Embodiment 1
[0044] This embodiment provides a method for enhancing sludge dewatering performance, which specifically includes the following steps:
[0045] Adjusting the pH value: Weighing the wet sludge, adjusting the pH value of the wet sludge to 6.5; wherein, the specific steps for adjusting the pH value of the wet sludge are, first, using a pH meter to measure the pH value of the wet sludge; secondly According to the measurement results, add 0.1 mL of weak base with a concentration of 0.1 mol / L to the wet sludge. After stirring evenly, measure the pH value of the wet sludge. When the pH value of the wet sludge is 6.5, stop adding Weak base;
[0046] Enzyme pretreatment: first add 4g lysozyme to the wet sludge after pH adjustment, stir evenly, then shake and react at a temperature of 25°C and an oscillation frequency of 155rpm for 2h, then add 1g protease, stir evenly, Shake and react at 45°C and 155rpm for 2 hours. After the reaction is completed, the sludge specific resistance of th...
