Example Embodiment
[0022] Example 1
[0023] A fixed water purifying agent, which comprises a compound microbial preparation and an immobilized carrier.
[0024] The composite microbial agent is composed of heterotrophic nitrifying bacteria-Acinetobacter, Candida and Bacillus subtilis.
[0025] The preparation method of the composite microbial inoculum is: cultivating Acinetobacter, Candida, and Bacillus subtilis to a concentration of 1×10 according to a conventional culture method. 7 Bacteria / ml, and then mix according to the volume ratio of 3:1:2 to obtain;
[0026] The Acinetobacter SP. is ATCC NO.17978;
[0027] The Candida is (Candida utilis) ATCC NO.22023;
[0028] The Bacillus subtilis is (Bacillus subtilis) ATCC NO.6633
[0029] The immobilized carrier is composed of ceramsite and zeolite in a weight ratio of 1:1;
[0030] The immobilized carrier and the composite microbial inoculum were mixed according to a volume ratio of 1:6, and cultured for 48 hours under aeration (stirring speed of 120rpm / Min) ...
