Unattended rural sewage treatment AAO (anerobic-anoxic-oxic) integrated tank

Abstract

An unattended rural sewage treatment AAO (anerobic-anoxic-oxic) integrated tank comprises an anerobic hydrolytic acidifying adjusting tank, an anoxic denitrifying tank, a nitrification aerobic aerating tank, a suspending clarifying tank and an oblique tube precipitating tank. The anerobic hydrolytic acidifying adjusting tank is communicated with the anoxic denitrifying tank; the anoxic denitrifying tank is communicated with the nitrification aerobic aerating tank; the nitrification aerobic aerating tank is communicated with the suspending clarifying tank; the suspending clarifying tank is communicated with the oblique tube precipitating tank; one side of the oblique tube precipitating tank is provided with a contact sterilization ditch and a Parshall metering tank; the contact sterilization ditch is communicated with the oblique tube precipitating tank; the Parshall metering tank is communicated with the contact sterilization ditch; the anerobic hydrolytic acidifying adjusting tank isprovided with an inflow pipeline; the Parshall metering tank is provided with an outflow pipeline. The unattended rural sewage treatment AAO integrated tank helps effectively solve the problem that domestic sewage mixed with rural domestic wastewater and little industrial wastewater has great changes in quality and quantity, so that water treatment is non-standard; continuous treatment of wastewater is achieved, the quality of discharged water is stable and standard, and the integrated tank herein occupies small area.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an unattended township sewage treatment AAO integrated pool. Background technique [0002] At present, my country's sewage treatment rate is still low, especially in township sewage, most of which are discharged into surrounding water bodies without any treatment, causing serious pollution of surface and underground water sources. With the promulgation of the national "Water Ten Measures", township sewage has attracted the attention of local governments in various places. However, the outstanding situation faced by township sewage treatment is that the quality and volume of sewage water vary greatly. The peak of sewage discharge in townships is in the morning and evening. In addition, the sewage produced by some township enterprises and small workshops cannot be effectively purified and treated, and is mixed into domestic sewage collection pipes, causing changes in sewag...

AI Technical Summary

Problems solved by technology

[0003] The use of common nitrogen and phosphorus removal biological pools often has the characteristics of low efficiency, large investment in infrastructure and pipeline equipment, large floor area, high sludge treatment costs, and high level of operation and management requirements; and the use of integrated equipment that has emerged in recent years cannot Fundamentally solve the problem that the effluent water quality cannot meet the standard due to large fluctuations in water quality and water volume, and the integrated equipment also has the characteristics of short service life, high level of operation and management requirements, and high operation and maintenance costs.
