(1) the amount of air: the design of the amount of air contact oxidation can remove the need to inject air per kgBOD 70 ~ 90Nm3 calculations can also be water-gas ratio of 1: 8 to 1:12 calculations. The need to maintain the operation of the aeration tank dissolved oxygen concentration DO = 2.5 ~ 4.0mg / L can be. (2) there is water in the aeration tank due to buoyancy, sedimentation tanks inclined tube filler can remain stable in the grid holder, but when the venting If water tanks, due to the filler attached about 300kg per m3 of raw sludge, In order not to load all added to the filler, filler cause bending or grill stent deformation accident fiberglass honeycomb inclined tube, the need to vent sewage while packing pressure water rinse, so adhere to it on the raw sludge with water discharge . (3) sedimentation inclined tube filler suitable water temperature is 5 ℃ ~ 40 ℃, within which there is a very tough material properties, will not be deformed. But while working at below 5 ℃ cellular inclined tube, due to the increase of its hardness, impact resistance variation, need to choose anti-cold brittle material additives. Another long outdoors under direct sunlight exposure, the filler will be caused due to UV aging, resulting in reduced strength. If you must use in outdoor exposure under, shall be specified using weather-resistant, anti-aging products. General packing should be stored in the yard have awnings to prevent long-term sun, and to avoid freezing. Users often buy cellular inclined tube filler are aware, when the purchase of cellular inclined tube filler hexagonal honeycomb inclined tube, inclined tube selection is the most important in all conditions. Because proper cellular inclined tube filler can not only improve work efficiency, but also reduce overhead costs, so the cellular inclined tube filler selection is one of the factors to consider are the first user. Then someone will ask: "? If the election is less than the appropriate cellular inclined tube filler happen," the answer is obvious cellular inclined tube filler, inappropriate cellular inclined tube filler does not only improve efficiency, but will be reduced, along with the use of the cost will be increased gradually to allow cellular packing seal leakage, leakage direction requirements; life and reliability requirements are very high demands. It is proposed that we must choose carefully! Ethylene-propylene copolymer cellular inclined tube, Song Xin cellular inclined tube plant (certified), Mudanjiang cellular ramp provided by Gongyi City Song Xin Industrial Co. filter.
