Microporous membrane aerator 1980s developed the latest aeration equipment, which aeration bubble diameter is small, gas-liquid interface of small diameter, large gas-liquid interfacial area, the bubbles dispersed evenly, does not clog pores occur, resistance corrosion, the Shanghai Tongji Environmental Engineering College and North China Municipal Engineering depict hospital for water and sewage oxygenation test, and after more than 50 years of use of the role of the user outstanding (custom product than fixed spiral aerators, diffuser aeration and perforated pipe aerator energy consumption decreased by 40%, or 40% of sewage treatment capacity added). Surprising for urban sewage and large factories the new expansion and transformation of the old aeration tank and aeration tank can be intermittent operation. Aerator primary technical parameters: aerator scale: Φ200mm, 260mm serve area: 0.25-0.55m2 / a, 0.35-0.75m2 / aeration uniform pore membrane operation: 80-100 micron air flow: 1.5-3m3 / a total oxygen transport coefficient h: kla (20 ℃) ??0.204-0.337min-1 oxygen utilization :( depth 3.2m) 18.4-27.7% oxygenation to: 0.112-0.185KgO2 / m3h oxygenating power Power: 4.46-5.19KgO2 / kwh Aeration resistance: 180-280mmH2O air duct should be thinking depict the pressure balance, the best together into a ring network, each intake pipe valve should be set to facilitate the amount of air conditioning. Air tube depicts flow rate: dry tube 10-15 m / sec; branch pipe of 5 m / sec. Aeration equipment looks from the bottom height: 270mm, 250mm, push plate is 200mm. [Equipment] 1 order, review equipment construction plans; 2, review site pond construction plans together with the ability to scale; 3, according to the site conditions and drawing actinomycetes; 4, according to the line to fight the expansion bolt, adjustable pipe support equipment; 5, based on scale drawings start cutting pipe cutting; 6, center intake supervisor position, will be supporting the four-way or three-way bond on behalf of the good (Note: Be sure to smooth vertical and horizontal); 7, based on the drawings in azimuth aerator put on a branch pipe line, opening, opening the size of ordinary for 6 ~ 8mm, based on detailed aerator type conclude; (after drilling debris must be finishing clean, can not remain in the pipeline) 8, the branch pipes discharge on an adjustable pipe support, and intake center in charge of bonded together (Note: the branch pipe lay holes must be straight up); 9, the two sides of the interface pipe tee, elbow interface manifold nozzle bonded together. (Note: Be sure to smooth vertical and horizontal) 10, with the level of conditioning adjustable pipe support all piping; 11, adjustable pipe bracket nylon cable ties (on the way to the bar: the nylon tie buckle without holes in the side of the bracket within the slot, and then find the iron pierce nylon tie a square hole about 12mm, the quietly a pressure on the wear of); 12 in the branch pipe perforated adhesive orientation aerator spout ( Note: Be sure to spout aerator straight up); 13, to be strong bonding spout aerator (about 24 hours), and then the device aerator; 14, aeration equipment and piping is completed, in order to avoid Local convergence pipeline leak, the pool water should be placed around the upper part of the aerator to 100mm, then the ventilation quiz, if there is leakage site should sign and promptly repair cook until thoroughly qualified, you can put into use up. 15, focusing matters: ①, in order to avoid other jobs, such as welding sparks and civil construction, such as damage to the aeration equipment, aeration piping system equipment necessary to carry out after the completion of civil works. ②, ABS nozzle can not polish bonding, UPVC spout polished necessary bonding, aeration piping referral using ABS pipe.
