Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment. More specifically, the present invention relates to a biological filler shaking bed and its application in wastewater purification.

Background technique

[0002] In recent years, newly-built sewage treatment plants have sprung up like bamboo shoots after a rain, but my country’s current sewage treatment technology is generally relatively backward, accompanied by many problems, such as large sludge production, difficulty in subsequent treatment, high energy consumption, and treatment. The effect is unstable, the sewage treatment plant emits an unpleasant smell, etc. It can be seen that many technical problems of the sewage treatment plant that have been built have not yet been resolved.

[0003] Contact oxidation method is a wastewater biochemical treatment method with both the characteristics of activated sludge method and biofilm method. It has a wide range of applications in my coun...
