Description

Aeration oxidation treatment device for waste water

Technical Field

The utility model relates to a waste water treatment technical field especially relates to an aeration oxidation treatment device for waste water.

Background

Aeration is a means for bringing air into strong contact with water, and is aimed at dissolving oxygen in the air in water or releasing unnecessary gases and volatile substances in the water into the air, and at providing an appropriate environment for aerobic bacteria. In other words, it is a means of facilitating mass exchange between gas and liquid.

However, the existing treatment device has high water flow speed, short retention time in the treatment box and stable water flow, so that the mixing speed of the waste water and the air is poor, the efficiency is low, and the waste water cannot be treated better.

SUMMERY OF THE UTILITY MODEL

To the deficiency of the prior art, the technical problem to be solved by the present patent application is: how to provide an aeration oxidation treatment device for waste water, which improves the treatment efficiency, strengthens the contact between the waste water and the air, is convenient to use and has low cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an aeration oxidation treatment device for waste water, includes the box, box lower extreme one side is provided with the water inlet, box upper end one side is provided with the delivery port, the aeration pipe is installed to the inside lower extreme of box, the last distribution of aeration pipe installs the aeration dish, the aeration dish sets up downwards, the aeration pipe is connected with the trachea outward, the trachea with box fixed connection, it is provided with the guide plate still to go back interval distribution in the box, be provided with the mounting hole on the guide plate, install the filter screen in the mounting hole, it is adjacent the filter screen dislocation set that sets up on the guide plate.

Like this, waste water passes through in the water inlet gets into the box, and aeration dish aeration is rushed into the air, and waste water and air mixing, guide plate carry out the water conservancy diversion to waste water, and the waste water of lower floor passes through the filter screen and gets into the upper strata, and the filter screen can be relaxed the air of gathering, disperses the bubble, reduces the volume of bubble for waste water more abundant with the air contact, provide suitable environment for good oxygen fungus, the treatment effeciency of waste water with higher speed. The filter screen dislocation set for waste water forms the runner of S-shaped in the water tank, prolongs the dwell time of waste water in the water tank, increases the contact time and the processing time of waste water and air, improves waste water treatment efficiency.

Furthermore, the lower surface of the guide plate is concave to form a groove. After waste water impacted the guide plate, under the effect of recess for rivers disperse the disturbance, change original direction, and then make waste water and air contact more abundant, and the treatment effect is better.

Furthermore, the groove is obliquely arranged, and a barb is arranged at the end with the largest groove depth. The recess slope sets up, and the degree of depth is different for waste water mixing rate is higher. The barb is arranged, wastewater entering the barb flows back, and the wastewater which does not reach the position is impacted and mixed, so that the original state of the wastewater is changed, and the contact degree of the wastewater and air is improved.

Furthermore, a support is fixedly installed at the lower end of the inner portion of the box body, and the aeration disc is fixedly installed on the support. The aeration disc can be better installed, and the stability is improved.

Furthermore, the lower surface of the aeration disc is hemispherical, and air holes are distributed on the lower surface of the aeration disc. The air is sprayed downwards, the formed bubbles rise after being decelerated, the retention time of the air in the wastewater is prolonged, and the treatment efficiency is improved.

In conclusion, the device has the advantages of improving the treatment efficiency, strengthening the contact between the waste water and the air, along with convenient use and low cost.
