Description

Biological pond floating mud clearing device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a floating mud removing device for a biological pond.

Background

In sewage treatment processes, the activated sludge process is one of the most common. However, in the biochemical pool, the aged activated sludge can cause partial microorganism activity to be poor and even die, and the disintegrated zoogloea forms adhesive bubbles to float on the surface of the pool.

The floating of sludge is caused by the following reasons: 1. too large aeration amount: excessive aeration can accelerate the self oxidation, metabolism and even death of the activated sludge, so that the activity is reduced; 2. the sludge discharge amount is too low: the sludge aging probability is improved due to the over-low sludge discharge amount; 3. the quality of inlet water fluctuates: the inorganic components in water are high and are difficult to be degraded by microorganisms. Particularly in rainy season, a large amount of inorganic silt is brought by rainwater, so that the organic components of the activated sludge are reduced, and further the real sludge load of the biochemical pond is reduced. Carbohydrate contained in the sewage can cover the surfaces of zoogloea microorganisms, so that the volume of the sludge is increased, the sludge-water separation effect is poor, and the sludge floats upwards easily. 4. Effects of Actinomycetes: actinomycetes are aerobic bacteria and grow under conditions of high dissolved oxygen content. The aeration quantity is too large, and the actinomycetes are easy to grow. Polysaccharide substances decomposed by aerobic actinomycetes have certain viscosity, and can float upwards along with aeration bubbles to form a plurality of floating sludge around the bubbles. The floating mud in the biochemical pool has a plurality of small holes which are the effect of the action of bubbles.

At present, the method for solving the problem of floating mud in the biochemical tank comprises the following steps: 1. stabilizing the quality of inlet water; 2. the addition of a carbon source is considered, and the organic load rate is improved; 3. reasonably discharging the mud; 4. the aeration quantity is reasonably adjusted. The above are all solutions proposed from the root cause of the floating mud production. However, the above methods have no specific operation specifications, and operators can adjust the floating mud according to the conditions and experiences of the field, so that the floating mud cannot be removed certainly and cannot be eliminated.

In addition to the above mentioned methods, there are other solutions which are directed only to floating sludge: the sludge is scattered by sprinkling water, partial sludge particles recover settleability, but partial sludge is still likely to be gathered and float; the coagulant adding method only delays the floating mud phenomenon.

Therefore, in any of the above solutions, the adjustment is performed by a large amount of manpower and material resources, and the mud floating phenomenon cannot be completely eliminated.
