Abstract

The invention discloses a continuous electroosmosis sludge drying device which comprises a sludge storage hopper, a water storage tank, a sludge water inlet pipe, a positive electrode mechanism, a negative electrode mechanism, an insulation base plate, a pressure plug cap mechanism and a dry sludge discharge mechanism. The continuous electroosmosis sludge drying device has the advantages that direct currents can be applied to sewage by the positive electrode mechanism and the negative electrode mechanism, sludge particles, with certain applied direct-current voltages, of the sludge and water molecules are separated and shifted towards opposite polar directions, the sludge can be dewatered, and dewatering effects can be adjusted according to the intensity of the applied currents; 'free water' and 'bound water' (cell water) in the sludge can be simultaneously separated from the sludge, and accordingly the sludge can be efficiently dewatered; the 'bound water', which is difficult to be separated, in the sludge can be thoroughly separated from the sludge by means of electroosmosis, and accordingly the dryness of dewatered sludge can be greatly improved; the temperature of the sludge can be increased in dewatering procedures, bacteria which adapt to low-temperature environments can be killed, and accordingly residual medium-high temperature bacterium sterilization effects required by composting treatment can be realized.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a continuous electroosmotic sludge drying device. Background technique [0002] A solid pollutant will be produced when the sewage treatment plant treats sewage. The treated sewage contains an extremely complex heterogeneous body composed of organic matter, inorganic salts, microorganisms and parasite eggs. 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, and it is difficult to se...
