NOVELTY - Preparation of municipal sludge vegetable matrix comprises adding acetic acid and rotten citrus into municipal sludge, ultrasonic treating at 20 kHz for 25 minutes, air-drying to obtain matrix I, heating matrix I in oven to 60-65 degrees C, crushing, screening using mesh with 1-2 mm pore size, mixing matrix I and corn straw to obtain matrix II, adding water, mixing matrix II and microbial fermentation agent at 30 degrees C to obtain matrix III, fermenting matrix III at room temperature for 25 days to obtain matrix IV, crushing, and mixing matrix IV with adjuvant to obtain municipal sludge vegetable matrix.    USE - Method for preparing of municipal sludge vegetable matrix (claimed).    ADVANTAGE - The method reduces environmental pollution.    DETAILED DESCRIPTION - Preparation of municipal sludge vegetable matrix comprises adding 32 g of 0.7 mol/L acetic acid and 34 g rotten citrus per liter of municipal sludge, ultrasonic treating at 20 kHz for 25 minutes, air-drying to obtain matrix I, heating matrix I in oven to 60-65 degrees C, crushing, screening using mesh with 1-2 mm pore size, mixing matrix I and corn straw at mass ratio of 4:1 to obtain matrix II, adding 68-72 wt.% water, mixing matrix II and microbial fermentation agent at feed ratio of 5 m3:1 kg at 30 degrees C to obtain matrix III, fermenting matrix III at room temperature for 25 days to obtain matrix IV, crushing, and mixing matrix IV with adjuvant to obtain municipal sludge vegetable matrix. The microbial fermentation agent comprises 20-25 pts. wt. soybean extract, 1-2 pts. wt. Bacillus subtilis, 3-4 pts. wt. silicate bacteria, 2-4 pts. wt. Trichoderma viride, 8-12 pts. wt. Lactococcus lactis, 2-4 pts. wt. Actinomyces, 1-2 pts. wt. Bacillus mucilaginosus, 2 pts. wt. rice Flavobacterium, 3-6 pts. wt. yeast, 10-13 pts. wt. Azotobacter chroococcum, 8-12 pts. wt. cellulase, 8-12 pts. wt. protease and 5-6 pts. wt. phosphorylase. The adjuvant comprises 10-20 pts. wt. mast, 10-12 pts. wt. Cnidium monnieri, 30-40 pts. wt. peony root, 15-18 pts. wt. camphor tree bark, 3-4 pts. wt. laurocapram oxadiazon and 900-1000 pts. wt. water.
