(1) Design geometric configuration according to fluid mechanics and strengthen surface adhesion
The outer membrane of the filler is fast renewed and active, the inner membrane is fully protected, and the growth of microorganisms is in good condition. The traditional way of external growth of the filler is changed to make the degradation efficiency of microorganisms higher.
The special structure allows air bubbles and pollutants in the water to freely pass through the inside of the filler, increasing the probability of contact between biofilm and oxygen pollutants, greatly improving the mass transfer efficiency of the system, and improving the biological degradation activity.
The internal biological flora of the packing has a long life cycle and abundant bacterial species, which is particularly suitable for the growth of nitrifying bacteria, and has the characteristics of anaerobic and aerobic, and the effect of nitrification and denitrification is obvious.
(2) The filler has a large specific surface area and more attached biomass
A sufficiently large carrier surface area is suitable for the adsorption and growth of microorganisms, with high effective biological concentration and strong processing capacity.
The higher biological concentration enables the fluctuation of the incoming water quality to be fully dispersed and quickly reduced, thereby improving the impact load resistance of the system.
The scientific formula makes it easier for microorganisms to attach to the filler, so that the microorganisms that are difficult to degrade and easy to degrade organic matter grow together, and the organisms are rich, which improves the treatment effect of the hardly degradable organic matter.
(3) No need for brackets, easy fluidization, and energy saving
Appropriate specific gravity (0.97~0.98 before filming and ~1 after filming), so that the filler becomes floating when the air is stopped, and the aeration is in the suspended fluidized state, which greatly reduces the energy consumption.
The filler rotates freely and smoothly, increasing the impact and cutting of bubbles in the water, breaking large bubbles, extending the residence time in the water, and increasing the utilization rate of oxygen by more than 10%, which effectively reduces the energy consumption for pulling.
(4) Save land, improve processing capacity and effect by increasing filling rate, no need to add new structures
The active biological filler biofilm process only needs to increase the filler dosage on the basis of the original pond to meet the needs of increasing the water load or improving the water quality of the effluent. There is no need to add a new treatment tank, which can save 1/2 to 3/4 of the area.
