Biological filler and biological filler machine comprising same

Abstract

The invention discloses biological filler and a biological filler machine comprising the same. The biological filler is prepared from the following components in parts by weight: 4-8 parts of polyvinyl alcohol, 6-12 parts of polypropylene, 1-3 parts of activated carbon, 2-3 parts of a lubricant, 1-2 parts of calcium sulfate, 0.05-0.5 part of magnesium sulfate and 1-2 parts of calcium chloride. Thebiological filler machine comprises a chassis; a groove is formed in a central portion of the chassis; the biological filler is arranged in the groove; the biological filler comprises a hollow frame-shaped sphere; a plurality of drainage grooves are formed at the periphery of the groove on the chassis; guide grooves communicating with the groove are arranged in the bottom of the drainage grooves;guide tubes extending into the inside of the biological filler are arranged in the guide grooves; and an upper cover matched with the chassis is arranged above the chassis. The biological filler andthe biological filler machine comprising the same not only have the characteristics of improving the activity of internal microorganisms, prolonging the life of the microorganisms, and improving the water purifying ability of the microorganisms, but also have the characteristics of accelerating the growth of the microorganisms and the film hanging speed, increasing the number of the film hanging,and enhancing the adhesion between a microbial film and a filler.

Description

technical field [0001] The invention relates to a biological filler, in particular to a biological filler and a biological filler composed of the biological filler. Background technique [0002] Microbial film is composed of microbial populations and their coated extracellular polymers and matrix network. They adhere to each other or to the surface of the carrier to form a layer of microbial film, which is often used in environmental protection such as sewage treatment and waste gas absorption treatment. . Biological fillers are divided into composite fillers, three-dimensional elastic fillers, porous suspension ball fillers, active biological fillers, etc., which are the habitats for microorganisms and the carrier of biofilms. Provide the surface and internal space for microorganisms to adhere to, so that the reactor can keep as much microbial mass as possible, and it also has the effect of intercepting suspended solids. Generally speaking, the rougher the surface of the ...

AI Technical Summary

Problems solved by technology

However, for biofillers with high roughness, after the biofilm is formed, the microorganisms in the internal biofilm are often in an environment with insufficient nutrient concentration and insufficient oxygen due to the barrier of the outer biofilm, which affects the growth of microorganisms inside the biofill. Activity, the lack of internal microbial activity leads to short microbial life, which seriously affects the ability of biological fillers to treat sewage, and the water purification capacity is low; for low-roughness biological fillers, although it can increase the activity of microorganisms in the internal biofilm, However, due to the small specific area, poor hydrophilicity and bio-affinity, the overall growth of microorganisms is limited, the speed of film formation is slow, the number of film formation is small, and the adhesion to fillers is insufficient.

Therefore, the existing high-roughness biological fillers have the problems of insufficient internal microbial activity, short life, and insufficient water purification capacity. Insufficient adhesion between fillers and insufficient water purification capacity
