Abstract

The invention discloses a sludge treatment system and a working method thereof. The sludge treatment system comprises a raw sludge storage tank, a first spiral conveyor, a sludge thinning and stirringmachine, a sludge filtering and water permeating tank, a second spiral conveyor and a sludge air drying box, wherein the raw sludge storage tank is used for storing raw sludge; the first spiral conveyor is used for conveying the raw sludge at the bottom part of the raw sludge storage tank to the sludge diluting and stirring machine; an impurity recycling box is arranged at the side surface of thesludge filtering and water permeating tank and is communicated with the interior of the sludge filtering and water permeating tank; the sludge filtering and water permeating tank is provided with animpurity pushing mechanism which is used for pushing the filtered impurities into the impurity recycling box; the second spiral conveyor is used for conveying the sludge after sludge filtering and water permeating in the sludge filtering and water permeating tank into the sludge air drying box. The sludge treatment system and the working method have the advantages that the sludge can be systematically filtered and dried by air; the working method is reasonable, and the sludge is thoroughly treated.

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...
