Embodiment 1

[0025] The embodiment of the present invention provides a microbial agent based on sewage treatment, including the following raw materials in parts by weight: 900 parts of composite bacterial liquid, 17 parts of trehalose, 16 parts of mannitol, 34 parts of soluble starch, 0.4 parts of vitamin D, vitamin 0.5 parts of E, 13 parts of xanthan gum, 0.12 parts of limonin, 3 parts of hexaflumuron, 4 parts of theophylline. Bacteria can absorb organic matter and hydrogen sulfide in sewage, and denitrifying phosphorus-accumulating bacteria can effectively denitrify and dephosphorize sewage in the sewage treatment system that operates alternately in anaerobic and anoxic environments. Oxygen adjustment, domestication of Rhodospirillum rubrum and green sulfur bacteria, and then the expansion of Rhodospirillum rubrum and green sulfur bacteria, so that Rhodospirillum rubrum and green sulfur bacteria can adapt to the alternate operation of anaerobic and anoxic In the sewage treatment system, ...

Embodiment 2

[0039] The embodiment of the present invention provides a microbial agent based on sewage treatment, including the following raw materials in parts by weight: 950 parts of composite bacterial liquid, 24 parts of trehalose, 22 parts of mannitol, 30 parts of soluble starch, 0.5 parts of vitamin D, vitamin 0.3 parts of E, 15 parts of xanthan gum, 0.15 parts of limonin, 5 parts of hexaflumuron, 2 parts of theophylline. Bacteria can absorb organic matter and hydrogen sulfide in sewage, and denitrifying phosphorus-accumulating bacteria can effectively denitrify and dephosphorize sewage in the sewage treatment system that operates alternately in anaerobic and anoxic environments. Oxygen adjustment, domestication of Rhodospirillum rubrum and green sulfur bacteria, and then the expansion of Rhodospirillum rubrum and green sulfur bacteria, so that Rhodospirillum rubrum and green sulfur bacteria can adapt to the alternate operation of anaerobic and anoxic In the sewage treatment system, ...

Abstract

The invention provides a microbial agent based on sewage treatment, and relates to the technical field of sewage treatment. The microbial agent based on sewage treatment comprises the following raw materials in parts by weight: 850-1000 parts of a compound bacterial liquid, 15-25 parts of trehalose, 15-25 parts of mannitol, 30-35 parts of soluble starch, 0.3-0.5 part of vitamin D, 0.3-0.5 part of vitamin E, 12-16 parts of xanthan gum, 0.1-0.15 part of limonin, 3-5 parts of hexaflumuron and 2-4 parts of theophylline. Oxygen of an anaerobic workstation is adjusted, rhodospirillum rubrum and green sulfur bacteria are domesticated, and then the rhodospirillum rubrum and the green sulfur bacteria are propagated, so that the rhodospirillum rubrum and the green sulfur bacteria can adapt to a sewage treatment system with alternate anaerobic and anoxic operation, the green sulfur bacteria play an antagonistic role on Beggiatoa, the growth of Beggiatoa is inhibited, excessive improvement of the water shear resistance of a microbial film is avoided, and the microbial agent is worthy of being widely popularized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a microbial agent based on sewage treatment. Background technique [0002] Untreated sewage usually contains excess organic matter, nitrogen-containing compounds and phosphorus-containing compounds. Sewage treatment methods include physical methods, chemical methods and biological methods. Biological methods are methods that use the metabolic functions of microorganisms to treat sewage. Compared with physical methods, biological methods have a higher degree of treatment, and biological methods have lower processing costs than chemical methods. [0003] Sulfides are commonly found in domestic sewage and industrial sewage. When denitrification and phosphorus removal are performed on sewage, if hydrogen sulfide exists in the sewage, it will easily lead to the excessive proliferation of sulfur bacteria in the sewage, thereby improving the adhesion of microbial membranes for ...
