NOVELTY - A heavy sewage purifier includes an electronic flocculation system, integrated heavy sewage purifier and a programmable logic controller (12). The electronic flocculation system comprises an electronic flocculator (1). The cathode and anode are controlled by the programmable logic controller. The electronic flocculator is installed on the water inlet pipe assembly (2). The integrated heavy sewage purifier (13) is installed on the purifier base (11). The rotary floater clarifying pool assembly (4) is installed on the central part of the bottom plate (14).    USE - Heavy sewage purifier for drinking water and water production.    ADVANTAGE - The heavy sewage purifier does not need to consume the medicament dispensing device and construction; has low labor intensity, low cost operation, small floor area, water quality, and clean process; is environment-friendly; and has convenient management and low investment.    DETAILED DESCRIPTION - A heavy sewage purifier comprises an electronic flocculation system, integrated heavy sewage purifier and a programmable logic controller (PLC) (12). The electronic flocculation system comprises an electronic flocculator (1). The cathode and anode are controlled by the PLC controller. The electronic flocculator is installed on the water inlet pipe assembly (2). The integrated heavy sewage purifier (13) is installed on the purifier base (11). The rotary floater clarifying pool assembly (4) is installed on the central part of the bottom plate. The radial hole of the lower part of the cylinder body is connected with a water inlet pipe assembly. A mud discharging pipe is welded on the cylinder body outer water purifier bottom board, and connected with the mud discharging valve which is connected with the PLC controller. A clean assembly and a filter tank assembly are set between the rotary floater clarifying pool assembly and the water purifier body. A backwashing pipe and a backwashing valve are arranged at the top of the filter tank assembly. The backwashing valve is connected with the PLC controller. The inclined bracket is installed on the rotary floater clarifying pool assembly which is welded with the water purifying device main body, paved on the inclined pipe. A head filter plate is installed on the top part of bottom part of the water purifier bottom plate. The head filter plate has a filter head. The filter material is filled between head filter plate and the inclined tube or between the head plate and the clean water tank. The water purifying water outlet pipe of the water purifier is led out from the upper part of the annular clean assembly, and the rotary ladder passage assembly is mounted on one side of the integral heavy sewage purifier.
