Background

Modern technology, which has been getting more and more recognition in the world for the last several years, is the moving bed biofilm reactor (MBBR) technology. Currently, movable biofilters made of basic polymeric materials, polyethylene and polypropylene.

Methods

An innovative solution in the field, mainly because of the large active surface area for biological membrane can be wood polymer composites (WPC). In the research polypropylene (PP) and polyvinyl chloride (PVC) was used as the matrix. Two types of commercial wood flour also, selected from conifers, were selected for the study: Lignocel C 120 with particle sizes in the range of 70 μm–150 μm and L9 with dimensions of 0.8–1.1 mm and wood chips, which are used on an industrial scale for the production of chipboards, were used as a filler. A quantitative and qualitative analysis of newly formed biofilms was performed.

Results

The study showed a direct effect of the filler and its particle size on the susceptibility to the formation of the biofilm of on the composites surface.

Conclusions

Polypropylene PPH 648 T and 40% wt. of L9 type wood flour was the most susceptible to biofilm formation. Pure polypropylene PPH 648 T was the least susceptible material.

聚合物复合材料上的生物膜-定性和定量微生物分析

背景

移动床生物膜反应器（MBBR）技术是近几年来在世界范围内获得越来越多认可的现代技术。当前，由基本聚合物材料，聚乙烯和聚丙烯制成的可移动生物过滤器。

方法

木质聚合物复合材料（WPC）是该领域的一种创新解决方案，主要是因为生物膜的有效表面积大。在研究中，聚丙烯（PP）和聚氯乙烯（PVC）被用作基质。还从针叶树中选择了两种类型的商品木粉用于研究：粒径在70 μm–150μm范围内的Lignocel C 120和粒径在0.8–1.1 mm的L9和木片，用于用于生产刨花板的工业规模被用作填充剂。对新形成的生物膜进行了定量和定性分析。

结果

研究表明填料及其粒径对复合材料表面生物膜形成敏感性的直接影响。

结论

聚丙烯PPH 648 T和40％wt。L9型木粉中最易受生物膜形成的影响。纯聚丙烯PPH 648 T是最不易受影响的材料。
