description | In order to improve the utilization rate of the surplus sludge, this experiment investigated the efficient hydrolysis of the residual sludge, explored the effect of sludge nitrogen source, analyzed the influence on the content of protein, amino acid, polypeptide and particle size of the sludge hydrolysis index, and the extraction conditions were optimized by response surface analysis. The maximum protein extraction rate of the residual sludge at the reaction pH of 60°C and =7. Here, the particle size of S sludge was gradually reduced, reduced by 1.1% by 500 m-100 um, 7.5% by 30-50 μ m, 5.4% by 10 μ m-30 μ m, and 0-10 μ As m decreases 13% and sludge increased 13% Nt particles become thinner, larger than surface area and more developed pore structure. |
