Description

Sewage treatment microbial preparation, production system and production method

Technical Field

The invention relates to the field of microbial preparation production, in particular to a sewage treatment microbial preparation production system and a production method.

Background

The normal water body is odorless and smellless, and the polluted water body is often accompanied with strong odor. Since the 70 s, the water pollution is becoming more serious, the eutrophication degree is deepened, and the condition that the water is smelly is very common, which not only influences the sensory quality of the drinking water, but also seriously damages the environmental quality. The causes of water body pollution are various, the main sources of the water body pollution are industrial waste, domestic sewage, agricultural sewage and the like, and the pig raising sewage in the agricultural sewage belongs to sewage which is high in phosphorus, ammonia nitrogen and COD and is difficult to treat. The livestock husbandry in China is in a rapid development stage, and due to the fact that the African swine fever is difficult to control and the market demand is continuously increased, the development of the live pig breeding industry towards industrialization, large scale and quality is promoted. The sewage is a difficult problem to be treated in the pig breeding process, can increase the cleaning difficulty, can also cause pollution to the drinking water of the pigs, and then increases the probability of various epidemic diseases of the pigs. Modern ecological breed technique can select to change traditional pig house into the floor pig house of small opening, change traditional drinking bowl into and exempt from the excessive drinking bowl that leaks, breed whole journey and do not wash by water, no sewage produces, the production of control sewage from the source, avoid sewage treatment's the degree of difficulty, this is the key link of modern ecological breed technique also, ecological breed has thoroughly changed the mode that people pig was thoughtlessly located in the past, implement the specialty breed to the live pig, the propagation approach of virus or bacterium has been reduced, sustainable development to live pig breed scale has positive influence. A traditional pigsty is transformed into a fermentation bed pigsty, a mattress is filled with fermentation padding, and a padding layer is regularly sprayed with microbial strains for decomposing pig manure and urine. The pig breeding wastewater is a special wastewater, and compared with other wastewater, the pig breeding wastewater has a higher COD value, is rich in N, P and other nutrient substances, and has a large difficulty in treatment because solid residues in water are mainly organic substances. The sewage treatment process of pig farm mainly utilizes anaerobic biological treatment technology, and has the advantages of high efficiency in degrading organic pollutant in water, but difficult removal of ammonia nitrogen in waste water. Therefore, intensive research needs to be carried out on the treatment of the aquaculture wastewater, and the screening and compounding of the microbial agent needs to be carried out.

The denitrification generally comprises four processes of ammoniation, nitrification, denitrification and assimilation, firstly heterotrophic bacteria convert organic nitrogen into ammonia nitrogen, the ammonia nitrogen is oxidized into nitrite nitrogen by autotrophic nitrifying bacteria, the nitrite nitrogen is oxidized into nitrate nitrogen by the autotrophic nitrifying bacteria, and finally the heterotrophic denitrifying bacteria reduce the nitrite nitrogen and the nitrate nitrogen into gaseous nitrogen to be removed from the sewage. However, the waste water after the existing sewage treatment is also directly discharged, and the treated waste water still contains more odorous substances and a large amount of bacteria, so that the waste of water resources is caused, and certain pollution is caused to discharged rivers, fields and the like.

Chinese patent CN105907673A discloses a microbial preparation, which contains Pseudomonas stutzeri, Bacillus subtilis, Lactobacillus, Alcaligenes faecalis and Aspergillus niger. The invention also discloses a preparation method of the microbial preparation and a method for enhancing the biochemical effect of water treatment by using the microbial preparation. The bacillus subtilis, the lactobacillus, the alcaligenes faecalis and the aspergillus niger in the microbial preparation can form dominant flora in a sewage treatment system, so that the treatment effect of COD (chemical oxygen demand) in sewage is enhanced, and particularly, after the bacillus subtilis, the lactobacillus, the alcaligenes faecalis and the aspergillus niger are matched with aniline degrading bacteria and aerobic denitrifying bacteria, the bacillus subtilis, the lactobacillus, the alcaligenes faecalis and the aspergillus niger can quickly form advantages in a printing and dyeing sewage treatment system, so that the COD, the aniline, the chromaticity and the total nitrogen of printing and dyeing sewage are quickly and pertinently degraded, and the treatment effect of the printing and dyeing sewage is enhanced.
