Description

High-efficient sewage treatment device based on biological method

Technical Field

The utility model relates to a sewage treatment technical field, more specifically say, the utility model relates to a high-efficient sewage treatment device based on biological method.

Background

The sewage treatment can be divided into a physical method, a biological method and a chemical method according to the functions of the sewage treatment. The biological method is to utilize the metabolism of microbe to decompose and oxidize the dissolved or colloidal organic matter into stable inorganic matter to purify sewage. Commonly used are an activated sludge process and a biofilm process. The biofilm process is a sewage treatment process for stabilizing and clarifying wastewater by using a biofilm under the condition of sufficient oxygen supply. The carrier (generally called as filler) for microorganism growth and aggregation is arranged in the sewage treatment structure, under the condition of oxygenation, the microorganism is attached to the surface of the filler to form a biological membrane, and when the oxygenated sewage (an oxygenation device is composed of a water treatment aeration fan and an aerator) flows through the filler at a certain flow rate, the microorganism in the biological membrane absorbs and decomposes organic matters in the water, so that the sewage is purified, the microorganism is proliferated, and the biological membrane is thickened. When the biological membrane grows to a certain thickness, oxygen diffusing to the interior of the biological membrane is limited, the surface of the biological membrane is still in an aerobic state, and the inner layer is in an anoxic or even anaerobic state, and finally the biological membrane falls off. And then, a new biological film continues to grow on the surface of the filler, and the process is repeated in cycles, so that the sewage is purified.

After the microorganisms are gathered and attached on the surface of the filler to form the biological film, a thin water layer exists on the surface of the filler due to the adsorption effect of the biological film, and organic matters in the water layer are oxidized and decomposed by the biological film, so that the concentration of the organic matters in the water layer is much lower than that of inlet water.
