Integration of water recycling equipment
     Integration of water recycling equipment is to reuse treated water concentration of several units within a single device, which is characterized by compact structure, small size, high degree of automation, the average capacity of less than 1500 tons / Days, mainly applicable to a single building sewage treatment, the general population of less than 3,000. When the water quantity and water quality in more volatile, the need to set a certain volume regulation pool, then adjust the pool structure is generally not included in the water reuse equipment。Common equipment as follows:

 (1) assembled in the water reuse equipment
     Section of the different treatment processes designed monomers, such as pre-processor, single aerobic treatment, anaerobic treatment of monomer, monomer flotation, depending on the depth of the water quality and treatment requirements, select a different monomers Connection, as building blocks to fight to form a complete process. This equipment is designed according to the situation on the ground type or buried; material can be reinforced concrete, steel can be applied (to do corrosion) or glass fiber reinforced plastic and other materials. Currently， sales of such equipment has been finalized。
  (2) MBR bioreactor
     Membrane bio-reactor, also known as MBR, is the membrane separation technology and biological treatment process of combining the development of new systems. Membrane structure from the overall point of view，and by the membrane bioreactor composed of two parts，used in membrane bioreactor wastewater treatment process is a membrane or membrane ultrafiltration，hollow fiber structure type to use more Type, flat and so on. Currently，sales of such equipment has been finalized。
     Membrane bioreactor has several advantages： good water quality, easy to control process parameters，equipment is compact，easy to automatic control and management。

【Conclusion】

Water is the survival of human society, the most important material conditions，shortage of water resources in China as a country, per capita water resources of 273 cubic meters，only the World per capita consumption of 1 / 4，water shortage has become Constraints of urban sustainable development an important factor。The current growth of recent developments in our country，urban water consumption increased significantly， increased pollution, leading to severe water shortages the city. Therefore, water reuse treatment technology is a long time China's current and future focus on the promotion of new technologies,new processes。
