Abstract

The invention aims to provide an electro-osmosis sludge dewatering system. According to the technical scheme, the electro-osmosis sludge dewatering system comprises a feed system, a sludge dewatering system and a discharge system. Sludge with 80% water content which is produced from a sludge treatment plant undergoes caching, and the whole set of feed system with sludge caching equipment is assembled at the front end of electro-osmosis equipment. Thus, utilization rate of sludge which enters the dewatering system can be raised effectively. An electro-osmosis sludge dewaterer is adopted as a sludge dewaterer. According to the electro-osmosis sludge dewaterer, dewatering is realized by the phenomenon that sludge particles and water molecules are separated and move in opposite polarity directions. By an extra direct-current electric field and through sludge high-drying dewatering equipment for removing through a certain mechanical pressure a part of interstitial water and absorbed water which cannot be removed by mechanical filter-press in materials, water content of active excess sludge is reduced below 60%. Dewatered sludge is thin mud cakes which are beneficial to later deep drying and natural airing. Thus, aerobic composting or combustion disposal can be carried out.

Description

technical field [0001] The invention relates to the field of environmental protection mechanical processing, in particular to an electroosmotic sludge dewatering system. Background technique [0002] Excess sludge (abbreviated as sludge) is a kind of solid pollutant produced when urban sewage treatment plants treat sewage. plastid. Most urban sewage treatment plants use activated sludge process to treat sewage. Due to the need for the replacement of microorganisms in activated sludge, excess sludge is inevitably produced in the process of sewage treatment, which is called excess sludge. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. Therefore, sl...
