How to use microorganisms to treat sewage?

With the development of industry, the composition of sewage has become more and more complex.  Some difficult to degrade organic materials and toxic substances, need to use the method of microbial treatment, sewage with microbial growth and reproduction conditions, so that microorganisms can get nutrients from sewage, degradation and use of harmful substances, so that sewage can be purified.  Wastewater biological treatment is a treatment method that uses the life activities of microorganisms to degrade organic pollutants in the dissolved or colloidal state in wastewater, so as to purify the wastewater.  Wastewater biological treatment technology is favored by people because of its low consumption, high efficiency, low cost, convenient and reliable process operation and management and no secondary pollution.  

Definition  

A method of removing organic pollutants from wastewater by using microbial metabolism, also known as wastewater biochemical treatment, referred to as wastewater biochemical method.  Due to the disadvantages of traditional treatment methods, such as high cost, complex operation, and difficult to deal with harmful pollution in large flow and low concentration, biological treatment technology has been paid more and more attention after years of exploration and research.  With the development of heavy metal-resistant microorganisms, the application of biotechnology in the treatment of electroplating heavy metal wastewater has shown a booming trend. According to the different mechanisms of biological removal of heavy metal ions, it can be divided into biological flocculation, biological adsorption, biochemical and phytoremediation methods.  

Features

1, using biological methods to remove organic matter is the most economical;  

2. 90% wastewater treatment process belongs to biological treatment process;  

3, water ammonia nitrogen with biological treatment method to remove the most effective;  

4, the vast majority of industrial wastewater is also based on biological treatment methods
