Electrodialysis oxidation method diaphragm sheet frame sludge dewatering machine

Abstract

The invention discloses an electrodialysis oxidation method diaphragm sheet frame sludge dewatering machine which comprises a sludge dewatering machine, wherein the sludge dewatering machine comprises a main rack, a plurality of filtering plates, an electric control box, a sludge inlet, an extruded water tube, a hydraulic device, a hydraulic rod and a water outlet, wherein the plurality of filtering plates are arranged in parallel on the main rack; the outer surfaces of the filtering plates are covered with filtering cloth; the filtering plates are provided with drainage holes, rare earth metal pieces, direct flow guide lines, side filtering plate diaphragm pieces, metal electrode plates and extruded water backflow holes. According to the sludge dewatering machine, due to the adoption of an electric dewatering technique, cell water in sludge can be extracted, and the sludge dewatering effect of a high dry diaphragm sheet frame machine is improved.

Description

technical field [0001] The invention belongs to the field of sludge treatment, and in particular relates to a deep sludge dehydrator. Background technique [0002] Treatment and reuse of excess sludge from sewage treatment plants is a very important issue. At present, the commonly used sludge treatment technologies in the world are land use, landfill and incineration, etc. Due to the shortage of land resources and other environmental pollution problems, especially in large cities, the proportion of sludge land use and landfill is gradually decreasing, while incineration The proportion has increased, and it has gradually become one of the main sludge disposal methods in developed countries. The remaining sludge of domestic urban domestic sewage plants has high moisture content, high sand content, and low calorific value, resulting in low incineration efficiency, large corrosion to incinerators, and low calorific value utilization. The dehydrated sludge can bring a lot of co...

AI Technical Summary

Problems solved by technology

For ordinary mechanical dehydration, the water content after mechanical dehydration is 80% to 85%. Due to the high water content, the transportation and treatment of sludge are expensive

In recent years, mechanical dehydration of high-dry diaphragm plate and frame can reduce the moisture content of sludge to below 60%, but it needs to add a large amount of lime and other chemicals, which is not conducive to subsequent treatment
