Wastewater treatment system for removing total nitrogen through A-ACMBR process without adding carbon source

Abstract

The invention discloses a wastewater treatment system for removing total nitrogen through an A-ACMBR process without adding a carbon source. The system comprises a primary treatment device main body and a secondary treatment device main body. The system can treat urban sewage, culturing and slaughtering wastewater and industrial organic wastewater with a high solid content, a low carbon-to-nitrogen ratio and a high pollutant content at a low cost and a high efficiency.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage treatment system for removing total nitrogen by an A-ACMBR process without adding carbon sources, and belongs to the field of sewage treatment systems. Background technique [0002] With the acceleration of my country's urbanization process, the amount of urban sewage discharge and its proportion are also increasing year by year, and the demand for urban sewage treatment is increasing day by day. The main chemical composition of urban sewage is organic compounds, including proteins, lipids, sugars, organic acids, alcohols that are easily degraded by microorganisms, and natural organic substances such as cellulose and lignin that are not easily degraded; , soluble salts, etc. In recent years, with the adjustment of my country's agricultural structure and the advancement of agricultural industrialization, the large-scale and intensive livestock and poultry breeding industry ha...

AI Technical Summary

Problems solved by technology

There are still the following problems in the application process: ①The amount of sludge is large, which is difficult to treat and dispose of; ②The sewage reuse rate is low; ③The construction area of ​​the traditional activated sludge method is large.

[0007] 1. The overall operating costs of sewage plants, factories, and farms have been ignored in the research process of certain technical equipment and processes, resulting in high operating and management costs that have become a restrictive factor for the normal operation of wastewater treatment;

[0008] 2. The substandard total nitrogen discharge caused by the low carbon-nitrogen ratio has become a major problem affecting the operation of the sewage treatment system;

[0009] 3. The discharge of wastewater is not controlled from the source, which increases the difficulty and cost of wastewater treatment, and does not conform to the idea of ​​a sustainable society
