What happens if the dissolved oxygen in the aerobic pool is too high for a long time

Aerobic sludge oxidizes itself and the sludge turns white in color.

The aerobic sludge gradually ages, the structure is loose, the colloidal mass is thin, the filamentous bacteria increase, the rotifers multiply in large quantities, the supernatant is finely crushed, the treatment effect becomes worse, the effluent becomes turbid, and the color of the effluent will become darker (the broken bonds after anaerobic treatment will be relinked under high oxygen oxidation).

High levels of dissolved oxygen in anoxic ponds are usually caused by sediment build-up at the bottom.

These deposits can be biological slurries, organic compounds, waste materials, and other substances. This results in a lack of oxygen** residue at the bottom of the anoxic pond, and it can also impede flow and disrupt water circulation.

To solve this problem, the following measures can be taken:

1.Sediment removal and disposal. The bottom of the anoxic pond should be cleaned regularly to remove sediment and mud. Some highly effective cleaners and agitators can promote the decomposition and dissolution of sediments and increase the oxygen level in the pool.

2.Maintain a good flow of water. In order to prevent the accumulation of sediment at the bottom, the water flow must be maintained well. Increasing water flow can improve oxygen supply to the bottom of the pond and increase the level of dissolved oxygen in the anoxic pool.

3.Control the input of organic compounds. Organic compounds can reduce the level of oxygen in the pool, therefore, the input of organic compounds must be controlled to reduce the burden on the anoxic pool.

4.Increasing oxygen levels in hypoxic ponds through biological treatment. By increasing the number of oxygen-producing fungi in the anoxic pond, the organic matter in the water body can be effectively treated and the water body can be cleaned.

When dealing with the problem caused by excessive dissolved oxygen in the anoxic pond, the above measures should be comprehensively used in the base mu, and different measures should be taken to solve the problem according to the actual situation.

At the same time, dissolved oxygen levels should be measured regularly to ensure that the water quality of the anoxic pond remains good.

Anoxic pond refers to the situation where the concentration of oxygen in the water does not meet the oxygen required for the metabolism of aquatic organisms. If the dissolved oxygen in the anoxic pond remains high, the main reason may be over-arubinized fertilization, industrial pollution, etc. Here are the suggestions to solve this problem:

1.Reduce pollution sources: control the discharge volume and discharge time of pollution sources such as agricultural fertilizers and industrial sewage, and reduce the production and occurrence of pollutants and the impact on the environment.

2.Oxygen enhancement treatment: The way to provide oxygen to the water body can be to increase the amount of oxygen in the water body by installing fans, oxygen aeration equipment, etc., to promote the redistribution of oxygen in the water and increase its solubility, and to increase the dissolved oxygen content of the water body.

3.Strengthen environmental protection publicity: strengthen the publicity and education of ecological environmental protection knowledge, improve the public's awareness of environmental protection, advocate low-carbon, low-pollution, sustainable development model, and jointly protect the environment.

4.Organize ecological restoration: Ecological restoration is carried out by planting vegetation, building truncated beams and making sewage ditches, etc., to improve water quality, promote the internal oxygen balance of water bodies, reduce the concentration and turbidity of harmful substances, and improve the stability and health of water ecosystems.

If the above suggestions are properly implemented, it can effectively improve the problem of high dissolved oxygen in anoxic ponds, promote biological growth and protect the ecological environment.

Hello is the lack of biological populations in the anoxic pond or.

Poor ventilation of the anoxic pool needs to be based on not.

In the same situation, different methods of dealing with the dismantling of the Qin Deficiency are adopted. i.I am glad that increasing the number of jujubes in the anoxic pond can solve your problem.

Summary. Alkalinity has a great impact, and insufficient alkalinity in aerobic processes will cause pH to drop, and too much drop will be detrimental to microbial growth.

Alkalinity has a great impact, and insufficient alkalinity in aerobic processes will cause pH to drop, and too much drop will be detrimental to microbial growth.

Generally, the alkalinity of the aerobic pool is less than 70mg L, which is normal, and the volume of the anoxic pool can be increased to increase the alkalinity of the first reserve. When the amount of nitrified ammonia nitrogen is required to be large, Kebu is suspected of being placed in a multi-stage anoxic aerobic form.

Effect of water depth: The higher the water level, the higher the dissolved oxygen due to the greater the contact area with oxygen in the atmosphere. 3. The influence of the turbulent degree of water:

Under the condition that other conditions (such as the temperature, density, viscosity of water, etc.) remain unchanged, the greater the flow rate of water, that is, the greater the turbulence of water, the more conducive to the dissolution of oxygen in the atmosphere in water, so the dissolved oxygen in water will increase. I hope mine can help you, if you are satisfied with my service, please give a thumbs up, I wish you all the best!

Summary. Hello, happy to answer your <>

1.What is the cause of sludge swelling in aerobic ponds? The dissolved oxygen in the aerobic pond is low or high for a long time (it is possible) The sulfide content of the raw water or anaerobic effluent is too high, resulting in the proliferation of sulfur bacteria, the load of the aerobic pond is low or high for a long time, the water temperature of the aerobic pond is high, the nutrient is unbalanced or lacks nutrients (N, P is low), and the pH value of the inlet water is a problem.

2.What are the causes of insufficient dissolved oxygen in aerobic pools? The concentration of sludge in the aerobic pond rises rapidly or the oxygen consumption increases due to the aging of the sludge, there are many suspended solids in the effluent of the anaerobic pond, and a large amount of dissolved oxygen is consumed after entering the aerobic pond, the blower fails to stop running or the fan pressure is not enough (this situation is rare), and the COD of the effluent of the anaerobic pond suddenly increases a lot ,..

Hello, it's a pleasure to answer <> for you

1.What is the cause of sludge swelling in aerobic ponds? The dissolved oxygen in the aerobic pond is low or high for a long time (possibly) The sulfide content of the raw water or anaerobic effluent is too high, resulting in the proliferation of sulfur bacteria, the load of the aerobic pond is low or high for a long time, the water temperature of the aerobic pond is high, the nutrient is unbalanced or lacks nutrients (N, P is low, and the lead remainder is clear) The pH value of the inlet water is a problem.

2.What are the causes of insufficient dissolved oxygen in aerobic pools? The concentration of sludge in the aerobic pond rises rapidly or the oxygen consumption increases due to the aging of the sludge, there are many suspended solids in the effluent of the anaerobic pond, and a large amount of dissolved oxygen is consumed after entering the aerobic pond, the blower fails to stop running or the fan pressure is not enough (this situation is rare), and the COD of the effluent of the anaerobic pond suddenly increases a lot ,..

3.What is the reason for the disintegration of sludge in the aerobic pond and the phenomenon of fine sludge crushing in the supernatant? The sludge load of the aerobic pond is small, the aeration is excessive, the sludge is self-oxidized, the flocculation of the sludge becomes poor, the sludge structure is loose (clear, there is more fine sludge, and the COD is not high), the sludge of the aerobic pond is too large and the sludge adsorption performance is too large.

Manifestations of hyperaeration in aerobic ponds.

1.Performance: When the sedimentation ratio is done, the supernatant is turbid, the oxygen consumption of the sludge in the aerobic pond increases, and when the aeration stops, the dissolved oxygen suddenly drops, and the water is suspended.

2.Impact: The water is dismantled and shouted that the COD is not up to standard, and it is turbid.

3.Causes: Insufficient or unbalanced nutrition, long mud age.

4.Countermeasures: timely replenishment of nutrients to ensure c:

n: p=100:5:

1. When the sludge concentration is high, the sludge should be discharged.

What is the reason for the foam in the aerobic pool.

1.Performance: The supernatant is turbid when the sedimentation ratio is done, the oxygen consumption of the sludge in the aerobic pond is increased in the open and loud, the field is excited when the aeration stops, the dissolved oxygen suddenly drops, and the suspended matter in the water is discharged.

2.Impact: The effluent COD is not up to standard, turbid and cautious.

3.Causes: Insufficient or unbalanced nutrition, long mud age.

4.Countermeasures: timely replenishment of nutrients to ensure c:

n: p=100:5:

1. When the sludge concentration is high, the sludge should be discharged.

Why does the mud from the secondary sedimentation tank float to the surface of the water?

That's the right answer.

High dissolved oxygen in the aeration tank will lead to oxygen poisoning in activated sludge, resulting in an increase in COD in the effluent of the aeration tank.

Solution: Reduce the amount of aeration.

The aeration tank uses the activated sludge method for sewage treatment, and the pool provides a certain retention time of sewage to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the pool body, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular.
