Abstract

The utility model relates to an air floatation wastewater treatment device which comprises a water pump, an air compressor, a pressure dissolved air vessel and a dissolved air water pipeline, wherein the pressure dissolved air vessel is connected with the water pump and the air compressor, and one end of the dissolved air water pipeline is communicated with the pressure dissolved air vessel. The air floatation wastewater treatment device is characterized in that one end of the dissolved air water pipeline, which is far from the pressure dissolved air vessel enters an air flotation tank from the upper portion of the air flotation tank, and two baffle plates are arranged in the air flotation tank. One end of the dissolved air water pipeline, which is far from the pressure dissolved air vessel is divided into a plurality of branch pipes which are distributed in a step shape on the horizontal direction, the branch pipes are arranged on the upper portion of the air flotation tank in parallel, the end of each branch pipe vertically enters the air flotation tank in 90 degrees bending, and the branch pipes which enter the air flotation tank are provided with a releaser. The air floatation wastewater treatment device has simple structure, is convenient to clean water outlet holes of the dissolved air water pipeline, and has high work efficiency.

Description

A kind of air supporting sewage disposal device
Technical field
The utility model relates to a kind of water treating equipment, particularly a kind of air supporting sewage disposal device.
Background technology
The general air supporting sewage disposal device that adopts carries out mud-water separation in the sewage disposal at present.Existing air supporting sewage disposal device is by feeding dissolved air water in the air flotation pool bottom, realizing solid-liquid separation.The problem that exists is: have the posticum that impurity stops up the reliever on the dissolved air water pipeline easily in the dissolved air water.In case this situation occurs, just the water of air flotation pool need have been arranged entirely, again the posticum of dissolved air water pipeline to be cleared up, this is a ubiquitous problem in the present sewage disposal.Simultaneously, air supporting is handled one-level or two-stage generally only is set, and does not sometimes reach good solid-liquid separation effect.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, convenient, higher air supporting sewage disposal device of working efficiency of dissolved air water pipeline posticum cleaning.
A kind of air supporting sewage disposal device, the pressure air-dissolving tank that comprises water pump, air compressor, is connected with air compressor with water pump, the dissolved air water pipeline that an end is communicated with pressure air-dissolving tank, it is characterized in that: described dissolved air water pipeline enters air flotation pool away from the pressure air-dissolving tank end from the top of air flotation pool, is provided with two dividing plates in the air flotation pool.
Described dissolved air water pipeline is divided into the arm of several stepped distributions in the horizontal direction away from the pressure air-dissolving tank end, these arms are set in parallel in the air flotation pool top, the end of each arm becomes 90 degree bendings vertically to enter air flotation pool, and the arm that enters air flotation pool is provided with reliever.
All be provided with control valve on each arm further.
Because the dissolved air water pipeline enters air flotation pool from the top of air flotation pool, so in the time need clearing up to the posticum of dissolved air water pipeline, only need close the control valve that is arranged on the dissolved air water pipeline, the dissolved air water pipeline of band reliever part is taken out, clear up, do not clear up and do not need air flotation pool emptied, cleaning is got up more convenient.Adopt the dissolved air water arm of a plurality of stepped distributions, carry out multistage molten gas disposal, can effectively improve pneumatically supported efficient, and be provided with two dividing plates in the air flotation pool and be equivalent to air supporting and handled three times, solid-liquid separation effect is better.

Fig. 2 is the vertical view that the dissolved air water pipeline is arranged.
Fig. 3 is a dissolved air water pipeline synoptic diagram.
Embodiment
Referring to Fig. 1, Fig. 2:
A kind of air supporting sewage disposal device, comprise water pump 1, air compressor 2, the pressure air-dissolving tank 3 that is connected with air compressor 2 with water pump 1, the dissolved air water pipeline 4 that one end is communicated with pressure air-dissolving tank 3, these dissolved air water pipeline 4 the other ends are divided into the arm 41 of eight stepped distributions in the horizontal direction, these arms are set in parallel in air flotation pool 5 tops, the end of each arm becomes 90 degree bendings vertically to enter air flotation pool 5, the arm 41 that enters air flotation pool 5 is provided with reliever 6, all be provided with control valve 7 on each arm 41, be provided with two dividing plates 8 in the air flotation pool, dividing plate 8 is perpendicular to 5 ends of air flotation pool.
Mode of operation of the present utility model: recirculation water is squeezed into pressure air-dissolving tank 3 by water pump 1, and constantly to pressure air-dissolving tank 3 bubbling airs, the air in the pressure air-dissolving tank 3 is dissolved in water to air compressor 2 under pressure, and the state that reaches capacity, and forms dissolved air water.Dissolved air water enters air flotation pool 5 by the arm 41 of dissolved air water pipeline 4, discharges a large amount of bubbles in air flotation pool 5 bottoms by reliever 6 decompression suddenly and adheres in the water on the suspended substance, and the whole proportion of suspended substance is emerged less than water, aggregates into mud.The arm 41 of stepped distribution has guaranteed the abundant of bubble, makes the suspended substance separation of fully floating.After using for some time, when the water outlet of reliever 6 was stopped up by the impurity in the dissolved air water, closed control valve 7 took out the dissolved air water pipeline of reliever 6 parts from air flotation pool 5, install back after cleaning up in the air flotation pool 5.
