(4), filter method:

Conventional filtration:

1., pending former water is promoted by pump or enters in steel casing through pipeline self, is power in the differential water pressures of pond body and water leg, former water enters disc filter cloth inside by the filtering surface of filter disc; And after disc filter plate bottom effluent pipe mouth enters water outlet transverse tube overflow to water leg clear water zone; Discharge from delivery port through downflow weir;

2., former water is through filtration in the process of disc inside, the suspension in water is filtered the fibrage interception of face, solid suspension part is trapped within on fibrage, the larger suspension of part drops on body bottom, pond;

3. the suspended contamination, being trapped is constantly gathered on filter cloth, the filtering velocity of filtering surface starts to reduce, in pond, liquid level rises to setting value, purging system starts automatically, backwash assembly drives scavenge pipe to move left and right, under the help of scavenging pump, scavenge pipe siphons away the suspended contamination being trapped on filtering surface as the entrance of dust catcher, thereby reaches cleaning object;

4. the suspended contamination after cleaning is discharged from waste water pipeline together in company with waste water;

Dephosphorization, heavy metal filter:

1., under conventional filtration mode, add corresponding appropriate precipitating medicament in mixing pit or pipe-line mixer after second pond, precipitating medicament is mixed with soluble phosphate class in sewage, thereby form bulky grain sediment, by pump or pipeline, former water is entered to disk type microstrainer again and filter, reach phosphor-removing effect, generally, under the cooperation of early stage biological phosphate-eliminating and interpolation flocculant, water outlet TP can reach 0.2mg/l;

2., under conventional filtration mode, add corresponding appropriate alkaline matter, in mixing pit or pipe-line mixer after second pond, precipitating medicament is mixed with soluble phosphate class in sewage, thereby form bulky grain sediment, by pump or pipeline, former water is entered to disk type microstrainer again and filter, reach removal heavy metal effect.

Disk type micro-filter operation logic:

1. former water enters pond body, and former water enters disc filter cloth inside by the filtering surface of filter disc. And enter clear water zone through disc filter plate bottom delivery port.

2. former water is through filtering in the process of disc inside, and the suspension in water is filtered the fibrage interception of face. Solid suspension part is stayed on fibrage, and the larger suspension of part drops on body bottom, pond.

3. the suspended contamination being trapped is constantly gathered on filtering surface. The filtering velocity of filtering surface starts to reduce, and in pond, liquid level rises to setting value, and purging system starts automatically. Back washing device drives scavenge pipe to move left and right, and under the help of scavenging pump, scavenge pipe siphons away the suspended contamination being trapped on filtering surface as the entrance of dust catcher, thereby reaches cleaning object.

4. the suspended contamination after cleaning is discharged from waste water pipeline together in company with waste water.

Move required condition and start main points:

1. control cabinet is installed and must be had good earth, and earth resistance should not be greater than 4 Ω.

2. the safeguard protection warning system that ensures the design of this equipment connects good; in the time of equipment generation operation troubles; control cabinet sends warning buzzerphone, and alarm lamp and top red alarm lamp light, and automatically cuts off host power supply with protection equipment and other related facilities simultaneously.

3. in the time that filter moves, resistance is greater than the fracture of equipment amount when load torsional pin, this equipment of filter inspection out of service whether stuck with protection equipment.

4. the forward and reverse operation of equipment is protected by stopping means.

5. filter water level reaches ordinary water level, automatically starts filter.

Filter is deposited in water completely, because hydraulic pressure formed a water inlet exiting water process by filter plate to effluent trough. In the time that water flow does not reach designing requirement, illustrate that filter plate needs to clean. Filter cloth adopts special polyester fiber filter cloth, and filtering accuracy can reach 5 μ m.

Filter plate clean: intake pump open, after filter box-body fills water, reducing motor and go out water pump open clean filter cloth, in the time that delivery port flow reaches designing requirement, illustrate that filter cloth cleans up.

Its traffic direction of scavenge pipe is by the control of rear left right limit switch, breaks down while maybe needing to keep in repair when purging system control, plays position limitation protection control action by left and right limit switch.

In sum, the utlity model has is following characteristics:

Products characteristics:

1. filter precision is high: can reach more than 95% the clearance of suspension in water, the impurity such as larger molecular organics, virus, bacterium, colloid, iron are had to certain removal effect, through the processed water of good coagulating treatment, while intaking as 10NUT, below water outlet 5NTU;

2. speed is fast: being generally 5m/h, reaching as high as 10m/h, is the more than 2 times of normal sands filter;

3. pollutant holding capability is large: being generally 15～35kg/m3, is the more than 4 times of normal sands filter;

4. water consumption rate is low: backwash water consumption is less than 1～2% of cycle drainage amount;

5. chemical feeding quantity is low, and operating cost is low: due to filter bed structure and filtrate self, flocculant dosage is 1/2～1/3 of routine techniques. The raising of cycle aquifer yield, ton water running expense also reduces thereupon;

6. floor space is little: produce the identical water yield, floor space is below 1/3 of normal sands filter;

7. because this filter filtering surface sinks to below liquid level completely, filter area reaches 100% utilization rate, and occupation area of equipment is dwindled.

8. cleaning performance is good, has improved the service efficiency of filtering surface, and its Clean after every time is long, makes waste water rate be reduced to 1～3% left and right.

9. filtering surface adopts special polyester fiber filter cloth, and filtering accuracy can reach 5 μ m.

The utility model provides disk type micro-filter, and compact conformation degree is high, and result of use is outstanding.
