Description

Anaerobic tank for sewage treatment and sewage treatment device

Technical Field

The utility model belongs to the technical field of sewage treatment, concretely relates to an anaerobism pond and sewage treatment plant for sewage treatment.

Background

The anaerobic biological treatment technology is an efficient sewage treatment mode which is characterized in that organic matters in sewage are decomposed, metabolized and digested by anaerobic bacteria in an anaerobic state, so that the content of the organic matters in the sewage is greatly reduced, and meanwhile, methane is generated. Anaerobic treatment, an important form of biological treatment, is developing a series of new anaerobic treatment processes and structures in succession, gradually overcoming the disadvantages of the traditional anaerobic processes and making great progress in theory and practice.

At present, current anaerobic tank for sewage treatment is often relatively poor because of the leakproofness for oxygen content is higher in the pond, reduces anaerobism to sewage purification's effect, and simultaneously, sewage is not convenient for stir in the pond, makes that the microorganism purifies thoroughly, and sewage purification's effect is poor, and in addition, current integration sewage treatment equipment anaerobism pond, oxygen deficiency pond and good oxygen pond etc. all are the intercommunication state, and sewage is comparatively short-lived through each step treatment time, and purifying effect is not good.
