The FRP sewage pool cover is an effective device to inhibit the spread of odor, and it is naturally indispensable! The government attaches great importance to the priority areas and areas where the community population is relatively concentrated. Various programs should be adopted to remove gaseous pollutants cost-effectively, so that the sewage treatment plant can fundamentally achieve the purpose of benefiting the people.

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, haloalkanes, and aliphatic, aromatic, and heterocyclic nitrogens or sulfide, etc. These substances have reactive groups and are prone to chemical reactions, especially oxidation. When the reactive groups are oxidized, the odor disappears.

Chemical deodorization method: The irreversible chemical reaction between the odor components and the main components of the chemical liquid is used to generate new odorless substances to achieve the purpose of deodorization; due to the different odor components, the corresponding chemical agents need to be selected. The main methods are: air oxidation method, chemical oxidation method, washing-adsorption method (wet absorption oxidation method), adsorption-oxidation method, etc.

Biological deodorization method: 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, etc.

Ion deodorization method: When the air passes through the ion generating device, oxygen molecules are collided with electrons emitted by the generating device to form oxygen ions with positive and negative charges respectively. These positive and negative oxygen ions have strong mobility. After a series of reactions, compounds containing C, H, and S elements are formed into small molecular compounds carbon dioxide, water, and sulfur dioxide, and no secondary pollutants are produced; and they can also effectively It destroys the living environment of bacteria in the air and reduces 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 cause agglomeration effect, so that the traditional filtration methods cannot capture and are harmful to the human body. The particles become trapped or settle down by their own gravity to purify the air.

The ion generating device is used, and the air of positive and negative oxygen ions with controllable concentration is fed into the odor-emitting space with the help of the ventilation pipeline system, and the surface of the pollution source (such as sewage pool, etc.) is "covered" with the ionized air, so that the ions are in a very short time. It can react with harmful gas molecules within a certain time, restrain its diffusion and reduce its concentration, ensure that the operators on site work in a good environment, and can also reduce rust and prolong the service life of instruments and meters.
