As shown in Figures 2 and 3, when waste water with suitable flow velocity, as 1 meter per second-3 meter per second, enter outer be with three or three above one pole magnet rings 12, inwall is coated with the nano-catalytic agent film, when two ends have the hollow metal magnetic conduction water pipe 11 of flange 13, can produce 4000 to 20000 Gausses' strong magnetic field in the water pipe, the catalyst film that is coated with in the magnetic line of force that takes place by strong magnetic area and the pipe carries out the magnetic line of force electrochemical reaction, the catalyzer major ingredient is nano titanium oxide and nanometer iron powder composition, electron absorption hertzian wave in catalyst film forbidden band under the magnetic line of force effect (valence associating) and being excited on the conduction band (conduction), promptly on conduction band, produce and have very strong electronegative high reactivity electronics, on the forbidden band, produce the hole (h+) of positively charged simultaneously, very strong active electronics--the hole is right thereby generation has, in magnetic conduction water pipe 11, form redox system, these electronics--hole is to after moving to the catalyst film surface, with dissolved oxygen and H
2O has an effect, final hydroxyl radical free radical (.OH) and the super-oxide ion (superoxide ion) that produce with highly chemical oxidation activity, and hydroxyl radical free radical (.OH) is a strong oxidizer, can be CO with the organism permineralization usually
2And H
2O, the effect of playing sterilization, algae removal and removing portion C OD, BOD, SS.When water passes through magnetic field with certain flow velocity under external force, make cutting magnetic line movement, can produce electric charge and the electromotive force that makes charge movement in the water, so water has just produced physical changes such as electric current, potential difference, so produced into electric energy.At this moment electric charge, current potential have been arranged in the water, the state and the character that will change water itself and be included in other material in the water, this magnetized water has just had tube wall contacted with it, wall of container to produce the energy of physical change and electrochemical change.Be dissolved with the impurity of compositions such as salt, alkali, acid in the water, make water that certain potential of hydrogen be arranged, undissolved solid impurity and micro-metal, non-metallic element are to some extent also suspending simultaneously, these impurity and other element impel has the nonisulated material of certain conductivity to be magnetized, and foreign material such as calcium in the water and iron also can produce the ion of positively charged and negative electricity simultaneously.Ion is owing to plus-minus electric relation attracts each other, make the suspending sundries cohesion and the volume increase, after forming coagulation effect, flow through the then primary filter layer 21 of strainer 2, gac 212 adopts the compound charcoal of photocatalyst potter's clay efficiently in the primary filter layer 21, the photoelectrochemistry adsorptive power is very high, most of suspending sundries tentatively can be filtered, finer foreign material are with living current again toward the upper reaches, hold back through the filter bag 221 of fine filtering layer 22 again, dirt accumulates in the fine filtering bag 221, when reaching a certain amount of, make filter bag 221 internal pressures and bag external pressure form pressure difference, as shown in Figure 3 and Figure 4, when pressure reduction reaches a certain preset value (as 0.5kg/cm2), differential pressure pickup 232 in the control device 23 reaches Mgs 231 with signal, make it open backwashing intake valve 223 and wash water valve 213, via the water feeding pressure of backwashing intake valve 223 from top to bottom, the dirt that filter bag 221 inner faces are produced cleans up, discharge by wash water valve 213, simultaneously, differential pressure pickup 232 triggers and starts recoil counter 233, when 233 timing of recoil counter reach preset value, promptly after filter bag 221 is rinsed totally, recoil counter 233 sends shutdown signal to Mgs 231, Mgs 231 is closed backwashing intake valve 223 and wash water valve 213, equipment among the present invention automatically restores to full filter state again, like this, just by monitoring to filter bag 221 external and internal pressure differences, reflection filter bag 221 object-catching degree, when filter bag 221 external and internal pressure differences to a certain degree the time, foreign material to filter bag 221 inner faces clean automatically, discharging, by constantly so moving in circles, realize automatic self-cleaning filter 2, in this automatic control process, alarm follower 234 carries out corresponding prompting according to differential pressure pickup 232 or the signal that sends of recoil counter 233, report to the police, as shown in Figure 4, make use of the present invention, control process is more directly perceived, if system produces flase operation, can in time solve fault by manual intervention by reporting to the police.In the present invention, Mgs 231 also can be controlled water intaking valve 211 and outlet valve 222 simultaneously, and its control process is similar substantially to the above, need not give unnecessary details herein.
In the present invention, fine filtering layer 22 in the strainer 2 can adopt many group filter bags 221, can dispose corresponding backwashing intake valve 223 and control device 23 as required, its structure, principle and working process repeat no more to basic identical or similar described in the embodiment 2 herein.
