Problems solved by technology

[0003] At present, the commonly used fillers in China are honeycomb fillers, soft fillers, semi-soft fillers and composite fillers. Although these fillers can basically meet the processing requirements, there are certain problems in practical applications. Due to the small specific surface area, As a result, there are deficiencies in the film-hanging speed, the amount of film-hanging, and the tightness between the film and the filler.

Abstract

The invention relates to eccentric filler for an oxygen-deficient environment. The eccentric filler comprises an inner ring assembly, a cutter blade assembly and an outer ring assembly, wherein the outer ring assembly comprises a support ring and a filler ring; the filler ring is arranged on the outer side of the support ring; the inner ring assembly and the outer ring assembly are of both hollow circular rings; the inner ring assembly is arranged in the outer ring assembly and is connected with the outer ring assembly by the cutter blade assembly, wherein a central line of the inner ring assembly deviates from a central line of the outer ring assembly. According to the eccentric filler disclosed by the invention, the hydraulic stirring intensity can be increased, so that sewage is fully mixed with active sludge in an anoxic tank, and anoxic grapatternnt is increased, so that organic matters in water can be effectively treated, and a more efficient denitrification effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an eccentric packing used in an anoxic environment. Background technique [0002] In recent years, biofilm technology has been used in sewage treatment to meet the requirements of sewage upgrading, so as to alleviate the pressure of water treatment of enterprises and the pollution of sewage to people's living environment. In the biofilm method, the filler is the habitat for microorganisms, and its performance directly affects the treatment effect and investment. [0003] At present, the commonly used fillers in China are honeycomb fillers, soft fillers, semi-soft fillers and composite fillers. Although these fillers can basically meet the processing requirements, there are certain problems in practical applications. Due to the small specific surface area, As a result, there are deficiencies in the film-hanging speed, the amount of film-hanging and the tightne...
