The ZL complex fiber tubular aeration is Tianjin big east micro filters the running water biological treatment equipment which the technical limited company develops. This kind of new material quality, the new structure new aeration host textile fiber aeration tube, has made compound modified processing from the textile fiber material quality, is makes in the craft the process to comb cotton, hotly to stick a coiling multi-channel working procedure formation the porous part, the product is good from the support intensity, the factor of porosity is high, aperture big and distributed even, when aeration movement can reduce in the biochemistry pond the microorganism to adhere to stick cohere, not dirty stops up, extension service life. In the aeration structural design ventilates, slow sufficient, the spreading qi science was reasonable, realizes the resistance to be low, oxygenizement ability, the oxygen use factor higher characteristic, was a modern biochemistry aerator innovation, this product has given the water drainage product quality surveillance test center after the ministry of construction the authority examination.
