Abstract

The invention discloses a radial-flow micro-nano air flotation device, which relates to the technical field of water treatment and is used for solving the problems of the need of elevating inflow water for shallow air floatation, complex equipment, high fault rate, unfavorable purifying effect, difficulty in upsizing ordinary dissolved air flotation, difficulty in ensuring the purifying effect, and the like. The radial-flow micro-nano air flotation device provided by the invention comprises a contact area (1), a separation area (2), an outflow channel (3), a slag floating groove (4), a sludge groove (5), a central support post (6), a water inlet pipe (7), a water outlet pipe (8), a dissolved-air water inlet pipe (9), a mud discharge pipe (10), a slag discharge pipe (11), a mud and slag scraping machine (12), a micro-nano bubble generator (13) and the like. The radial-flow micro-nano air flotation device has the outstanding advantages of automatic water inflow, low manufacturing cost, low running cost, good purifying effect, easiness for maintaining, capability of stably running continuously and non-halt overhauling.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an air flotation device. Background technique [0002] Air flotation is a very important water treatment technology. It is widely used in algae removal, oil removal, and suspended solids removal. It is an essential process unit for many wastewater treatment systems. Shallow air flotation is a kind of dissolved air flotation. Its equipment structure is complicated, the failure rate is high, the cost is high, the water intake needs to be raised, and the air flotation effect is not ideal; Blockage, the blockage of individual dissolved air releasers will affect the overall air flotation effect, and it is rare to see examples of large-scale dissolved air flotation running well. Contents of the invention [0003] The invention provides a radial flow air flotation device, which is simple in structure, easy to maintain, low in cost, does not need to be lifted when entering wat...
