Abstract
The utility model discloses an asymmetric streaming air flotation device, comprising an air compressor, a dissolved air tank and a sediment scraper, wherein the asymmetric streaming air flotation device also comprises a two-sections air flotation machine; the two-section air flotation machine comprises an air flotation machine I and an air flotation machine II which are connected in series; a water outlet of the air flotation machine I is connected with a water inlet of the air flotation machine II; and the air flotation machine I and the air flotation machine II are connected with the same dissolved air tank. The high-concentration wastewater which is difficult to treat is well treated by a multi-section air flotation device, and the staying time of wastewater is increased according to the rear section of a pool body with an increased wastewater concentration parameter after treatment of the first section of proper processing capacity section. Thus, the burden of biochemical treatment is reduced and the effect of better effluent quality is achieved.
Description
Technical field
The utility model belongs to environment-protective water treatment and purification equipment technical field, is specifically related to a kind of two section air-floating apparatus.
Background technology
At present, in general waste water treatment process, use air-floating apparatus, great majority are all used coagulating sedimentation air supporting integrative machine now.An air-floating apparatus is installed, is only aimed at lower concentration, fixedly suspended substance simple tractable general waste water less, when running into high density, during waste water that suspended substance is many, water quality is severe, the workload of an air floatation machine just not, the effect of processing is just bad, has also increased the weight of the processing load of subsequent technique.If install two or many, often because separate unit processing power is the same, the size of same engineering system separate unit pond body is the same, dwell time of sewage is the same, treatment effect does not have large variation, has just increased the air supporting of the equal residence time, walks for one more backward, clearance is lower, and very difficult realization increases substantially the effect of effect.
Summary of the invention
The object of the invention is to overcome problems of the prior art, provides the asymmetric crossfire of a kind of multistage pneumatically supported device.
Object of the present invention can be achieved through the following technical solutions: a kind of multistage crossfire air-floating apparatus, comprise air compressor machine, dissolving, slag scraper, also comprise two sections of air floatation machines, two sections of described air floatation machines are connected by air floatation machine I and air floatation machine II, the water outlet of air floatation machine I is connected with the water-in of air floatation machine II, and air floatation machine I is connected with same dissolving with air floatation machine II.
Preferably, described air floatation machine I and air floatation machine II share a slag scraper, and slag scraper drives two dreg scrapers to realize and synchronously scrapes slag.
Preferably, between described dissolving and air floatation machine II, be provided with air dissolved pump, the clear water that air dissolved pump extracts in air floatation machine II enters dissolving.
The beneficial effects of the utility model: the utility model is to make high density, unmanageable water treatment effect better by multistage air-floating apparatus, from the processing of first section of applicable processing power section, by the back segment pond body strengthening according to concentration of wastewater parameter, strengthen the residence time, thereby alleviated the burden of biochemical treatment, reached the better effect of effluent quality.
Accompanying drawing explanation
Fig. 1 is that Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, multistage crossfire air-floating apparatus of the present utility model, comprise air compressor machine 1, dissolving 2, slag scraper 6, also comprise two sections of air floatation machines, two sections of described air floatation machines are by air floatation machine I 5 and 10 series connection of air floatation machine II, and air floatation machine I 5 is connected with raw wastewater water-in 4, and the water outlet 8 of air floatation machine I 5 is connected with the water-in 9 of air floatation machine II 10, air floatation machine II 10 is provided with the Graceful mouth of a river 11, and air floatation machine I 5 is connected with same dissolving 2 with air floatation machine II 10.Air floatation machine I 5 and air floatation machine II 10 share a slag scraper 6, and slag scraper 6 drives two dreg scrapers 7 to realize and synchronously scrapes slag.Between dissolving 2 and air floatation machine II 10, be provided with air dissolved pump 12, the clear water that air dissolved pump 12 extracts 10 li of air floatation machine II enters the molten gas water-in 3 of dissolving 2.
