A suspended photocatalytic biological treatment equipment

technical field

The utility model belongs to the technical field of environmental protection and energy saving, and relates to biological treatment equipment, in particular to a suspended photocatalytic biological treatment equipment.

Background technique

As the types of trace pollutants that can be measured in water sources and drinking water continue to increase, the research on slightly polluted water sources is also on the agenda. Now the treatment of slightly polluted water sources is mostly a combination of biotechnology and advanced treatment technology. The essence of water source water biological treatment technology is to remove biodegradable organic substances including humic acid in source water through microbial degradation, and to remove refractory biodegradable substances in water through advanced treatment. The development of various combined technologies is very effective for the removal of some refractory organic substances. Through efficient oxidation, most of the organic substances in water are removed, and the mutagenic activity of drinking water is effectively reduced. However, these methods and equipment are relatively complicated, and the requirements for operation and operating conditions are relatively high, especially the cost problem seriously restricts their popularization and use.

Photocatalytic technology has the characteristics of non-selective degradation, and is widely used to degrade refractory organics, but the treatment cost is high. Biological treatment of sewage is the most common sewage treatment technology at present. It has the characteristics of low cost. However, due to the selective degradation of microorganisms, some refractory biodegradable substances are not treated and discharged into the environment, which affects human health and well-being. Survival environment. Combining the two methods can achieve better results for the treatment of slightly polluted water source wastewater.
