二、Shallow air flotation rotary disc refined filter tank integration working principle
1.Dissolved air tank to produce dissolved air water, dissolved air water released to the water to be treated through releaser decompression (by dosing and fully mixed) in the tank, dissolved in the water from the air released from the water, the formation of 20-40um tiny or even smaller micro bubbles, micro bubbles with suspended solids in sewage (SS) combined, so that the specific gravity of suspended solids less than water, and gradually float to the surface to form scum.
2.The upper part of the shallow air flotation device is equipped with a scraper system. The floating slag which on air flotation to the water surface is scraped into the sludge hopper and imported into the sludge collection tank.
3. The clean water under the shallow air flotation tank passes through the rotary disc refined filter device which is configured in the lower part of the tank, collect clean water and self-press it into the rotary disc refined filter device, and imports it into the clear water tank after filtration.
4.The surface of rotary disc refined filter is equipped with suction nozzle regeneration system, which adsorbs sludge on the surface of rotary disc refined filter and is not easy to be blocked, keeping the stable flux of clear water of rotary disc refined filter.
三、Main features and advantages of the product
1.High efficiency shallow air flotation rotary disc refined filter tank device is widely used, set "dosing and mixing flocculation, dissolved air and release, air flotation tank body, mud scraping device, rotary disc precision filtration, filter disc adsorption regeneration and other functions" for integrated water treatment equipment, and equipped with automatic adjustment and intelligent control system, maximum space saving, can be used Semi-enclosed or fully enclosed mode of operation. It is mainly used for the removal of micro solid suspension, grease or various colloidal substances in sewage, such as: raw water pre-treatment in printing and dyeing industry, precision treatment before water reuse, industrial wastewater air flotation treatment, etc.
2.High efficiency shallow air flotation rotary disc refined filter tank device has low velocity of air flotation water flow, the speed of water relative to the wall of the tank is close to zero speed, there is no stirring of the water in the tank, which makes the particles in the water float up or settle under more static, high degree of purification, the removal rate of suspended matter is higher than other air flotation 20-30%. There are "rotary disc fine filtration" and "adsorption regeneration" devices under the air flotation tank, and the turbidity and SS of the water treated by this device can reach higher indexes than other air flotation indexes.
3. High efficiency shallow air flotation rotary disc refined filter tank device compared with ordinary conventional air flotation device and filtration device, in addition to the small size of the equipment itself, but also does not require additional civil construction, equipment is easy to transport and installation, with a high degree of flexibility, in today's "inch of land is like gold" era, greatly reducing the footprint of the water treatment system, and no longer need to pass the sand filter, intermediate tank, backwash and other facilities, reducing the investment costs and operating costs of water treatment, highlighting the excellent water quality, high efficiency, energy saving.
4.High efficiency shallow air flotation rotary disc refined filter tank device adopts new dissolved air and release components, with relatively high dissolved air utilization rate, good air flotation effect and less flocculant dosing, which better reduces the operation cost. Before entering the rotary disc refined filter device, the turbidity index of water has reached 3~4NTU, after passing through the rotary disc refined filter device, the turbidity of water is less than 1~2NTU index, which can reach higher water standard.
5.The new shallow air flotation rotary disc filter tank integrated device to deal with high water yield and stable quality indicators, the effective treatment flux of air flotation can reach 16~18m3/m2*h, is 5 ~ 6 times of the conventional air flotation device, is 3.5 ~ 4 times of the round tank shallow air flotation device, high efficiency air flotation refined filter tank with ordinary air flotation device and shallow air flotation performance efficiency comparison table is as follows.

6. The new shallow air flotation rotary disc filter tank integrated device has higher automation and intelligent functions, easy to operate, easy to master cleaning and maintenance, water quality and water quantity is easy to automatically control and intelligent adjustment, with a perfect slag and mud discharge system, the overall management and operation management is very simple, and the use of fully automatic control, not affected by human operation, reduce labor intensity and reduce operating costs.
7.The water quality is greatly improved and enhanced by the fine filtration of the air floatation discharge water through the rotary disc, which also improves the water quality into the dissolved air pressure tank, avoiding the phenomenon that the dissolved air pressure tank, jet nozzle and release device are easily blocked.
8.The material of the filter cloth on the fine filtration turntable, the base cloth is polyester fiber, the free base is polyamide material, the density of the filter cloth and the length of the villus on the surface of the filter cloth can be selected according to the filtration medium, the filter cloth medium has an effective filtration depth of 2mm, the filtration Water throughput is not less than 15-20m3/m2/h, the filter disc is uniform overall surface, the dense filter layer capable of forming flocs reaches 5 ~ 8um filtration accuracy, the fine filtration effect is high.
