How to remove odors from wastewater that is reused in daily life

For workshops in different industries, Tianjin Yuanzhuo Environmental Engineering Co., Ltd. suggests that enterprises reduce the emission of volatile organic (VOCs) and various odorous gases from the source. Combined with the production efficiency and product performance of the product to study and solve, so as to achieve organized collection and reduce unorganized emissions; Strengthen waste gas collection measures, improve the efficiency of waste gas collection, classify and collect the waste gas generated by the process, collect all the waste gases, and reduce the fugitive emission and escape of waste gas. Regularly inspect and repair pipelines, valves, interfaces, pump bodies, etc. that are prone to leakage to minimize running, running, dripping, and leakage.

Combined with the characteristics of the industry and the needs of enterprises, Yuanzhuo Environment divides the waste gas odor treatment program into three treatment stages: collection, pretreatment and odor treatment. During the collection stage, it is recommended to increase the number of air exchanges and reduce the ,... exhaust gas concentration

Lime can purify water!

There is also bleaching powder, the kind used by water companies.

The simple one that doesn't cost anything. If you can't use up your water today, you will throw it away tomorrow. It would be nice to have today's wastewater. You won't be able to protect yourself from the sewer system. Buying fungicides is expensive. Are you willing?

Sprinkle a small amount of alum in a bucket to achieve the effect.

The best thing to do is to use up the water before it stinks, or throw it away as soon as it smells.

1. The sewage to be treated contains compounds that are volatile and odorous, and these compounds are volatilized by mechanical movements such as agitation and flipping by the equipment, resulting in odors;

2. In the process of transportation and storage, sewage releases peculiar odor due to the action of microorganisms;

3. In the process of sewage treatment, peculiar odor is generated due to process conditions and requirements. The odorous molecules produced in the sewage treatment process are mainly nitrogen-containing and sulfur-containing compounds, such as ammonia and hydrogen sulfide.

Wastewater can create odors in the air.

Wastewater contains a variety of withered chemicals, including volatile substances and odorous compounds. In the process of Virgin Penari wastewater, some volatile substances may be diffused into the air through the gaseous state, and no odor is generated. For example, hydrogen sulfide, methane and other gases are one of the odorous substances that may be produced in the wastewater treatment process.

In addition, in the process of biological treatment of wastewater, microorganisms such as bacteria will produce some odorous volatile organic compounds, such as phenols, aromatic oxides, etc. Odors can also occur when these compounds are not effectively controlled and treated.

Most of the odorous substances produced in the sewage treatment process are organic compounds, mainly composed of carbon, nitrogen and sulfur elements, such as: low molecular weight fatty acids, amines, ethers, halides, aliphatic, aromatic, heterocyclic nitrogen or sulfides. These substances all have active groups and are prone to chemical reactions, especially oxidation.

When the active group is oxidized, the odor disappears.

Chemical deodorization method: the irreversible chemical reaction between the odor components and the main components of the chemical solution is used to generate new odorless substances to achieve the purpose of deodorization; Depending on the composition of the odor, it is necessary to select the corresponding chemical agent. The main methods are:

Air oxidation, chemical oxidation, washing-adsorption (wet absorption oxidation), adsorption-oxidation, etc.

Biological deodorization: The process of using microorganisms to degrade or convert organic pollutants in odorous gases into harmless or low-harm substances. The main methods are: biological filtration method, soil method, packed tower biological deodorization method, adding Fanqing microbial deodorant, etc.

Ion deodorization method: When the air passes through the high-energy ion generator, the oxygen molecules are subjected to the deodorization equipment.

The emitted high-energy electrons collide to form oxygen ions with positive and negative charges, respectively. These positive and negative oxygen ions have strong activity, and after a series of reactions, the compounds containing C, H, and S elements will finally form small molecule compounds CO2, H2O, and SO2, and no secondary pollutants will be generated. And it can also effectively destroy the living environment of bacteria in the air and reduce the concentration of bacteria in the indoor air; After the ions collide with the tiny solid particles in the air, the particles are charged and produce a coagulation effect, so that the tiny particles that cannot be captured by the traditional filtration method and are harmful to the human body become trapped or settled by their own gravity, so as to achieve the purpose of purifying the air.

Plant deodorant can be used, domestic sewage has complex composition, many bacteria, and strong odor, plant deodorant can quickly remove odor and inhibit odor generation.

The simplest and safest way to deodorize sewage in life is to use plant deodorant, which can be sprayed after dilution to achieve the effect of deodorization, because domestic sewage is generally household sewage and wastewater after the use of various domestic water, after fermentation, a foul odor gas is formed, and the components of the odorous gas ammonia, hydrogen sulfide, methyl mercaptan, and other gases will have a great impact on the body, and Fanqing plant deodorant is a pure natural plant extract that does not have any effect on the human body, and at the same time can have the effect of antibacterial, the effect is very obvious. You can consult them for details.

This sewage odor has a great impact and it is okay to use plant deodorants.

(1) Spraying the deodorant, the method is to mask and deodorize, and use the fragrance of the deodorant to cover up the original odor of sewage, but it cannot fundamentally remove the odor in the sewage, which is a symptom but not a cure;

2) cover the sewage treatment structure, collect the waste gas in the sewage and concentrate on treatment, and the current waste gas treatment device comprises a chemical deodorization device and a biological deodorization device, and the effect is also OK.

Plant deodorant can be added to the sewage, and the deodorant molecules of the deodorant can react with odorous molecules such as hydrogen sulfide, ammonia, methyl mercaptan, methyl sulfide, etc., and turn them into odorless molecules, so as to achieve the effect of deodorization. Non-masking deodorization without polluting water quality, suitable for long-term use.

Plant deodorant can be used, which is simple and convenient to operate, and has a good deodorization effect on hydrogen sulfide, methyl mercaptan, ammonia and other foul odors in wastewater.

Use a plant deodorant, method 1: can be added to the wastewater, by 1/10000 to 1/10,000. 2: Add a spray device next to the sewage pool and dilute the deodorant 200 times to spray. (Suitable for large amount of wastewater, low treatment cost).

Hydrogen sulfide gas is the main source of odor in sewage treatment systems, and the compounds of metal and sulfur make the water appear black, indicating the presence of hydrogen sulfide gas in the water.

Odorous gases dissolved in raw sewage are released at the beginning of wastewater treatment. Many plants have successfully controlled odors from raw wastewater through chlorination. The dose is 5-10 mg l, and the dose is 15-25 mg l when the odor is severe.

In order to reduce odors generated in biological treatment systems, it is necessary to control the organic load in the water, which contains less than 10% of volatile substances in the effluent flow. If the limit is exceeded, immediately reduce the intake water and raise the pH with chemicals such as lime or alkali to reduce volatilization.

The occurrence of odor in the integrated living sewage treatment equipment is related to the collection, management process and operation of the management system. Odours occur on both the living effluent and the solids trapped by anaerobic microorganisms, which deprive organic matter, and the usual living effluent includes sufficient organic sulphur and inorganic salts. In many factories, chlorination has been used to successfully control the odor release of raw wastewater.

The dose is 5-10 mg l, and the dose is 15-25 mg l when the odor is critical

In order to reduce the odor that occurs in the biological management system of the integrated living sewage treatment equipment, the organic load in the water must be controlled, and the sewage flow contains less than 10% of volatile materials. If it is found that the standard is exceeded, immediately reduce the water intake and use chemicals such as lime or alkali to increase the pH to reduce volatilization.

The odor gas of the integrated sewage treatment equipment mainly occurs in the pre-treatment of raw sewage. The usual control method is to combine the demand for odor gases and the source of gas reduction.

The generation of odors is directly related to the collection, treatment process and treatment system of wastewater. Rural sewage is mainly domestic sewage, which produces odors on both domestic sewage and solids occupied by anaerobic microorganisms. These anaerobic microorganisms consume organic matter, sulfur and nitrogen.

Usually domestic sewage contains enough organic sulfur and inorganic salts. The components of odor include organic and inorganic molecules, and the two main inorganic gases are hydrogen sulfide and ammonia. Organic odors are usually the result of the activity of living organisms, which break down organic matter to form a foul odor composed of various organic gases.

Odor gases are mainly generated in the pretreatment stage. Through a pre-treatment process, odor gases are released into the air in the initial structure. Sewage contains many odor-producing substances, and since most of the rural sewage treatment adopts biological treatment methods, microorganisms will inevitably release odors when they decompose organic matter.

In order to reduce odors generated in biological treatment systems, the organic load in the water can be controlled and the volatile substances in the wastewater can be reduced. In addition, volatilization can be reduced by reducing the amount of water incoming and increasing it with chemicals. During the pre-treatment phase of the grate collection process, odors are generated, organic matter sticks to the grate and rots constantly, and the accumulated solids need to be removed regularly, and the grates must be cleaned and maintained in accordance with the maintenance manual and mechanical requirements.

Most of the rural sewage treatment projects use buried integrated sewage treatment equipment, and the project is not easy to produce peculiar smells when the project is completed. However, most of the rural sewage treatment projects have a design life of more than 15 years, and the corrosion problems of integrated sewage treatment equipment and pipelines are often closely related to the production of peculiar odors. Therefore, it is necessary to try to choose materials with a long life such as glass fiber reinforced plastic and polymer polymers.

Odor reduction depends not only on equipment and construction, but also on project budget expenditures, as well as equipment maintenance, space constraints, hazardous substance content and other factors. Therefore, rural sewage treatment requires the joint efforts of many parties in odor control.

Hope it helps.

The most common is the chemical treatment. It is also the most cost-effective treatment method so far, mainly because it is to add some chemical agents to oxidize the malignant substances in the sewage, and then completely decompose the substances in the odorous gas, so as to achieve the purpose of purification, and the efficiency of treatment is relatively high, which is applicable to most sewage treatment plants, but it is not easy to use the sewage containing chemical agents, because the chemical components contained in the sewage are likely to make the chemicals ineffective and fail to achieve the purpose of treatment.

There are also methods such as drying treatment. The most widely used is the activated carbon adsorption method, through the porous activated carbon to decompose the odorous components in the odorous gas, adsorption on the activated carbon substance, although the treatment efficiency is also relatively high, but the shortcomings are also more obvious, that is, the activated carbon needs to be cleaned regularly, otherwise it will lose its treatment capacity.

Then there is the plasma treatment method. Anyone who has studied physics knows that high-energy plasma has strong instability, and when combined with molecules in odorous gases, it will decompose molecules into carbon dioxide and water, and the energy conversion efficiency is very high, and the energy-saving type is also very good.

The use of plant deodorant, simple to use, can quickly remove odor, to many manufacturers to solve the problem of odor or odor can not be solved.
