Sewage tank cover deodorant several forms of effluent cover deodorization of several forms up to now, effluent cover deodorization has been widely suffered by many people. The sewage treatment plant will produce odor-producing by-products at the same time as sewage treatment. The main components of odor are hydrogen sulfide (H2S), ammonia, and tetrathiols, mainly from decomposed sewage and sludge. H2S will have a small amount of oxygen in the air to become SO2, and 30% of the SO2 in ordinary air is converted by H2S. Up to now, the sewage treatment plant deodorization waste gas treatment process can be divided into two categories: reference adsorption method and combustion phenomenon method.
1. The chemical deodorization method uses chemical media (NaOH, NaCl or NaClO) to react with inorganic odorous components such as H2S and NH3, thus achieving the goal of deodorization. This method is more thorough and faster for H2S, NH3, etc.
2. Activated carbon adsorption deodorization method is a unique place to use activated carbon to adsorb odorous substances in odor. In the adsorption tower, various activated carbons of different properties are set. After odorous things are contacted with various activated carbons, the sewage pool cover is used. The adsorption tower is discharged to achieve the goal of deodorization. After the activated carbon reaches the maximum limit, it needs to be regenerated or exchanged by hot air, steam or NaOH.
3. Combustion phenomenon The deodorization method has a direct combustion phenomenon method and a coal combustion phenomenon. The sump cover is based on the unique place of the odorous thing. Under the condition of a certain temperature and contact time, the odor is directly burned to achieve the goal of deodorization.
4. The living material method is to degrade the odor in the air through a membrane of living matter attached to the filler. The living material membrane grows, matures and reaches the degradation of living matter. The empirical process is alive. The process of material cultivation. The nutrients required for the micro-living matter in the living material membrane are derived from the organic compounds in the sewage, and the sewage pool cover is sprayed by the raw sewage for the sewage treatment plant as generally considered appropriate. The deodorization tank empty pool has a residence time of 1-3 min (visible odor liquid concentration variation), and the intake air flow rate is 2-3 m/s. The advantage of this approach is that the management of the situation is enhanced, the processing effect is satisfactory, and the operating costs are very low.
5. The effluent tank cover soil deodorization method is to put the gas together and then enter the bottom of the deodorization tank through the pipeline and profile it in the raw soil (the soil is naturally produced by soil and humus), and the sewage The odor of the pool cover is adsorbed by the surface of the raw earth particles during the process of soiling, and various odorous substances are trapped. Through the period, the micro-living substances for odor-producing things can be gradually developed on the surface of the granules, and the odor-producing substances can be continuously decomposed to complete the deodorization. At the same time, the appearance of the soil deodorization tank can be naturally grown or artificially planted to form a satisfactory background effect. The advantage of soil deodorization is that it has low investment, low operating costs, and can be beautified with the plant area, without any byproducts sprouting.
