denitrification deep bed filter-飞禽走兽游戏机

based on the "upflow filter" technology, the denitrification deep bed filter developed by shenzhen qingquan has the function of removing ss, tp and tn at the same time. the utility model has the advantages of high filtration speed, strong pollutant holding capacity and good denitrification effect, and the water flow moves in the same direction with the nitrogen, so there is no need to set up a special nitrogen driving device. the denitrification filter of most other enterprises is downflow filtration, the surface layer is easy to be blocked, the tn removal amount is small, and the head loss is large.

1. the upstream flow filtration method does not need to consider the nitrogen-

1. the removal value of total nitrogen is high, up to 24mg / l;

2. the carbon source is less than 3-4mg / mgtn, which is more than 30% less than the international famous brand downflow denitrification filter;

3. it has the function of simultaneous nitrogen and phosphorus removal, so it does not need a pre high-efficiency sedimentation tank when the project land is limited;

4. no need to consider nitrogen driving measures, the effluent quality is better, the filtration cycle is long, and the washing water consumption is low;

5. the water to be filtered is completely isolated from the air, without a large amount of heat dissipation process on the surface, greatly reduced by the impact of low temperature, to ensure the removal effect of total nitrogen in low temperature period;

6. mature and advanced carbon source precise dosing control system to ensure that the carbon source is not over fed;

7. the upper part of the filter is clear water, clean and beautiful, with good sensory effect.
