适于集约化水产养殖的固定化微生物技术的初步研究

采用生物强化技术尝试建立高效、价廉、实用性强的固定化微生物水质处理技术。根据水产养殖特点,选择了网片、波纹板、竹球等不同载体,对有益微生物制剂进行吸附后,比较其对人工模拟养殖废水处理的效果,最终确定竹球为理想的吸附载体材料;研究了最适母液浓度和吸附时间、水体中作用持续时间等;进行了对不同的商业化微生物制剂与单纯芽孢菌的降解效果比较,得到最佳制剂种类和优化的工艺参数。

Preliminary studies on immobilized microbe technics for intensive aquaculture

An effective, cheap and practical method to improve water quality was developed by bioaugmentation and immobilized-microbe. After the microbe was adsorbed by different materials including plastic net, ripple plate and bamboo ball, their degradation effects on artificial aquaculture sewage water were compared and bamboo ball was the ideal material. The optimum microbial preparation concentration and adsorption time as well as the duration in water were also investigated. Thus the suitable microbial preparations and the optimized technologic parameters were obtained.
