Example Embodiment

[0017] Example 1

[0018] The preparation method of the trapezoidal wave bent PVC sheet of the present invention is a conventional technology in the industry, roughly as follows: fully mix the raw materials according to the formula ratio, and then put them into the feed hopper of the injection molding machine, and extrude them through a filler mold. Then, the injection molded biological filler is magnetized on a magnetizer to obtain the above-mentioned board of the present invention.

[0019] The formula is: PVC 98 parts, salt mud (SM) 0.5 part, polyvinyl alcohol 1 part, polyacrylamide 0.5 part, activated carbon 1 part.

[0020] Example 2

[0021] The preparation method of the trapezoidal wave bent PVC sheet of the present invention is a conventional technology in the industry, roughly as follows: fully mix the raw materials according to the formula ratio, and then put them into the feed hopper of the injection molding machine, and extrude them through a filler mold. Then, the injection molded biological filler is magnetized on a magnetizer to obtain the above-mentioned board of the present invention.

[0022] The formula is: PVC 95 parts, salt mud (SM) 1 part, polyvinyl alcohol 3 parts, polyacrylamide 0.5 parts, activated carbon 0.5 parts.

[0023] The plates prepared by the embodiments of the present invention are bonded to each other to form an attached figure 1 The filler shown, due to the frosted bumps on the surface, has a specific surface area more than 10 times larger than the traditional smooth structure.

[0024] For specific applications, the requirements are shown in Table 1:

Abstract

The invention discloses a marine tubular-type biofilm colonization filling material. The marine tubular-type biofilm colonization filling material comprises honeycomb straight channels composed by mutual superposition of a plurality of trapezoidal PVC sheets bended like waves; the cross sections of the straight channels shape like regular hexagons; the surfaces of the trapezoidal PVC sheets bended like waves are provided with a plurality of dull polish bulges; the trapezoidal PVC sheets bended like waves are provided with grooves, wherein the grooves are designed to be concave towards a direction vertical to the straight channels; the thickness of the trapezoidal PVC sheets is controlled to be 0.05 to 0.3mm; and the trapezoidal PVC sheets are composed of 85 to 98 parts of PVC, 0.5 to 5 parts of salty mud, 1 to 5 parts of polyvinyl alcohol, 0.5 to 4 parts of polyacrylamide, and 0.1 to 4 parts of active carbon. The marine tubular-type biofilm colonization filling material can be used for removing pollutants effectively; contact area with pollutants is large; pollutants can be absorbed as far as possible; complete pollution removing and water body purification are realized; and wall flow time is short.

Description

technical field [0001] The invention relates to the technical field of bio-films, in particular to a marine tube-type bio-film filler. Background technique [0002] Marine biological aquaculture, with the decline of feed, excrement and water circulation in the aquaculture pond, there are a large amount of carbon-containing organic matter and ammonia nitrogen in the water. If it is not removed in time, it will easily cause water pollution, which will have a serious impact on biological aquaculture. . [0003] At present, a kind of plastic pipe is widely used, and its structure is composed of multi-layer inclined pipes superimposed, and the surface of the plastic material is smooth. Although the above-mentioned structure is built to remove the pollutants in the above-mentioned water body to a certain extent, due to its smooth surface, the pollutants cannot effectively attach and form films when the water body passes through the pipeline, resulting in a low ability to remove p...
