ADVANTAGE - The system: makes use of high quality active filter material and occupies less area; has high purification rate and efficiency, and automatically controllable electric apparatus.    DETAILED DESCRIPTION - Purifying system of stone sewage comprises three main parts of a comprehensive processor, a sludge collector, a separation purifier and corresponding pipeline, valve and electric control elements. The comprehensive processor is provided with a sewage suction pump, an electric contact pressure gauge, a water level switch, an electric control apparatus, a medicine storage tank, a stirrer and a mixer. The sludge collector is provided with a collecting chamber, a sludge-water separator, an exhaust valve and an electric drain valve. The separation purifier is provided with a check port, an exhaust valve, an active mineral sand filter, a water distributor and five electric valves. The medicine mixer is arranged in the comprehensive processor. The mixer is provided with multiple water path distribution switches arranged in the water pipeline. The water level switch is floating ball type. The sewage suction pump is connected to the pipeline of the medicine liquid mixer. A guide tube is arranged in the medicine storage tank. The guide tube is connected with the mixer. The high precision filter of the sludge water separator in the sludge collector is acid-alkali resistant material. An active mineral sand filter layer is arranged in the separation purifier, and the active mineral sand filter layer is active zeolite and quartz sand.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the purifying system of stone sewage.
