Ecological engineering effectively controlled urban zoo pollution from diffuse and small point sources. Both online and offline modes significantly improved runoff water quality and pollutant retention, with the online mode showing higher efficiency.

Area of Science:

  • Environmental Engineering
  • Urban Ecology
  • Water Resource Management

Background:

  • Urban pollution from diffuse and small point sources, particularly in zoos, is a significant environmental challenge.
  • Control strategies for such pollution have historically received limited research and implementation.
  • Ecological engineering offers potential solutions for managing complex urban pollution scenarios.

Purpose of the Study:

  • To design and evaluate online and offline ecological engineering technologies for controlling pollution from small point and diffuse sources in an urban zoo.
  • To investigate the characteristics and performance of these systems during various runoff events.
  • To compare the effectiveness of online versus offline modes in improving water quality and retaining pollutants.

Main Methods:

  • Implementation of online and offline ecological engineering systems in Wuhan City Zoo.
  • Monitoring and analysis of sixteen runoff events between 2003 and 2005.
  • Measurement of event mean concentrations (EMCs) for total suspended solids (TSS), chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP).
  • Calculation of pollutant load retention rates and runoff storage capacities for both modes.

Main Results:

  • Both online and offline modes significantly improved runoff water quality, reducing EMCs of TSS, COD, TN, and TP.
  • The online mode achieved higher reductions (e.g., 88% TSS) and annual pollutant load retention (94.9%-98.5%) compared to the offline mode (e.g., 77% TSS, 70.5%-86.4% retention).
  • The online mode could store runoff from 66.7 mm rainfall, while the offline mode stored 31.3 mm, demonstrating substantial water retention capabilities.

Conclusions:

  • Online and offline ecological engineering are effective strategies for managing diffuse and small point source pollution in urban environments like zoos.
  • The online mode offers superior pollutant removal, water retention, rainwater utilization, habitat creation, and aesthetic value.
  • The offline mode presents a land-saving, economical, and effective alternative for diffuse pollution control in urban areas.
