Abstract

The utility model belongs to an air-floating waste water treating device, comprising a rotational flow reaction chamber, a vertical flow air-floating separation chamber, etc., and is characterized in that the utility model is also provided with a conical section table concentrating and dregs overflowing board which can lead waster dregs which float upwards to be further dewatered in a dreg gathering zone, to overflow from an overflow port of the board and to be discharged out of the device. The utility model has the advantages of low water content of dreg discharging, the reduction of the cost of waste water treatment and the reduction of energy consumption. The utility model obtains satisfactory effect in the course of waste water treatment of printing and dyeing.

Description

Automatic concentration dregs overflowing type waste water treating apparatus

The utility model belongs to the improvement of air supporting wastewater treatment equipment.

Existing air supporting wastewater treatment equipment is with mixing and reaction chamber and air flotation separating chamber design mix body structure formula.Air flotation separating chamber deslagging mode adopts machinery to scrape slag or overflow and slag usually.Machinery is scraped slag equipment cost height, the running maintenance complexity, and conventional overflow and slag water ratio is higher, mud handling capacity is big.

The purpose of this utility model is to provide a kind of dregs overflowing type wastewater treatment equipment that concentrates automatically, and this device is designed to collect the cyclone reaction chamber, and the floating separate chamber of perpendicular gas is the structural formula of one with concentrating the grit chamber of overflowing automatically.

The utility model is compared with existing technology, it is characterized in that being provided with overflow garden frustum structure and replaced mechanical doctor or straight tube natural style overflow device in device.

Accompanying drawing is the utility model structural representation, and wherein 1 is housing, is provided with taper dividing plate 2 at the lower part of frame certain position, which is provided with guide shell 3, and tube is built-in with dissolved air release 4.Be provided with taper at housing top certain position and cut the concentrated slag-overflowing plate 5 of platform, this section platform height is 200-300mm.Taper dividing plate 2 and taper cut the concentrated slag-overflowing plate 5 of platform shell space are divided into three chambers; One is the following cyclone reaction chamber 6 that is made of at the bottom of with shell the taper dividing plate, one to be intermediary cut platform by taper dividing plate 2 and taper concentrates the floating separate chamber 7 of perpendicular gas that slag-overflowing plate 5 constitutes, and another is cutting platform by taper and concentrating the deslagging chamber 8 that slag-overflowing plate 5 constitutes with housing top of top.Be provided with wastewater inlet pipe 9 in the bottom of cyclone reaction chamber 6, the waste water of required processing is indoor from tangentially spraying into, and realize the coagulating of impurity in medicine and the water with the eddy flow state, the throw out that reaction generates enters guide shell 3 with water with the alumen ustum shape, the micro bubble of emitting with reliever in tube interacts, absorption mutually, one track overflow guide shell enters air flotation separating chamber 7 and realizes separating of throw outs (waste residue) and clear water, clear water enters following clear water zone, and is collected through rising pipe 11 to water by annular header 10 and to go out groove 12 again outside the discharger.The waste residue of come-up accumulates in the slag-collecting area on top, separate chamber, and waste residue cuts platform outlet overflow through thickening to deslagging chamber 8, again outside scum pipe 13 dischargers through taper.For the ease of washing unit, on the lower case of cyclone reaction chamber and the floating separate chamber of perpendicular gas, be respectively equipped with blow-down pipe 14 and 15.

The utility model deslagging water ratio is 96-97%, than the low 2-3 percentage point of the excessive slag water ratio of routine, in addition, owing to adopt overflow and slag to replace the slag of scraping of machinery, has saved equipment and maintenance cost, has reduced the cost and the energy consumption of processing waste water.The utility model is used for treatment of dyeing wastewater and has obtained well-content effect.

Claims

1, a kind of dregs overflowing type wastewater treatment equipment that concentrates automatically, be provided with the taper dividing plate by housing with in the intravital bottom of shell, dividing plate is provided with guide shell, be placed with dissolved air release in the tube, and wastewater inlet pipe, annular clear water header, rising pipe constitute, and it is characterized in that, the slag-collecting area on the top, the floating separate chamber of perpendicular gas of this device is provided with that a kind of section platform is high to cut the concentrated slag-overflowing plate of platform for the taper of 200-300mm.
