A sludge treatment system and its working method

Abstract

The invention discloses a sludge treatment system and a working method thereof, comprising an original sludge storage tank, a first screw conveyor, a sludge dilution mixer, a sludge filtration seepage pool, a second screw conveyor and a sludge air-drying box, The original sludge storage tank is used to store the original sludge, the first screw conveyor can transport the original sludge at the bottom of the original sludge storage tank to the sludge dilution mixer, and the side of the sludge filtration seepage tank is set There is an impurity recovery box connected to the inside. The sludge filtration seepage tank has an impurity pushing mechanism that can push the filtered impurities into the impurity recovery box. The second screw conveyor can filter the sludge into the seepage tank through filtration and water seepage The final sludge is transported to the sludge drying box. The sludge treatment system and its working method provided by the invention can systematically filter and air-dry the sludge, the working method is reasonable, and the sludge treatment is more thorough.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge treatment system and a working method thereof. Background technique [0002] Sludge treatment is a pollution-free process of thickening, regulating, dehydrating, stabilizing, drying or incinerating sludge. However, current devices or systems for sludge treatment have the following disadvantages: [0003] 1. Without diluting and stirring the sludge, the collected raw sludge is uneven in softness and hardness, which will easily affect the subsequent sludge treatment; [0004] 2. There is no impurity filtering function or the filtering is not thorough. The river sludge contains impurities such as weeds and solid particles, which need to be filtered out one by one; [0005] 3. Sludge drying generally adopts self-evaporation facilities such as sludge drying field (bed), but its drying efficiency is low, or it uses steam, flue gas, hot oil heat source dr...
