Immobilized filler, preparation method thereof as well as photosynthetic bacterium-protozoa sewage treatment device and method based on filler

The invention discloses an immobilized filler, a preparation method thereof as well as a photosynthetic bacterium-protozoa sewage treatment device and method based on the filler, and belongs to the technical field of wastewater treatment. According to the immobilized filler disclosed by the invention, a starch filling and amylase etching method is adopted, so that the immobilized filler has certain mechanical strength and a substance exchange function, the internal pore diameter is large enough, a good planting space is provided for protozoa, and the protozoa can be massively propagated. According to the sewage treatment method, protozoa can prey and digest a large amount of excess sludge in the treatment area, the yield of the excess sludge in the treatment area is reduced, and the solid waste output is reduced. 本发明公开了一种固定化填料及其制备方法及基于该填料光合细菌-原生动物污水处理装置及方法，属于废水处理技术领域；本发明的固定化填料通过采用淀粉填充及淀粉酶刻蚀的方法，确保固定化材料具有一定的机械强度和物质交换功能，且内部孔径足够大，为原生动物提供了良好的定植空间，可大量繁殖；本发明的污水处理方法使得原生动物可捕食消化处理区内的大量剩余污泥，降低处理区中剩余污泥的产量，降低固废产生量。
