Pre-treatment equipment for raw water purification such as waste water and ground water

摘要

The pretreatment device for purification of raw water, such as wastewater and groundwater, which improves the life-span economical efficiency of the apparatus by filtrating and dehydrating the initial raw water prior to supply to the raw water treatment and groundwater purification system, The structure of the back pressure water filter 2 is a structure in which the base water is sent from the reservoir 1 to the raw water treatment device via the reverse water pressure filter 2 and the dehydrator 3, A water outlet pipe 8a on the side of the treatment plant side of the raw water supply conduit 7a and a drain pipe 8a on the side of the dehydrator 3 and a reverse water pressure pipe 8a on the dehydrator 3 side are connected to the upper end of the heater assembly 7, The structure of the dehydrator 3 is a structure of a centrifugal separator 11 that is rotated by a motor and a raw water inflow pipe 12 from the heater 2 is piped and the outflow pipe (13), and a transmission mechanism (14) And a sludge discharging opening (17) for receiving the pressure of the compressor is formed at the center of the shaft. The sludge discharging port (16) Pretreatment device
