TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: In the step (i), the Bacillus subtilis powder is prepared by (a) adding the seed culture medium in a seed tank, and inoculating Bacillus subtilis suspension prepared by a slant strain in the seed tank according to an inoculation amount of 1%, then culturing for 8 hours with a ventilation amount and volume ratio of 1:1.2, and at a speed of 350 rotations/minute at 30 degrees C; (b) adding the fermentation culture medium in a fermentation tank, inoculating a strain culture solution in the seed tank, and feeding for 5 minutes according to the inoculation amount of 10%, then culturing for 8 hours with a ventilation amount and volume ratio of 1:0.4, at a speed of 300 rotations/minute at 30 degrees C, then increasing the ventilation amount and volume ratio to 1:0.6, and culturing for 12 hours, then finally changing the ventilation amount and volume ratio to 1:0.8, and feeding fermentation supplementing solution (5%), supplementing and fermenting for 20 minutes, and culturing for 12-16 hours; and (c) adding the fermented bacterial solution in modified starch (18-25%) and clinoptilolite powder (2-5%), and uniformly stirring and mixing, spray-drying by using a high-speed centrifugal spray-drier, to obtain the product. The fermentation supplementing solution is prepared by uniformly mixing silkworm chrysalis, lime and water according to a weight ratio of 100:6:600, and heating to hydrolyze for 1 hour under 1x 105 pa of steam pressure. In the step (iiib), the original working strain is cultured by (p) adjusting the pH of the culture medium comprising glucose, magnesium sulfate, monopotassium phosphate, calcium carbonate and distilled water to 6.5-7.5; (q) sterilizing for 20 minutes at 121 degrees C, and cooling; (r) adding sewage or sludge to-be-separated occupying 5-10% of the total weight, and culturing for 3-4 days in a ventilated and dark place at 20-30 degrees C till the color of the culture solution changes from colorless to faint yellow; and (s) transferring and culturing thrice to obtain a yellow bacterial solution. In the step (iiib), the original working strain is cultured by adjusting the pH of the culture medium comprising glucose, magnesium sulfate, monopotassium phosphate, calcium carbonate and distilled water, to obtain a pale yellow bacterial solution. In the step (iiib), the original working strain is cultured by adjusting the pH of the culture medium comprising phosphorus powder, monopotassium phosphate, dipotassium phosphate, peptone, sodium chloride, organic phosphorus and distilled water to 6.5-7.5, then adding to-be-separated sewage or sludge occupying 3-5% of the total weight, culturing at 25-30 degrees C till the color of the culture solution changes from colorless to pale yellow, and culturing twice to obtain the pale yellow bacterial solution. The compounding agent culture medium is prepared by mixing the culture medium materials comprising swilling dregs fermented by decayed leaf powder, saw dust, medicinal stone powder, rust powder, probiotic compound bacteria and lactic acid, and the to-be-treated sewage or sludge according to a weight ratio of 1:20-50, then fermenting and filtering.
