Technical parameters

(1) The length-width ratio should be 4-5;

(2) The ratio of length to effective water depth is generally 8-12;

(3) The longitudinal slope at the bottom of the pool is generally 0.01-0.02, and not less than 0.005 when mechanical mud scraping;

(4) The maximum horizontal flow rate of the primary sedimentation tank is 7mm/s, and the secondary sedimentation tank is 5mm/s;

(5) Position of baffle at the entrance and exit:

A. Higher than the water surface of the pool by 0.1-0.15m;

B. Submergence depth of inlet baffle is generally 0.5-1.0m;

C. The submerged depth of exit baffle is generally 0.3-0.4m;

D. The baffle is 0.5-1.0m away from the water inlet and 0.25-0.5m away from the water outlet.

(6) When non-mechanical mud scraping, the buffer layer height is 0.5m. When mechanical mud scraping, the upper edge of the buffer layer should be 0.3m higher than the mud scraping board.

(7) The moving speed of the mud scraper is generally 0.6-0.9m/min;

(8) The diameter of the mud discharge pipe is > 200mm;

(9) The total opening area of the inlet rectifying wall is 6%-20% of the water crossing section;

(10) The outlet serrated triangular weir should be located at 1/2 of the tooth height.

Range of application

Inclined-tube precipitator can not only be used as the supporting equipment of water process such as air flotation method and uplift method, but also can single-stage treatment of a variety of sewage, for example.

1, electroplating wastewater containing a variety of metal ions in the mixed wastewater, copper, iron, zinc, nickel and other removal rates are more than 90%, general electroplating wastewater after treatment can meet the discharge standards.

2, coal mine, mineral processing wastewater can make turbidity in 500-1500 mg/rise to 5 mg/liter.

3, printing and dyeing, dyeing and bleaching wastewater color removal rate of 70-90%, COD removal of 50-70%.
