The invention discloses an oil removal membrane
system and method. The oil removal membrane
system comprises an oil removal adjusting tank, a
bag filter, a poly
ceramic membrane, a
water production tank and a chemical
backwashing tank. According to the oil removal membrane
system and method, water is produced through the flow of
oily wastewater, the oil removal regulating reservoir, the poly
ceramic membrane, the
water production tank and
water production, so that a plurality of process units are reduced, the operation cost and the equipment
failure rate are reduced, the process flow is short, the debugging period is short, and the debugging time is saved. The
polymer ceramic membrane is adopted and has the characteristic of high
temperature resistance, the temperature of
produced water is 55 DEG C, cooling treatment is not needed, the
heating temperature difference of treated reinjection water is low, energy is saved, and the
energy consumption of the system is reduced. A high-flow-rate filtering design is adopted, the flow rate of
oily wastewater is increased, multiple times of circulating
filtration are achieved, oil stains attached to the surface of an oil removal film are effectively reduced, the water
production rate is kept stable, the
backwashing frequency, especially the chemical
backwashing frequency, is reduced, and the fluid flow loss caused by the influence of a water inlet pump on circulating circulation is effectively reduced by arranging a one-way valve on a bypass.
