Abstract

The invention discloses a method for treating sludge of a sewage plant by adopting a microbial agent. The method comprises the following steps: digging sludge pits in a production shed; taking the microbial agent, wherein the microbial agent is prepared from bacteria powder A, bacteria powder B, bacteria powder C and accessories; transporting slurry to the production shed, spraying a bacteria powder A solution in two slurry pits, paving the slurry, spraying the bacteria powder A solution, and adding an accessory A solution; then paving the slurry, finally spraying a bacteria powder B solution, culturing at normal temperature, and taking out to obtain original slurry yeast; averagely dividing the original slurry yeast into 16 parts, respectively adding 8 parts in 8 slurry pits, paving the slurry in the 8 slurry pits, spraying a bacteria powder C solution while stirring, then adding an accessory B mixture while stirring, finally paving the slurry, spraying the bacteria powder C solution while stirring, and then adding the accessory B mixture while stirring; covering with a plastic film, and fermenting for 4 to 6 hours at normal temperature to obtain fermented slurry; paving the fermented slurry for carrying out rotary tillage and sun drying, holding the fermented slurry togehter into a big pile, and grinding the fermented slurry into granules, thereby completing treatment.

Description

technical field

[0001] The invention relates to a method for treating sewage plant sludge, in particular to a method for treating sewage plant sludge with microbial agent. Background technique

[0002] Activated sludge method is a commonly used method for sewage treatment, which has the advantages of low investment, simple operation and good treatment effect, but it will produce a large amount of sludge. According to the latest research report, by the end of 2015, the annual output of dewatered sludge in my country will exceed 26 million tons, and the investment in sludge treatment and disposal will reach 60 billion yuan. Finding effective sludge treatment and disposal methods is of great significance to improving the economic, environmental and social benefits of my country's sewage treatment industry.

[0003] Sludge from urban sewage plants has the characteristics of high organic matter content and high hydrophilicity. It is easy to combine with water molecules in differ...
