Abstract

The invention discloses sludge and lime mixing stabilization equipment, which comprises a bin. A feeding hole is formed on the upper part of the bin; a sludge discharge hole and a rotary bottom plate on the bottom are arranged on the lower part of the bin; the lateral surface of the bin is provided with a safety handle and an operating rocker; the safety handle controls the movement of the operating rocker; the operating rocker is connected with the rotary bottom plate on the bottom; and the other side of the bin is provided with a vibration cylinder. In the using process, a sludge and lime mixing material is fed through the feeding hole, and is subjected to heat preservation for 2 hours; the safety handle is opened, the operating rocker is pulled and the rotary bottom plate on the bottomis opened; simultaneously, the vibration cylinder is opened to assist discharging the material, and the sludge is discharged through the discharge hole. Through the equipment, the sludge and the limeare efficiently mixed and then undergo further temperature rise reaction to achieve good sludge stabilizing effect.

Description

technical field [0001] The invention belongs to sludge treatment equipment, in particular to a sludge and lime mixing stabilization equipment. Background technique [0002] The treatment and disposal of urban sewage sludge is accompanied by the generation of sewage treatment plants. Sludge is the largest by-product produced in the process of urban sewage treatment. It has a high moisture content and is not easy to dehydrate. Sludge contains not only perishable organic substances and inorganic nutrients, but also a large number of pathogenic bacteria, parasites or eggs, as well as heavy metals such as Cu, Zn, Cr and Hg, and some harmful refractory organic substances, such as polycyclic aromatic group of hydrocarbons, etc. These chemicals not only contaminate surface water and groundwater sources, but also pollute the air with odor from sludge, and pathogens are a potential threat to human health. In recent years, sludge alkaline enhanced drying technology has attracted mor...
