Sludge magnetization dehydration treatment device

Abstract

The invention relates to a sludge magnetization dehydration treatment device and belongs to the technical field of environmental geotechnics. The magnetization dehydration treatment device consists of a bracket, a magnetic action device, a telescopic heating type charging device, a pipeline, a hopper, a reagent sprayer, a sensor, an outer circulation thermostatic water bath, a capillary suction time tester and a sludge collector, wherein the telescopic heating type charging device and the magnetic action device with a variable distance can test the sludge dehydration performance according to different magnetic field intensity gradients; according to the outer circulation thermostatic water bath, uniform heating of the sludge can be guaranteed, and the temperature control precision is high; the sensor and the reagent sprayer are connected with a control operating system, so that the data can be monitored in real time, the reagent delivery is automatically controlled, and the working efficiency can be improved. The device is reasonable in design, simple in structure and convenient to manufacture, the optimal combined parameters of sludge dehydration can be determined under multi-factor cooperative control conditions, secondary pollution is avoided in the sludge dehydration conditioning process, and the device is easy to operate, low in energy consumption and low in cost.

Description

technical field [0001] The invention relates to a sludge magnetization dehydration treatment device, which belongs to the technical field of environmental geotechnical engineering. Background technique [0002] Sludge is a muddy substance with organic matter as the main component formed in the process of sewage treatment. It is a hydrophilic substance with a colloidal structure that is easy to rot and smell, with fine particles, low density, high water content but not easy to dehydrate. Sludge is dubbed an "environmental killer" because of its high water content, high organic matter content, high heavy metal content, and high germ content. Many countries in the world regard sludge as "dangerous goods." [0003] According to incomplete statistics, my country produces more than 30 million tons of wet sludge with a water content of 80% every year, and it is increasing at a rate of about 10% year by year. For a long time, from design to operation of my country's sewage treatmen...
