Bio-growth accelerator for sewage treatment

Abstract

The invention discloses a bio-growth-promoting agent for sewage treatment, which is composed of agent A and agent B, used together according to the mass ratio (1-2): 20, and includes the following components in mass percentage, agent A: composite enzyme preparation 2%‑6%, compound amino acid 10%‑15%, multivitamin 6%‑8%, adenine 1%‑5%, lecithin 2%‑6%, glycerin 6%‑10%, cottonseed cake powder hydrolyzate 20%-28%, corn steep liquor 10%-18%, the balance is phosphate buffered saline solution; agent B: organic acid 15%-22%, sodium succinate 8%-12%, methanol 25%-30%, Iron porphyrin 3%-6%, potassium fulvate 8%-12%, pyridoxal phosphate 3%-6%, manganese chloride 2%-6%, copper sulfate 2%-5%, the balance is none bacteria water. The bio-growth-promoting agent of the present invention is used in a small amount, which is conducive to the rapid enrichment of beneficial microorganisms, and rapidly increases the activity and concentration of sludge, thereby improving the efficiency of sewage treatment, improving the impact resistance of the system, increasing the domestication rate of sludge, and being able to quickly repair Damaged activated sludge shortens the commissioning time of the system; improves the tolerance of the wastewater biochemical treatment system to chemical substances, and improves the adaptability of microorganisms to 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.
