摘要

This test represents a water quality improvement exemplary project in relation to a tributary section of the Maozhou River located within the Bao'an District, Shenzhen, China. It uses in situ pollution control, aeration, and biofilm combined technologies to treat black and odorous water in situ. Three kinds of aeration equipment are used in the test project: a micronano aerator, push-flow aerator, and jet aerator. The operation results show that the micronano aerator is better than the push-flow aerator, and the push-flow aerator is better than the jet aerator. Three biological fillers were used in the test project: carbon fiber grass, AquaMats ecobase, and biological ribbon. The operation results show that the carbon fiber grass is better than the AquaMats ecobase, and the AquaMats ecobase is better than the biological ribbon. After processing, it was found out that the later transparency, dissolved oxygen (DO), oxidation-reduction potential (ORP), Ammonia nitrogen content index (NH3-N), dichromate oxidizability (CODcr), and biochemical oxygen demand (BOD5) all could comply with the requirements of treatment, indicating that the combined technology is practically viable. The combination technology can provide valuable reference for the treatment of urban black and odorous water. (c) 2020 American Society of Civil Engineers.
