Understand，China's environmental protection market total output value2012Year29908.7100 million yuan increase2015Year45531.7Billion，Among them, the wastewater treatment costs occupy a lot.，my country's sewage treatment industry penetration，Overall development is in a rapid growth period，Mainly manifested in rapid expansion of sewage treatment capacity、Sewage treatment rate is steadily improved、Rapid growth of sewage treatment。
2010Annual urban sewage treatment plant processing capacity10262Wanci square meters，Ratio2009Year-end growth13.4%，Urban sewage treatment rate reached76.9%。As of2011year9End of the month，National city city、County accumulated urban sewage treatment plant3077Seat，Treatment ability1.36One hundred million cubic meters/Day。
Data display as of2015year，National urban sewage treatment capacity has reached2.17One hundred million cubic meters/Day，Urban sewage treatment rate reached92%，County city sewage treatment rate reached85%，The construction of the national urban sewage treatment facilities is basically completed“Twelve Five”Planning objectives。Since the sewage treatment market is huge，It is directly affected by this series of sewage treatment equipment.，Constant innovation of modern technology、progress，Advanced instrument、Meter appearance，Make tap water plant、Sewage plant control automation is achieved，Providing powerful technical support for my country's establishment of a reasonable and effective sewage treatment system，The following is some major processing equipment。
Centrifuge
The centrifuge is mainly used to separate solid particles in the suspension from the liquid.；Or different densities in the emulsion，Differential liquids(For example, from milk to the cream)；It can also be used to exclude liquids in wet solids，For example, dry and wet clothes with washing machine；Special overspeed tubular separators can also separate different density gas mixtures；Features with different density or particle size of solid particles in liquid，Some settled centrifuges can also grade solid particles by density or particle size。
Microfilter
The microfilter is a drum screen filter device。The treated wastewater is in the bushing，Flow out of the screen with radiation radiation，Water impurities(Small suspension、fiber、Pulp, etc.)That is, it is cut into the drum on the mesh.。When the impurities cut on the screen are drumped to the upper portion，The pressure rinsing water is reversed into the slag tank.。Runtime，Drum2/5Diameter part exposed water surface，Revolution1-4r/min，Filter filter speed can be used30-120m/h，Rolling water pressure0.5-1.5kg/cm2，The amount of flushing water is produced0.5-1.0%，Used in reservoir water treatment，Algae efficiency40-70%，In addition to floating biological efficiency97-100%。Microfilm machine covers a small area，Has a large production capacity(250-36000m3/d)，Convenient operation management，Successfully applied to water supply and wastewater treatment。
Airfurbonic
Airfooter is a suspended matter in various industries and municipal sewers.、Equipment for grease and various gums。This equipment is widely used in refining、Chemical industry、brewing、Slaughter、Plating、Processing of industrial wastewater and municipal sewage of printing and dyeing。Divided according to the method of dissolving:Inflatable gas、Solumatizer and electrolytic airfront machine。The principle is to be difficult to dissolve gas or more than two or more different liquids in water.(Send fine bubble particle size20-50Micron)。Take micro bubbles as carriers，Impurity particles in adhesion water，The particles are flopped to the water surface and water separation.，To achieve solid-liquid separation。
Ozone generator
Ozone is a strong oxidizing agent，It can break up the macromolecule of organic matter into small molecules，Decompose the difficult solution into a soluble material，Transform the difficult degradation substance into degradable substances，Decompose hazardous substances into harmless，Thus the role of sewage purification。
Sewage treatment of ozone generator products“Ozone is excellent oxidant，Can completely decompose organics in sewage；It can kill all pathogenic microorganisms including viruses and spores, which have strong chlorine-resistant viruses and spores.；During the sewage treatment，SewagePHValue、Smaller effects。（source:Internet）
