What is the role of sewage treatment bacteria in river treatment? 150

Gandu sewage treatment bacteria include: river treatment bacteria, photosynthetic bacteria, Bacillus subtilis, compound bacteria, nitrifying bacteria, denitrifying bacteria and so on.

Function; 1. Eliminate the phenomenon of black odor

To eliminate the phenomenon of black odor and restore the basic ecological environment of the water body, this stage is mainly to use Bacillus subtilis, photosynthetic strains and composite strains to establish dominant microorganisms.

2. Reduce the organic pollution of ammonia nitrogen

Mainly through nitrifying bacteria, the nitrate nitrogen and ammonia nitrogen in the water body are converted into nitrogen and emitted into the air, so as to achieve the purpose of reducing ammonia nitrogen.

3. Reduce the COD index

By adding compound bacteria, the COD of the water body is reduced, and a virtuous cycle ecosystem is formed.

Decompose the sediment and organic matter of the water body to reduce the pollutants of the water body.

4. Digestion of sediment and improvement of water body;

Photosynthetic bacteria are a general term for a class of microorganisms that use light as energy source, carbon dioxide or small molecule organic matter as carbon source, hydrogen sulfide and other hydrogen donors, and carry out complete autotrophic or photoheterotrophic growth but do not produce oxygen. In nature, photosynthetic bacteria are extremely widely distributed and have strong vitality.

5. Quickly reduce COD and ammonia nitrogen in the water body of the black and odorous river, eliminate hydrogen sulfide in the sediment, inhibit the generation of harmful bacteria and cyanobacteria, improve the transparency of the water body, and play the role of water purification.

7. Precautions:

Bacillus subtilis is an aerobic bacterium, so the dissolved oxygen in the required system is more than 2 mg l;

Bacillus subtilis has a strong competitive advantage in soil and sewage, avoiding overuse;

In this regard, the main thing is to use some agents, so that a very good effect can be achieved, and the disinfection and sterilization of these agents is relatively good.

Mainly it can play a role in cleaning up the river, because its purity can avoid the reproduction of organisms very effectively.

The strains play a role in purifying water quality, speeding up water purification, and preventing secondary pollution in river treatment. The main thing is to use biological treatment water quality to better protect the environment and water resources.

These bacteria are able to break down large and harmful substances.

Hello, their role in the river is actually equivalent to a decomposer. In fact, it is all kinds of bacteria that will decompose some of the substances in it.

The role of the military branch in walnut control and river management refers to the one that cleans it up and disposes of it so that it can be exposed to the water.

Sewage treatment bacteria are equivalent to a treated water in the contract.

Happily, the role of the bacteria in the river is to affect the production system of the society and the survival and development of fish.

This is equivalent to a biochemical, dosing treatment bacteria, cultivating this bacteria to nitrate the organic characteristics inside, generally used in, organic nitrogen, organic phosphorus, COD, etc.

Hello, sewage treatment bacteria have the effect of eliminating miscellaneous bacteria and removing peculiar smells in river treatment, and are conducive to the ecological environment.

Water treatment bacteria play a decisive role in wastewater treatment.

Water regeneration can be better realized, which is a good way to deal with pollution.

Its function is to degrade some slightly polluting substances.

The link of sewage treatment in the river treatment and environmental protection is also to make the environment better, environmental awareness and energy saving and drainage.

On the first day of May, the role of the military and government in river management is to make garbage more efficient to dissolve.

1. Decompose and consume all kinds of dirt in the river through strains.

2. Remove odors.

3. Reduce the water quality indicators such as ammonia nitrogen, nitrite and hydrogen sulfide in the river through the chemical reaction of the strain.

The bacteria are in the river, and the role here is to adsorb toxins.

What is the role of sewage treatment bacteria in river treatment? For the free, you should go to the EPA and ask them, and they will tell you what it does. You can also go to the search for help, there should also be a correct way to deal with it on the Internet, and if you want the correct answer, you will know it as soon as you ask.

What is the role of sewage treatment bacteria in river treatment? There are many kinds of this.

The role in river management is different, and the specific situation should be further excluded.

When it comes to sewage treatment equipment, we have to say that the sewage treatment bacteria that can effectively degrade the pollutants in the sewage, what are the common bacteria in sewage treatment?

First of all, let's understand its concept, a large number of various types of sewage strains through artificial screening of high-quality strains, and then through a series of domestication, cultivation and obtain salt-resistant, impact-resistant, stable sewage treatment strains, only such microorganisms can be used for sewage treatment.

There are four types of common sewage treatment strains, namely: nitrifying bacteria, denitrifying bacteria, composite sewage treatment bacteria and COD degrading bacteria.

Nitrifying bacteria are aerobic bacteria that exist in aerobic ponds or contact oxidation ponds, mainly to convert ammonia nitrogen from wastewater to nitrate. Denitrifying bacteria and nitrifying bacteria are good "partners" to denitrify the mixture that flows back from the aerobic tank.

The composite strains mainly should be launched in the new sewage system, helping the sewage biochemical talk tank to quickly cultivate microbial strains, with the effect of degrading COD, BOD, ammonia nitrogen and total nitrogen, its adaptability is strong, the impact resistance is strong, the stability is relatively good, and it has a certain removal ability for complex industrial wastewater, and the salinity tolerance of the strains after acclimation can reach 2%.

Finally, COD degrading bacteria are mainly used in biochemical tanks, and they have four common functions of hail bumps, namely: improving the removal rate of COD, improving the stability of the treatment system, improving the impact resistance and shortening the commissioning or restart cycle.

The advantages of strains used in the operation of sewage treatment equipment mainly include the following five aspects:

First, there are various types and a wide range of coverage. Different sewage treatment strains can effectively remove BOD, COD, ammonia nitrogen and other indicators in wastewater.

Second, it has strong stability, short cycle of circular culture, and strong adaptability. The solid powder strains have strong adaptability to the high and low loads of water quality, can be well cultivated and reproduced, and degrade the organic matter in the sewage.

Third, it has the functions of deodorizing, purifying water and promoting ecological balance.

Fourth, it is simple to put and has strong reproductive ability. Most of the strains propagated from the first generation to the first.

Second, the third cycle is very short, and the recovery ability to the impact caused by high load water quality is also relatively strong. Among them, the biological contact oxidation method can quickly hang the film for 3-7 days.

Fifth, for low-concentration heavy metal pollution, it can be removed by enrichment.

The most suitable pH value range for nitrifying bacteria in rural sewage treatment facilities is between, and the temperature control is the most appropriate at 22 -35, if the temperature is higher than 60 or lower than 10, the bacteria may be denatured or inactivated, which is one of the reasons why the sewage treatment equipment in the north should pay attention to thermal insulation in winter.

Dissolved oxygen is also an important factor affecting the reproduction of bacteria, for the good filial piety to change the oxygen bacteria, sufficient oxygen can ensure the ability of microorganisms to efficiently degrade pollutants, generally speaking, the amount of dissolved oxygen in the aerobic zone should be kept at 3-6 milliliters.

In terms of salinity, generally speaking, nitrifying bacteria in sewage treatment are used in both seawater and freshwater, and they have different salinity application ranges. Too high or too low salinity will affect the growth and reproduction of bacteria, biochemical effects and other clever judgments.

Finally, we need to store the culture in a cool and dry place for daily storage, especially not with toxic substances. Of course, if the sewage we treat contains toxic substances, we must pay attention to the pretreatment of the sewage in advance, and the toxicity has a strong inhibitory effect on microorganisms.

It is a kind of microbial bacteria for the treatment of sewage, and the mainstream ones on the market are Gandu nitrifying bacteria, Gandu compound bacteria, Gandu denitrifying bacteria, Gandu photosynthetic bacteria, etc.

Sewage treatment bacteria mainly use the principle of microbial degradation to decompose the organic matter in wastewater.

Secondly, the indicators of COD, ammonia nitrogen, BOD and total nitrogen in wastewater can be reduced.

Hello this friend! The main role of sewage treatment bacteria is to decompose organic matter in sewage. It is mostly used in the anaerobic and aerobic stages of sewage treatment

1. The anaerobic stage is mainly to add the third generation of anaerobic bacteria denitrifying bacteria to degrade COD, accelerate the hydrolysis and acidification process, and improve the treatment efficiency.

2. The aerobic section is mainly to add aerobic bacteria to the third generation of nitrifying bacteria, the main role is to degrade ammonia nitrogen and part of COD, and the strong sewage treatment bacteria will efficiently remove ammonia nitrogen, so that the effluent can meet the discharge standard.

Microbial sewage treatment strains have the characteristics of rapid reproduction, strong vitality, safety and non-toxicity, and microbial sewage treatment strains can effectively eliminate the problem of foul odor, prevent the breeding of pathogenic bacteria mosquitoes and flies, and solve the problem of water pollution.

1. It has the following characteristics.

1: Zero sludge sewage treatment technology, in one fell swoop to tackle the pain of sludge discharge in the sewage treatment process.

2. It has super strong removal of BOD, COD, SS, ammonia nitrogen, phosphorus and other polluting substances, with an effective rate of more than 90-9%%.

3. The effluent of the secondary sedimentation tank can directly reach the national first-class A standard or related standards.

4. Deal with dyes, dyeing and finishing wastewater and other wastewater with difficult to eliminate colors, and put it can be directly decolorized.

5. It has a significant deodorization effect, and has a strong ability to eliminate NK3, P, H2S and organic acids.

6. Once released, there is no need to continuously add strains after the system is stable.

7. Sewage treatment strains are easy to cultivate, reproduce quickly, have strong adaptability to the environment and natural evolution, once new polluting compounds appear, they can also gradually produce new enzyme systems through spontaneous or induced production, with new metabolic functions, so as to degrade or transform new compounds.

2: In 2015, condensing the crystallization of 27 years of wisdom of Defeng Biology, by the painstaking research of many water treatment experts of the company, the water treatment bacteria of [zero sludge discharge technology] were launched: nitrifying bacteria, denitrifying bacteria, and composite strains, which tackled the major problems of sludge discharge in the sewage treatment process in one fell swoop, and the product has many obvious advantages such as ultra-high efficiency to remove COD, ammonia nitrogen, phosphorus, SS and other polluting substances, and there is no need to continuously add bacteria after the system is debugged and stable, and has become a milestone in microbial sewage treatment technology.

The environmental industry must be cautious about the reference to "zero sludge technology", and so far, there is no system that does not produce sludge.

Strains are cultivated from the genes of a variety of microorganisms with excellent degradability to water pollutants, and are cultivated into a new generation with more internal degradable pollution.

After strict screening and domestication, a variety of microorganisms are formed into a biological chain using a special formula, and finally domesticated into a composite flora specializing in the treatment of complex sewage.

After the increase of strain concentration, more organic matter is adsorbed and absorbed by the strain, part of which is assimilated into cellular matter to help the strain proliferate, and the other part is continued to be decomposed into simple inorganic substances such as CO2, H2O, SO42, NH3, PO43 and other simple inorganic substances and energy release, which can achieve the purpose of sludge reduction. At the same time, bio-1 has strong adaptability to the environment and natural evolution, once a new chemical pollutant appears, they can also gradually produce new enzyme systems through spontaneous or induced production, with new metabolic functions, promote the decomposition of macromolecular organic matter in sewage, including dead microorganisms, into small molecule organic matter, and release soluble oxides. These small molecule organic compounds can be used by a variety of microorganisms to achieve the purpose of sludge reduction.

In addition, bio-1 is used in combination with filler to form a biofilm, and the sludge reduction effect is more obvious, and the sludge removal rate can reach more than 90%.

In order to achieve the purpose of degradation of pollutant substances in sewage, it is one of the most advanced methods in sewage treatment technology to select, cultivate and combine microbial bacteria that have special degradation ability of sewage to form a bacterial response group and become a special sewage treatment strain.

The strains originate from nature, are artificially cultivated and domesticated, and finally return to nature, serving as the mission of repairing the nitrogen cycle in water bodies, in line with the principles of non-toxic, pollution-free, non-secondary pollution, and harmless to the human body. It can effectively remove ammonia nitrogen, BOD, COD, SS, nitrate, sulfate, color, odor, toxic substances, chemical pollutants, etc., without the process of chemical coagulation and coagulation.
