黄孢原毛平革菌降解比布列希猩红的水处理反应器的设计和比较

Design and comparison of reactors for dye Biebrich Scarlet water treatment by Phanerochaete chrysosporium

以染料比布列希猩红为降解对象,采用细胞固定化技术,建立6种黄孢原毛平革菌的水处理反应器工作体系。研究表明,海藻酸钙小球-生物流化床、不锈钢网片反应器、以海绵和泡沫为载体的池形反应器（反应器Ⅰ和Ⅱ）及以裹夹生物海绵的钢丝网为载体的池形反应器（反应器Ⅲ和Ⅳ）等不同类型的反应器均具有较好的处理效果;15—16d内,染料脱色降解率可达95％左右。相比较而言,反应器Ⅳ具有操作简单、反应启动快、处理水量大和节能低耗等优点。

6 types of reactors for water treatment were established by Phanerochaete chrysosporium with Biebrich Scarlet as a substrate and cell immobilization. The study showed: calcium alginate beads-biological fluidized bed, steel net disc reactor, tank-model reactors using sponge cubes and foam cubes as supports (Reactor Ⅰand Reactor Ⅱ), reactors containing complex supports with steel net and sponge (Reactor Ⅲ and Reactor Ⅳ), all had good results of treatment, the efficiencies of dye removal was up to about 95% in 15-16 d. Comparatively, Reactor Ⅳ had such advantages as simple operation, rapid initiation, more volumes of water to be treated and effective cost.
