NOVELTY - Preparation of a cleaning media comprises preparing a culture solution including distilled water, sodium bicarbonate, and glucose; preparing a strain by mixing Rhodopseudomonas palustris, Lactobacillus acidophilus, Saccharomyces cerevisiae, and Aspergillus cellulosae; preparing a composite bacteria mother solution by performing anaerobic fermentation in a mixture of the strain and the culture solution; mixing dry wood flour with concentrated composite bacteria mother solution; and mixing subtilisin with the wood flour containing composite bacteria.    USE - Method for the preparation of a cleaning media used for dirty and odorous urinal (claimed).    ADVANTAGE - The cleaning media is all-nature environment-friendly, and does not erode the urinal or pipe made of any material.    DETAILED DESCRIPTION - Preparation of a cleaning media comprises preparing a culture solution by adding distilled water to (g) ammonium chloride (0.75), sodium bicarbonate (1), dipotassium phosphate (0.5), sodium acetate (1.75), magnesium chloride (0.4), sodium chloride (2), and glucose (10); preparing a strain by mixing a photosynthetic bacteria preferably R. palustris with a bacterial content of 30x 108/mL, lactic acid bacteria preferably L. acidophilus with a bacterial content of 5x 108/mL, a microzyme preferably S. cerevisiae with a bacterial content of 20x 108/mL, and a filamentous fungus preferably A. cellulosae with bacterial content of 5x 106/mL at a ratio of 60:25:10:5; preparing a composite bacteria mother solution by pouring the strain and the culture solution at a ratio of 1:49 in a fermentation kettle, keeping pH at 4-5 and at 25-30 degrees C, performing anaerobic fermentation for 4-10 days, and indicating that the fermentation is completed when generating fragrant wine aroma with slightly sweet and sour smell; dissolving starch-acrylamide graft copolymer in water to dilute 10 times, preparing 10% solution, and sterilizing; preparing an initial set composite bacteria solution by adding 1-3% graft copolymer solution to the composite bacteria mother solution, and uniformly stirring; dissolving sodium carboxymethylcellulose in water to dilute 10 times, preparing 10% solution, and sterilizing; adding 1-3% sodium carboxymethylcellulose solution to the initial set composite bacteria solution, and uniformly stirring for 10 minutes; preparing 10% concentrated composite bacteria mother solution by generating bacteria flocculate in the bacteria solution, and separating supernatant from concentrated flocculate; mixing dry wood flour with the concentrated composite bacteria mother solution at a ratio of 3:1, and drying until the water ratio is not greater than 15%; and mixing subtilisin with the wood flour containing composite bacteria at a ratio of 8:92, placing in a cotton bag, and placing the bag in a bamboo-weaved small cage.
