Description

Aeration device for biochemical tank

Technical Field

The utility model relates to the field of sewage treatment, in particular to an aeration device for a biochemical pool.

Background

In the sewage treatment process, a common method is to add various bacterial strains into the sewage to decompose pollutants in the sewage to reach the discharge standard. In this process, since many strains belong to aerobic bacteria and require a large amount of oxygen supply to exist in the large volume of sewage, it is necessary to use an aeration apparatus. Aeration refers to the process of forcibly transferring oxygen in the air into the liquid in order to obtain sufficient dissolved oxygen. In addition, the aeration also can prevent the suspension in the tank from sinking, and strengthen the contact of the organic matters in the tank with microorganisms and dissolved oxygen. Thereby ensuring the oxidation and decomposition of the organic matters in the sewage by the microorganisms in the tank under the condition of sufficient dissolved oxygen.

The existing tubular aerator is complex in structure and divided into a plurality of groups of independent short pipes, the short pipes are arranged on a supporting pipe arranged above the short pipes at equal intervals for aeration, the weight of the whole device is relatively large, and the number of consumed pipes is large. The aeration pipe both ends are unsettled, and anti rivers and impact nature are relatively poor, and the gland at both ends drops easily and is difficult to clear up, need consume great labour cost during the change.

Compared with a pipe type, the disc type microporous aerator is more complex to manufacture, has limited oxygenation parts, is easy to accumulate mud, and has a complex air distribution system, large air resistance loss and high energy consumption; and when the ventilation capacity is too large, the pressure ring of the disc type microporous aerator is easily blown off.

The microporous tube type aerator adopts the air guide groove, so that air distribution in the aerator is rapid and uniform, the aeration membrane tube is uniformly stressed, the service life of the aeration membrane tube is prolonged, the uniformity of released bubbles is improved, and the aeration effect is improved; the air guide groove is a narrow groove, the area of the rubber film pipe on the air guide groove is not provided with an aeration hole, and when the air supply is stopped, the rubber film is tightly attached to the air guide groove, so that the sewage is prevented from flowing backwards.

However, the pores of the micropores are smaller in diameter and contain Na in the treatment₂SO₄When the temperature in the biochemical tank is reduced during the sewage treatment, Na₂SO₄Can be separated out to block the air hole, the aeration device can not generate oxygen uniformly after the micro-hole is blocked, and the suspension body around the blocked micro-hole can not float and sink along with the discharge of the oxygen, and can be accumulated at the bottom of the tank to influence the local microorganism to play a role, so that the component to be treated in the sewage can not be completely decomposed, and the time for treating the sewage is prolongedAnd (3) removing the solvent. For the aeration holes with larger aperture, the blocking probability is very small, but the total amount of output oxygen is increased due to the enlargement of the air holes, the energy waste is caused, and the cost is increased.
