What deodorant to use in the sewage treatment plant

Generally, plant liquid deodorant is used, and the purifier can be diluted and sprayed 200 times, which is quick and easy to use.

Different sewage has different pollution components. For general sewage treatment - plant deodorant, it is necessary to choose a high-powered concentrate, so that the amount added is small and the cost will be low.

Generally, biological deodorization technology can be used, but I haven't heard of using deodorant every day, but the cost is too high.

The best deodorant is a plant extract deodorant, and I am well aware of this.

Sludge deodorization, with plant deodorant, less addition, easy to operate, quick effect, very easy to use.

Sewage deodorant for sewage deodorization.

Method: Add the deodorant directly to the sewage according to a certain proportion to remove the odor.

Deodorants are used, and plant deodorants or biological deodorants can be selected according to the process.

Sewage treatment plant deodorization method: 1. The biological filter deodorization biological filter mainly includes two parts: pre-washing section and biological section. The odor collected by the induced draft fan is pre-washed in the pre-washing section (part of the pretreatment also includes temperature regulation, particulate matter removal, etc.), and then enters the biological section for the treatment of odor pollutants.

The pollutants in the gas diffuse from the main body of the gas phase to the water film on the outer layer of the filler, which is absorbed by the filler and finally degraded into carbon dioxide, water, etc. The treated gas is discharged from the top of the biofilter. The packing layer of the biological filter is adsorbent filter media (such as soil, compost, activated carbon, etc.).

2. The main body of the biological trickling filter is a packing tower with one or more layers of packing, and the surface of the packing is a biofilm several millimeters thick formed by microbial flora. The liquid containing the soluble inorganic nutrient solution is evenly sprayed on the packing from the top of the column, and the liquid flows from top to bottom, and then discharged from the bottom of the column and recycled. The organic exhaust gas enters the biotrickling filter tower from the bottom of the tower, and is purified by contact with the wetted biofilm during the ascent process, and the purified gas is discharged from the top of the tower.

3.The deodorization mechanism of plant extract deodorization is that the odor molecules in the odor are sprayed and adsorbed by the droplets of plant extracts scattered in the space, and various reactions occur at room temperature to produce odorless and non-toxic molecules. Natural plant extract is a plant deodorant formed by microemulsification of oil, juice, or extract extracted from flowers and trees in nature, which can be completely biodegradable, non-toxic, harmless, non-polluting, can eliminate odor, and can play a role in acidic, alkaline, neutral and other pollutants, and can effectively remove odorous gases.

Sewage treatment plants generally include the collection, discharge, filtration, purification and degradation of organic matter of sewage, among which odor treatment is an indispensable item. Normally, there are many methods for deodorization of sewage treatment plants, mainly chemical, biological, physical, photocatalytic and other methods. (1) Chemical method:

This method is mainly treated by internal chlorination method and oxidative deodorization method. The main principle of the internal chlorination method is to oxidize the organic matter in the water with the help of chlorine atoms, so as to remove the organic matter in the sewage, and the oxidation deodorization method mainly uses oxygen and reciprocal agent to oxidize the unsaturated organic matter (odor) into harmless products. (2) Biological Method:

This method mainly uses the nutrient absorption of microorganisms to dissipate the odor in the sewage, so as to achieve the purpose of eliminating the odor of pollutants. Biotechnology, such as biochemical oxidation in anaerobic treatment (BCO), can improve ammonia nitrogen, organic matter, etc. in sewage, reduce its odor, and also degrade sewage. (3) Physical Law:

This method mainly uses pressure changes or heat gradients to condense and separate the organic matter in the sewage, thereby reducing the odor of the organic matter in the sewage, and is also an effective anaerobic treatment method. (4) Photocatalytic method: This is a relatively new odor treatment technology, which mainly decomposes organic matter such as organic matter and odor in gas into carbon dioxide and water through photocatalyst, so as to degrade harmful odor.

In addition, there are a number of recommended measures that can be taken to protect the anaerobic system on the wastewater treatment plant, such as the proper installation of filters.

The deodorization method of the sewage treatment plant is as follows: biological filter deodorization, biological drip filtration deodorization, and plant extract deodorization.

1. Deodorization of biological filter.

The biological filter mainly includes two parts: the pre-wheel code washing section and the biological section. The odor collected by the induced draft fan is pre-washed and then enters the biological section for the treatment of odor pollutants, and the pollutants in the gas diffuse from the main body of the gas phase to the water film on the outer layer of the filler, which is absorbed by the filler, and finally degraded into carbon dioxide, water, etc., and the treated gas is discharged from the top of the biological filter.

2. Biological trickling filtration and deodorization.

The main body of the drip filter tower is a packed tower with one or more layers of packing, the surface of the packing is a few millimeters thick biofilm formed by microbial flora, the liquid containing soluble inorganic nutrient solution is evenly sprayed on the packing from the top of the tower, the liquid flows from top to bottom, and then discharged from the bottom of the tower and recycled, and purified by contact with the wetted wax culture biofilm during the ascent process.

3. Deodorization of plant extracts.

The deodorization mechanism of plant extracts is that the odor molecules in the odor are sprayed and dispersed in the space of the plant extract droplets adsorbed, and various reactions occur at room temperature to produce odorless and non-toxic molecules, natural plant extracts are plant deodorants formed by microemulsification of oil, juice, or extract extracted from flowers and trees in nature, which can be completely degraded by biology.

Sewage treatment safety measures and precautions:

1. Before cleaning the sewage pool, the sewage inlet valve should be closed, the sewer should be dredged, and the sewage in the pool should be drained as much as possible, and the sewer should be dredged once about how much, and natural ventilation should be maintained for more than 24 hours. If mechanical cleaning can be used, manual cleaning should not be used as much as possible.

2. Workers under the pool must be in good health and conscious, under the age of 18 and those with respiratory tract and allergies, as well as women are not allowed to engage in this type of work.

3. The sewage pool cleaning operation must fill in the "sewage pool cleaning operation sheet" by the safety responsible person to determine the on-site safety personnel, and the operation order must be made by the on-site safety officer to the sewage cleaning operation personnel to make technical and safety disclosure, and both parties should sign the "sewage pool cleaning operation sheet".

4. Personnel who go down to the pool must wear corresponding protective equipment (gloves, safety helmets, safety belts, safety ropes, oxygen tanks and toxic gas alarms) and be inspected by the on-site safety officer before operation.

Hello dear, <>

<>I'm asking a question and answer the main life blogger Komatsu: Biological treatment method: use microorganisms to decompose organic matter and reduce organic odor.

This method usually includes activated sludge method, biofilm method, aerobic granular sludge method, etc. Adsorption method: The adsorbent is added to the sewage group to remove the odor through chemical reaction or adsorption.

The adsorbent can be activated carbon, zeolite, activated clay, etc. Chemical oxidation method: By adding chemical oxidants to the sewage, such as hydrogen peroxide, ozone, etc., the organic matter is decomposed into harmless water and carbon dioxide, and the purpose of deodorization is achieved from Kaihe.
