Example Embodiment
[0029] Example 1:
[0030] 1. Collection of sludge: sludge produced by urban sewage treatment plants with a water content of 75-85% is used as raw material.
[0031] 2. Collect fresh, non-deteriorating filter mud from the sugar factory as raw materials.
[0032] 3. Collection of strains: collect the Hongshengyuan brand microbial fermentation inoculum produced by Guangxi Hongshengyuan Environmental Protection Technology Co., Ltd. as strains, and expand the strains into a stock solution with no less than 100 million viable bacteria / ml. In addition, the pH of the stock solution of the strain is not less than 6.5, the color is a translucent yellow-brown liquid, and the smell is relatively sour.
[0033] The specific implementation is as follows:
[0034] (1) The ratio of raw materials: sludge 59.9%, sugar factory filter sludge 40%, biological strain 0.1%;
[0035] (2) Fermentation: premix the above-mentioned sludge and sugar factory filter sludge, then add biological strains to mix and stir...
