Abstract
The invention relates to the field of surface source pollution control technology, and particularly relates to a new combined process for carrying out point-line-surface stereo technical configuration and process treatment of rural and agricultural surface source pollutants to achieve first-level B standard requirements of 'Urban Sewage Treatment Plant Pollutant Discharge Standard' (GB 18918-2002). Aiming at the characteristics that rural and agricultural surface sources have wide space-time range, large non-determinacy, more complex composition and procedures, and difficult control, the new combined process starts from a source-flow-convergence procedure of loss of nitrogen and phosphorus, simultaneously considers a study area topography and a geomorphic feature, successively arranges a point-line-surface-based denitrification and dephosphorization combination process procedure and a key technology along a pollutant migration path, is characterized by comprising (1) a point type configuration (pretank treatment) technology, (2) a linear type configuration (ecological interception optimized based on a hydraulic power structure) technology and (3) a surface type configuration (combination of deep pond anaerobism and shallow pond aeration) technology, and realizes an objective of beautifying farmer residential areas and agricultural area landscapes while reducing pollution loads.
