Problems solved by technology

[0006] Although the above-mentioned biological treatment uses the activated sludge process, when this process treats nitrogen, it can only convert organic and ammoniacal nitrogen into nitrous acid or nitrate nitrogen form, and the final treatment of reduction cannot be expected. Phosphorus treatment efficiency is also low, making it a major problem in water quality management for conservation of wat

Abstract

The invention relates to an advanced wastewater treatment device using the sequenching batch process including the wastewater inflow - microbial reaction - precipitate - evacuation step gets accomplished of the series of procedure. The advanced wastewater treatment device using the sequenching batch process comprises an SBR, ta fixed carrier, and a membrane bioreactor (MBR). In the SBR is the outside, it is provided with wastewater and the aerobic reaction, the aerobic reaction, and the anaerobic reaction are performed through the control unit in which the unattended operation is possible. Thefixed carrier is installed within SBR and multiple air gaps are formed and the microorganism is adhered to the air gap and exterior. The membrane bioreactor (MBR) is installed in the upper portion within SBR and the processing water is ejected to the outside after wastewater is solid from liquid separated to sludge and processing water.

Description

technical field [0001] The invention relates to a high-level sewage treatment device using a sequence batch reactor (SBR, sequence batch reactor) process. The above-mentioned sequence batch reactor process includes a series of processes of sewage inflow-microbial reaction-precipitation-discharge. Background technique [0002] In order to protect the land and prevent water pollution and soil pollution, the government enacted the Sewerage Act to manage polluted water such as sewage. In particular, Article 7 of the Sewerage Act of Korea establishes water quality standards for discharged water. According to Article 3 of the implementation rules of the sewer law based on this standard, biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended matter (SS, Suspended Solid), total nitrogen (T-N), and total phosphorus (T-P ), the total number of coliform bacteria as targets, and establish the following water quality standards for the discharge water of public sewage t...
