Embodiment
[0020] Such as figure 1 As shown, Embodiment 1 of the present invention provides a kind of sludge reduction method that adopts microwave and biological enzyme and microorganism to combine, the microwave pretreatment part of this technology sludge, lysozyme reaction tank and microbial anaerobic reduction tank three parts composition. The pretreatment part is the microwave pretreatment tank, the middle is the fully mixed part of lysozyme and sludge, and the third part is to use the complex anaerobic microorganism to decompose its organic matter. The method includes:
[0021] Step 1. In the microwave pretreatment tank, pretreat the sludge with an organic matrix content of more than 45% by microwaves with a frequency of 107.5GHz and a wavelength of 219.7mm for 15min-35min. The pretreated sludge will destroy the microbial cells ;
[0022] Step 2, the mixing mass ratio of lysozyme and microblog pretreated sludge is 1:1500, the temperature in the reaction tank is controlled betwee...
