Suzhou Biyuan Environmental Protection Engineering Co., Ltd. Desilting is one of the effective measures to eliminate endogenous and control water pollution. There are two main methods to treat wastewater from silica. One is dry cleaning (dry cleaning), that is, dry cleaning after the lake water is drained. Taking the riverbed scouring and dredging technology of Liwa River in Shanghai as an example. The other is mechanical feed to remove the sludge in the water. The usual tool is a dredger. Dry sand discharge refers to the discharge of black water and smelly water from the city to expose the sludge at the bottom of the water body, and the use of hydraulic flushing to clean the sludge. In the treatment of white carbon black wastewater, dry sedimentation has the advantages of high sediment concentration, fast sediment settling speed and thorough sediment settling, but it also has the disadvantages of destroying the original ecology of water body and generating secondary pollution. In the actual construction, the urban box culvert dredging, open channel dredging and small lake dredging are usually carried out by the dry method, with simple equipment operation, convenient transportation and obvious black and smelly water treatment effect.
In the treatment process of black and odorous water body, we should learn from the foreign treatment methods, and the white carbon black wastewater treatment of manufacturers should ensure the feasibility and effectiveness of black and odorous water body treatment. Specifically, the future development of black and odorous water treatment can be started from the following aspects: first, the point source treatment needs to strengthen the application of science and technology in the future development, and the treatment of white carbon black wastewater actively adopts various leading technologies, such as vacuum collection and other technologies; second, the non-point source treatment needs to be carried out under the comprehensive related collaborative technology, so as to realize the treatment of white carbon black wastewater At present, the control of pollution; the third is the internal control, which needs to shift the focus to various new materials, such as various oxidants and covering agents.
Denitrification and dephosphorization detailed introduction: denitrification in wastewater biological treatment mainly relies on some specific bacteria to realize the transformation of nitrogen form. Nitrogen-containing organic compounds first decompose into ammonia nitrogen NH4 + or NH3 under the action of microorganisms. This process is called "ammoniation reaction". In white carbon black wastewater treatment, nitrifying bacteria convert ammonia nitrogen into nitrate, which is called "nitrification reaction"; denitrifying bacteria convert nitrate into nitrogen. This reaction is called denitrification. Nitrogenous organic compounds are eventually converted to nitrogen and removed from sewage.
The surface of hydrophobic particles is easy to attach bubbles in the treatment of white carbon black wastewater, so the air flotation method can be used. Hydrophilic particles can be turned into hydrophobic after being treated with appropriate chemicals. In the air flotation process of water treatment, coagulants are often used to make colloidal particles coalesce into flocs, which have network structure and are easy to intercept bubbles, so as to improve the air flotation efficiency. Furthermore, surfactants such as detergents can form foam in water, and also have the function of rising together with suspended particles. The sewage flows into the septic tank by itself and flows into the regulating tank after the floating and large impurities in the sewage are removed by the septic tank; the domestic sewage or the kitchen sewage treated by the oil separator is fully mixed in the regulating tank and pumped into the anoxic tank by the submersible sewage pump, and the water flows into the membrane bioreactor by itself, and the water flows into the backwash water tank, which can be discharged after being disinfected with chlorine tablets. In the treatment of white carbon black wastewater, only a small part of the sludge produced by the process is used as the automatic control system of reflux treatment to control the operation of water pump, reflux pump and fan, so as to realize the unmanned control of buried domestic sewage treatment equipment. The surface of suspended solids can be divided into hydrophilic and hydrophobic.
A good product comes from a good reputation. The first priority of a good sewage treatment equipment company must be to create products based on customer satisfaction and quality service. Therefore, relying on this situation, will create good social and economic benefits, with good service status. In addition, good manufacturers should improve their after-sales service, fully improve the details, and regularly do maintenance work to return the products. White carbon black wastewater treatment, because only in this way can better demonstrate the effectiveness of sewage treatment equipment, trust and goodwill steadily increase. The way to do this is to better serve the community and customers. A good sewage treatment equipment company should have such ideas and services, pay close attention to the buyer, and realize the real conscience manufacturing.
