Many netizens in consulting about sewage treatment equipment pictures today four article about this small make up on the Internet to find the picture of sewage treatment equipment related information, please follow look small make up the integration of village and town sewage treatment engineering of sewage treatment equipment is commonly used equipment, domestic rural is the most widely used AO process, MBR process and SBR process of this kind of integration device effluent can reach the town sewage treatment plant emissions standards '1 B standard, adaptability is very broad, relatively low cost is especially suitable for daily - 10 tons About 100 tons of low concentration domestic sewage treatment, in addition to the scenic area, such as organic integration of sporadic sewage such devices may be adopted SBR wastewater treatment equipment but the SBR method is a kind of intermittent active sludge method, drainage time is short and need to maintain the stability of activated sludge, often need to set up the water decanter, and water decanter of high technical requirements and has a great impact on the sewage treatment effect, and the rural sewage treatment system has often lack professional water treatment equipment and the maintenance of the images, restricted the promotion force tripod in the field of the law in the rural sewage treatment environmental protection recommended screening technology on the integration of rural domestic sewage treatment equipment main body, should combine when water quality, water quantity and economic factors such as comprehensive consideration and high cost of sewage wastewater treatment equipment shall have investment money spread by content quality, interactive comment, share, shandong hospital sewage treatment equipment and so on multi-dimensional score decision, the medal of the higher level ( ) , generation of sewage treatment equipment pictures form its on the platform of integrated performance, the better the second, and working principle of the sewage treatment process sewage equipment collection of 40 of wastewater treatment technology process flow diagrams such as equipment work images for efficiency, waste water sewage treatment equipment, sewage is used water collectively, different industry wastewater pollutants in composition is not the same, countries according to the different nature of the sewage make buried sewage treatment equipment made of different standards, to deal with to meet the requirements of the wastewater discharge standard before discharge, it is often said that the problem a: meet the requirement of discharging standard of our factory is the CASS process, when the aeration foam on the die is stained with mud were black, dissolved oxygen increases rapidly, muddy water, excuse me what reason be problem 2: the products of our company are in the process with reactive dyes for hydrolysis - 70% Contact oxidation ( HRT10h) , coagulation - Precipitation ( HRT4h) , oxidation pond, water On the static settling after) , COD is 150 mg/L, chromaticity, 200, used a variety of drugs ( Aluminum sulfate and decoloring agent, ferrous sulfate and lime) , because of the reconstruction project, coagulation dosing for 4 h after water, easy to color, but the cost is too high or cannot make COD colorimetric standard question 4: at the same time treatment station operation is normal, just started out of the water is not good, a tan, but it's good anaerobic effluent, after oxidation ditch is out of the water is not good, at the beginning of the oxidation ditch pond water with mud and water or a blond, don't know what to do, when the aeration liquid level bubble with a little green, now is to remove water colority problem five: I early treatment of printing and dyeing wastewater treatment process in regulating pool is + sink sink + 2 + + hydrolysis contact sand filter, the normal usually yellow or a little pink, sometimes appear blue, green, excuse me what reason be cause sometimes appear blue-green three, sewage treatment, sewage treatment equipment involves five kinds of primary treatment technology introduction, belong to the physical processing, mainly went into a state of suspended solid pollutants in wastewater, most physical treatment method can complete the requirements of the primary treatment through the whole process of the coarse screen raw sewage through the sewage pump after the ascension, through the grating or sand filter, the sewage treatment equipment of images into the grit chamber after sand washing wastewater treatment equipment, zhejiang after sand water separation of wastewater into the settling basin for the first time, the above as the primary treatment, the pond water into biological processing equipment, at the beginning of the activated sludge and biological membrane method, ( The aeration tank reactor of activated sludge process, such as oxidation ditch, biological membrane method including biological filter, biological rotating disc, biological contact oxidation and biological fluidized bed) , biological treatment of effluent into the secondary sedimentation tank, the second pond, the water is disinfected emissions or entering tertiary treatment, primary treatment end to this as the secondary treatment, tertiary treatment including biological denitrification and phosphorus removal, coagulation sedimentation, sand filtration and activated carbon adsorption, ion exchange and electrodialysis method compared with the general method of aeration and oxidation ditch with infrastructure investment, easy maintenance, stable treatment effect, good water quality, less sludge production, and better off N, P, to adapt to the impact load ability strong advantages, such as the reaction area generally in anaerobic and anoxic condition, organic matter in the activated sludge adsorption, the area also has the biological selection, inhibit the growth of filamentous bacteria, preventing sewage sludge into the first YanYangChi mixed with reflux sludge, under the action of facultative anaerobic bacteria fermentation, the waste water easy biodegradable macromolecular organic matter into small molecules can absorb phosphorus accumulating organisms ( Such as VFA)
