Membrane bioreactor (MBR) technology is a biological treatment and membrane separation technology combining a new process, replacing the traditional process in the secondary settling tank, which can efficiently carry out solid-liquid separation to obtain directly the stability of the water . But also in the biological tanks to maintain a high concentration of microbial biomass, less surplus sludge process very effectively remove ammonia, suspended solids and turbidity of the water close to zero, the water to remove bacteria and viruses were significantly low energy consumption, Small footprint.

Biological contact oxidation
 Biological contact oxidation process developed in the nineteenth century, biological contact oxidation biofilm treatment technology used, usually two contact oxidation process, the structure of the whole process simple, easy maintenance, processing time is short, small footprint, does not Need to return the sludge, does not produce sludge bulking, the treatment effect stable, more flexible operation and a series of operational advantages, the treatment effect with a stable, simple, easy to manage, less sludge is running in a short time and so can be Features

The significance of water reuse:

 Water is the survival of all life on earth, an important and indispensable material, but also an irreplaceable natural resources, because the world population growth and socio-economic development, human water consumption surge, the original clean water by human Activities, pollution, the use of increasingly scarce water resources on Earth. Inadequate water supply to the urban-industrial cause great loss of life to city residents while many difficulties and inconvenience, it is necessary to accelerate the sustainable utilization of water resources, the rational allocation of water resources, alleviate the shortage of urban water resources. While the sewage water recycling is an important method of resource, which can reduce pollution of the environment, but also increase the amount of available water resources, with obvious economic, social and environmental benefits. Urban wastewater reuse is a necessary requirement of water conservation, and development of water, use water to achieve different quality of water is a practical way.
 In the United States, Japan, Israel and other countries, toilet flushing, gardens and farmland irrigation, road cleaning, car washing, the city fountains, cooling equipment, add water, have a lot of use in the water.

China is a water-poor countries, per capita is only 0.22-0.27 million m3, out in the world 88. Water use in China's environmental protection, water conservation, water pollution control, sustainable economic development can play an important role. However, there is no water in our use of special project, no special funds, but the policy guidance, water consumption in cities is based on varying degrees of water shortage in this city may be, in the scope and scale of water use the slow development of . In recent years, many people of insight are called for to make the greatest possible use of water, hoping that all the industries, businesses, residents have this awareness. Each new district, the school, the compound should be built sewage treatment and water use facilities, especially the larger water consumption industries such as petrochemicals, agricultural products processing enterprises, and power should be used more water, even fire it Kinds of short-term water, but also the use of water. In short, as long as water can not consider the use of the water, the water in the local digestion, reaching zero discharge of sewage, both energy conservation and emission reduction, nor is it too much trouble, even more important is the environmental pollution to a minimum, thereby achieving the landscaping Environment.
