1, Sewage treatment program:
Sewage treatment according to its role can be divided into physical method, biological method and chemical method of three.
①Physical method: the main use of physical separation of non-soluble substances in the sewage, in the treatment process does not change the chemical nature. Commonly used gravity separation, centrifugal separation, reverse osmosis, air flotation. Physical method of treatment structures are simpler, more economical, used for village and town water capacity, self-purification ability, the degree of sewage treatment requirements are not high.
② biological method: the use of microbial metabolism, the sewage is dissolved or colloidal state of organic matter decomposition and oxidation into stable inorganic substances, so that sewage is purified. Commonly used activated sludge and biofilm method. Biological method of treatment is higher than the physical method.
3 chemical method: is the use of chemical reactions to treat or recover sewage dissolved substances or colloidal substances, mostly used for industrial wastewater. Commonly used are coagulation, neutralization, oxidation reduction, ion exchange method. Chemical treatment method is effective, high cost, mostly used as a biochemical treatment of the effluent, for further treatment to improve the quality of the effluent.
Sewage treatment can be divided into primary treatment, secondary treatment and tertiary treatment according to the degree of treatment.
Primary treatment is mainly to remove suspended solids in the sewage, commonly used physical method. Primary treatment of wastewater BOD removal rate of only 20%, is still not suitable for discharge, but also need to carry out secondary treatment. The main task of secondary treatment is to substantially remove the colloidal and dissolved organic matter in the state of sewage, BOD removal rate of 80% to 90%. Generally after secondary treatment of sewage can meet the discharge standards, commonly used activated sludge and biofilm treatment method. The purpose of tertiary treatment is to further remove some special pollutants, such as fluoride, phosphorus removal, etc., belongs to the depth of treatment, commonly used chemical method.

4, activated carbon deodorization seriesFeatures:
① Wintop-CD activated carbon deodorization equipment adopts the structure of tangential air outlet, circular filtration, intermediate air inlet, no feeding on the upper part and unloading at the lower part, which overcomes the shortcomings of the traditional activated carbon filters with high filtration resistance, small area, large floor space, high investment in equipment and difficulty in replacing the activated carbon and makes the structure design of activated carbon filtration equipment nearly perfect. The structural design of the filtration equipment is nearly perfect.
② Wintop-CD activated carbon deodorization equipment is equal to the volume of traditional activated carbon filtration equipment filtration area of 2 ~ 4 times, resistance is only the traditional 1/2 ~ 1/3.
