Core filtering technique taking carbon compound composite membrane component 22 as device is realized after oil-containing polymer-bearing waste-water is processed and is reached A1 standard, and keeps filtering the continual and steady of energy.It is a kind of common phenomenon in filtration procedure that film pollutes, and because its meeting that affects on permeate flow and transmembrane pressure produces and has a strong impact on film properties, therefore guarantees in the following manner the cleaning and regeneration of carbon compound composite membrane:
By utilizing the hydrophilic and oleophobic characteristic of carbon compound film assembly 22, prevent the pollution of organic material, utilize the chemical stability of carbon compound composite membrane component 22, can carry out with clean-out systems such as strong acid, highly basic, strong redox agents the cleaning and regeneration ability of assurance device; Utilize the feature that its physical strength is high, under high temperature, high pressure, use and clean the adaptation condition ability of assurance device; Secondly device configuration back pulse producer 25, utilize it to send high frequency " piece " pulse, oppositely pass film from permeate side, obtain enough large reverse TMP(transmembrane pressure that can infilter internal passages), the most important thing is to obtain " piece " pulse in permeate side, then discharged with a quick release mechanism by increasing pressure, the pollution substance on whole film surface is done to become flexible, is discharged with current.
The realization of above function is all by the fully automatic operation of PLC full-automatic control system implement device.
Penetrating fluid enters and produces water tank, stoste enters the recycle system 2 by water inlet system 1, the recycle system by recycle pump 21, magnetic flow meter 210 and carbon compound film assembly 22 and pipeline composition is carried out internal recycling, concentrated solution is discharged by a certain percentage by motor-driven control valve 72 and electronic micrometering valve 73, and motorized valve 71 cuts out in the time that medicament rinses.Backwashing system 4 is by the magnetic flow meter 35 of instrument on-line detecting system, thermometer 3, pressure warning unit 24 detects the recycle system 2 imports, filtrate outlet 29, the flow of concentrated solution outlet 28, pressure, the parameters such as temperature, control housing 8 by the PLC with airborne sensor data recording function, computer shows that the default sequence of control such as operating system are controlled respectively back pulse producer 25 and backwashing system 4 carries out backwash and back pulse by the parameter of setting, back pulse producer 25 sends high frequency " piece " pulse, oppositely pass film from permeate side, thereby keep the high-performance of film without fouling products by keeping film to clean, control backwashing system 4 and carry out water backwash by the parameter of setting, the pickling system of medicament rinse-system 6 carries out pickling, caustic washing system carries out alkali cleaning, control the temperature of acid solution and alkali lye simultaneously.
Filtering process and backwash flow process are automatic operation.Filtration parameter by PLC preinstall apparatus: backwash starts to carry out conventionally in the time of the increase of transmembrane pressure (TMP) or film energy decreases 50%, can select as required transmembrane pressure or film energy settings preferential.Back pulse recoiled by the time of setting, and during water recoil, back pulse quits work.Alkali cleaning and pickling cycle are determined by the sewage quality of actual treatment, in the time that transmembrane pressure after back pulse and water backwash is above from initial value increase by 15%, recommendation chemistry is clear, soda liquid and acid liquor temperature and scavenging period are controlled automatically by PLC, the online detected temperatures of temperature sensor also transfers to PLC, according to the unlatching of preset temp control heater and close.
In industrialized application, this carbon compound composite membrane oil-containing polymer-bearing waste-water advanced treatment apparatus can be arranged on after the filtration unit of existing treatment scheme least significant end, also can be arranged on the arbitrary process section after slurry tank.When difference is to be arranged on existing technique end, the load of film is less, and the backwash and regeneration cycle is longer, and the working cost of device itself is lower.Be arranged on slurry tank segment process afterwards, the load of film is larger, the cycle of backwash and regeneration shortens, the working cost of device own is larger, but if newly-built water technology section,, owing to having replaced traditional multilevel processing technology, engineering overall cost can reduce, the working cost of entirety also can reduce, and management process is also simplified.
