Problems solved by technology

[0002] Biochemical treatment is the most widely used and relatively cost-effective treatment method among existing sewage treatment technologies. However, sewage treatment plants often need to consume huge investment and operating costs to provide oxygen for biochemical reactions, which are affected by temperature, pressure and water vapor. The combined effect of various factors such as the contact area, the dissolved oxygen in the water directly restricts the time and amount of sewage biochemical treatment required

Abstract

The invention discloses self-oxygenation microorganism degradation filler and a preparation method thereof. A product disclosed by the invention has a rapid film formation speed, strong biological adhesiveness, uneasiness of falling off and high treatment efficiency and is especially used for treating domestic sewage and industrial wastewater with relatively high BOD5 (Biochemical Oxygen Demand 5)content; the product disclosed by the invention has extremely strong hydrophilicity and biocompatibility; the filler contains an oxygen-carrying material and surface tension between air bubbles and awater surface can be reduced; oxygen can be dissolved into sewage and the growth of microorganisms is facilitated; the film formation time is shortened and the microorganism treatment efficiency is improved. The ammonia nitrogen removal rate is higher than 90 percent and the removal efficiency of COD (Chemical Oxygen Demand) exceeds 80 percent; compared with existing filler, the sewage with relatively high BOD5 content can be treated better.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a self-aerobic microbial degradation filler and a preparation method thereof. Background technique [0002] Biochemical treatment is the most widely used and relatively cost-effective treatment method among existing sewage treatment technologies. However, sewage treatment plants often need to consume huge investment and operating costs to provide oxygen for biochemical reactions, which are affected by temperature, pressure and water vapor. Due to the comprehensive effect of various factors such as contact area, the dissolved oxygen in the water directly restricts the time and amount of sewage biochemical treatment required. Existing ways to increase dissolved oxygen in water are mainly to pump a large amount of air through an air compressor to increase the number of air bubbles in the water to achieve the purpose of increasing dissolved oxygen in the water. Under the s...
