Apparatus and method for treating high-ammonia nitrogen rural biochemical sewage based on SBBR process

Abstract

The invention relates to an apparatus and a method for treating high-ammonia nitrogen rural biochemical sewage based on an SBBR (sequencing batch biofilm reactor) process. The apparatus comprises an SBBR, a PLC, and a DO sensor, an ORP sensor, a pH sensor, a temperature sensor and a static pressure liquidometer which are arranged in the SBBR; a filler in the SBBR comprises a plurality of nylon ropes suspending in the SBBR, every nylon rope is fixedly provided with a plurality of fillers A and fillers B, every filler A and every filler B are surface cation modified high-density polyethylene materials, and the fillers A and the fillers B are alternately distributed; every filler A is has a disk shape, and an inner fan blade and an outer fan blade are arranged in every filer A in a turbine blade form; and every filler B has a radial fiber structure. The quality of effluent water treated with the apparatus and the method can reach first-grade A standards in Discharge Standard of Pollutantsfor Municipal Wastewater Treatment Plant (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
