Since the ceramic filter which is firstly developed in China in the last 90 years is applied and produced, the solid-liquid separation equipment which is designed by the capillary effect principle of micro-pore water permeability and air impermeability is applied to the equipment, and the equipment is widely used by mine enterprises with the advantages of obvious energy saving, high yield, low filter cake moisture, super group recovery rate and the like, and the application industry and field are continuously expanded at present. After the ceramic plate of the ceramic filter is subjected to working time for a certain time (generally after 8 hours), the filtration efficiency is reduced due to the gradual blockage of the micropores of the ceramic plate, and in order to ensure the smoothness and the high filtration efficiency of the micropores of the ceramic plate, the physical back flushing system and the combined cleaning of shutdown ultrasonic oscillation and acid washing are adopted in the starting-up process. The cleaning solution is prepared from pure water and 68% concentrated nitric acid, and is 1-3% diluted nitric acid cleaning solution, which is used for cleaning the blockage which cannot be removed in the back washing process, and the purpose of cleaning is achieved through corrosion of the blockage by the nitric acid, ultrasonic vibration and clean water washing. Nitric acid is a strong oxidizing and corrosive monobasic inorganic strong acid dangerous chemical, and nitric acid solution and nitric acid steam have strong stimulation and corrosion effects on skin and mucosa, and can cause acute poisoning and chemical burn when inhaled or contacted, and the leakage can seriously corrode industrial structures and destroy the environment.
