Problems solved by technology

However, at present, the degree of resource utilization of excess sludge is very limited. One of the important reasons is that the existing treatment equipment cannot effectively increase the protein content in the reactor, resulting in that when the excess sludge is treated by cellulase, the cellulose Low enzyme utilization and high heat inactivation

Abstract

The invention provides an efficient resourceful treatment device for residual sludge. The efficient resourceful treatment device comprises a chemical mixing unit, a liquid-solid separation unit, a liquid-phase concentration unit, a solid-phase grinding unit and a reaction kettle, wherein an outlet of the chemical mixing unit is connected with an inlet of the liquid-solid separation unit; a liquid-phase outlet of the liquid-solid separation unit is connected with an inlet of the liquid-phase concentration unit, and a solid-phase outlet of the liquid-solid separation unit is connected with an inlet of the solid-phase grinding unit; an outlet of the liquid-phase concentration unit and an outlet of the solid-phase grinding unit are both connected with the reaction kettle. According to the device, content of protein in the reaction kettle can be increased, utilization rate of cellulase is increased, heat inactivation rate of cellulase is reduced, and the use amount of cellulase is reduced.

Description

technical field [0001] The invention belongs to the technical field of energy conversion, and relates to a high-efficiency resource treatment device for surplus sludge. Background technique [0002] In recent years, with the acceleration of urbanization, the output of sludge has also risen sharply. According to the survey, based on a water content of 80%, the total sludge output in my country will soon exceed 30 million tons, and by 2020 it will exceed 60 million tons. However, because the final disposal of sludge is faced with the dual choice of safe disposal and resource utilization, the effective disposal of sludge is even more difficult. Especially the excess sludge, which is rich in organic matter (such as protein, lipid and lignocellulose, etc.), the total organic matter can account for 40% to 90% of the dry weight of the sludge, and has a considerable potential for resource utilization. Therefore, it is of great significance to research and develop new waste sludge ...
