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...

Abstract

The invention provides a sludge decrement method by combining microwaves, biological enzyme and microorganisms. The method comprises the steps that sludge of which the content of an organic medium is45% or above is pretreated for 15-35 min in a microwave pretreatment tank; the mixing mass ratio of lysozyme to the sludge after microwave pretreatment is 1:1,500, and a mixed solution of lysozyme andthe sludge is obtained in a reaction tank; after the mixed solution of lysozyme and the sludge is mixed with composite bacterial strains, the organic medium in the sludge is decomposed, available energy is generated, the sludge amount is decreased, and the composite bacterial strains are peptostreptococcus, veillonella, propionibacteria, fire source methanococcus lactobacillus, methanosarcina barkeri, extreme thermophilic archaea and anaerobic ammonium oxidation bacteria. According to the sludge decrement method, the microwaves, special-effect enzyme and microorganisms are adopted for completely decreasing the amount of organic medium sludge generated by a biochemical system, and the sludge is converted into the available energy through a technology; the method has the ideal decrement effect on biochemical sludge generated in the process of treating municipal wastewater and industrial wastewater.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge weight reduction method combining microwaves, biological enzymes and microorganisms. Background technique [0002] In general, a sewage treatment plant can produce 5-8 tons of sludge with a moisture content of 80% for 10,000 tons of domestic sewage, and 10-30 tons of sludge for 10,000 tons of industrial sewage. Calculated according to the unit output of 7 tons and 20 tons, respectively, in 2020, the amount of urban domestic sludge generated in my country will be 43.82 million tons, and the amount of industrial sludge generated will be 40 million tons, totaling 83.82 million tons. Contrary to the continuous increasing trend of sludge production, the harmless chemical rate of sludge in my country is still low, and a large number of sewage plants use direct dumping or simple landfill disposal methods to treat sludge. According to data from the E20 Research Institut...
