AI Technical Summary
Technical Problem
In sludge hydrolysis treatment, hydrolytic enzymes are easily captured by complex organic matter in the sludge, resulting in low hydrolysis efficiency and difficulty in effectively promoting the resource utilization of sludge.
Method used
A combination of 3,4-bis(dodecyloxybenzylamine) (DDOBA) and a hydrolytic enzyme, preferably lysozyme, cellulase, amylase, papain, or alkaline protease, is used to promote sludge hydrolysis and cell breakdown, thereby improving the duration and efficacy of the enzyme.
Benefits of technology
It significantly improves sludge hydrolysis efficiency, increases COD content in hydrolysate, provides a highly efficient and usable carbon source, enhances nitrogen and phosphorus removal in the biochemical process, and reduces water treatment costs.

Abstract
The application discloses a kind of composition and its application in sludge hydrolysis treatment.The application is by 3,4-didodecyloxybenzylamine (DDOBA) and lysozyme etc.Usually used in sludge hydrolysis treatment enzyme complex, using the obtained composition treatment concentrated sludge finds, DDOBA and enzyme combination use such as lysozyme can significantly improve the hydrolysis treatment efficiency of sludge, significantly improve the COD content in the hydrolysis liquid of raw sludge obtained by treatment.I.e.the composition can effectively promote raw sludge hydrolysis, and insoluble material in sludge, such as polysaccharide etc.is hydrolyzed into soluble small molecule material, to recover more available carbon source from sludge.The recovered carbon source can be reused in biochemical tank, effectively promote the denitrification reaction in biochemical process, make sewage fully denitrification, improve effluent quality while reducing the use of commercial carbon source.The application is beneficial to the resource treatment of sludge, and reduces the operation cost of subsequent water treatment.
