A kind of high ammonia nitrogen rural biochemical sewage treatment device and method based on sbbr process

Abstract

The invention relates to a high ammonia nitrogen rural biochemical sewage treatment device and method based on the SBBR process. The device includes a SBBR reactor, a PLC controller, and a DO sensor, an ORP sensor, a PH sensor, a temperature sensor and a static pressure sensor installed in the SBBR reactor. type liquid level gauge; the filler in the SBBR reactor includes several nylon ropes suspended in the SBBR reactor, and several filler A and filler B are fixed on each nylon rope, and the filler A and filler B All are high-density polyethylene materials with surface cation modification, and filler A and filler B are distributed alternately; the filler A is in the shape of a disc, and the inside of filler A is arranged with inner fan blades and outer fan blades in the form of turbine blades. leaves; the filler B has a radial fiber structure; the quality of the effluent treated by the device and the process method of the present invention can reach the first-class A standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" GB18918‑2002.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-ammonia-nitrogen rural biochemical sewage treatment device and method based on the SBBR process, which is suitable for the treatment of high-ammonia nitrogen sewage in rural areas and small towns with small scale, scattered points, and large fluctuations in water quality and water volume. Background technique [0002] In recent years, with the rapid development of the country's economic development, the development of rural construction has also shown a vigorous upward trend; the country has also paid more attention and requirements to the improvement of the rural ecological environment and the treatment of domestic sewage, and put forward specific plans Goals, remediation scope and fields, emphasizing the key remediation of rural drinking water sources and rural domestic sewage. [0003] With the continuous improvement of rural economic level and the improvement ...

AI Technical Summary

Problems solved by technology

At present, most rural areas in my country (more than 95% of villages and more than 90% of small market towns) lack systematic pipe network drainage and complete sewage treatment facilities. Most of the sewage is directly or simply treated by septic tanks. Discharged to rivers or outdoors, bringing direct pollution and serious hidden dangers to soil, rivers and groundwater

[0004] Due to the geographical location, industrial layout and economic status of the countryside are all different, there is no unified reference standard, so its own sewage discharge points are scattered, small in scale, and water quality varies greatly. The particularity of rural sewage determines the traditional conventional treatment methods will be very limited
