metabolism of microorganisms, which can generally be di...

Problems solved by technology

However, when the water body is seriously polluted and there are many organic substances and toxic substances in the sediment, the beneficial microorganisms in the system are inhibited and cannot play the role of decomposing pollutants, and even the biomass decreases, resulting in an ecological imbalance of the water body; Due to water quality fluctuations, lack of oxygen and other factors, the sludge activity is reduced or it is subject to a huge impact, making it difficult to self-repair in a short time

[0004] As a result, biological growth-promoting technology emerged as the times require, with low investment, low energy consumption, convenient management, and safety and reliability. For complex and refractory water bodies and sewage treatment systems with serious ecological imbalance, its effect is limited, and the improvement and restoration time is long, and it has little impact on promoting the evolution of the ecological structure to a high level.
