A certain amount of Scenedesmus obliquus and Daphnia pulex was cultured in the system for the control of serious cyanobacterial bloom. The AAFW system was a continuous-flow system including one storage basin of 3 m<sup>3</sup> capacity with polluted river water (the total nitrogen-TN: 4.49 mg⋅l<sup>-1</sup><sup></sup>;the total phosphorus-TP: 0.192 mg⋅l-1</sup></sup><sup></sup>), one phytoplankton tank of 3 m<sup>3</sup> capacity with an initial concentrations of S. obliquus about 5.8 × 10<sup>3</sup> ind⋅l-1</sup><sup></sup>, and one zooplankton growth chamber of 1.5 m<sup>3</sup> capacity with an initial abundance of D. pulex about 22.5 ind⋅l-1</sup></sup>. The system was optimized by setting hydraulic retention time of phytoplankton tank as 5 days and the experiments were operated for 45 days. Compared with the polluted river, TN and TP were removed about 28% and 47% by the AAFW system, respectively. The biomass of phytoplankton decrease from 6.33 mg⋅l-1<sup></sup> to 1.48 mg⋅l-1</sup><sup></sup> and the percentage of cyanobacteria decrease from 43.93% to 2.36%, the biomass of Crustacean zooplankton increase from 0.34 mg⋅l-1</sup></sup><sup></sup> to 1.53 mg⋅l-1</sup></sup><sup></sup> and the percentage of D. pulex increase from 19.19% to 57.62%. Our results indicated that the AAFW system not only is an efficient, flexible system for reducing nutrient levels in tributary rivers, but also has an ability to control the cyanobacteria bloom and rebuilding the aquatic ecosystem from the polluted river water.展开更多

This project creates a fully-functional and se- cure online user system, in which the accounts of the user system are stored in a MySQL database. Over the duration of this project, it is found that the PHP and MySQL programming languages are able to be employed for entertainment purposes, and they are both very effective in the field of entertainment. This project is meant to broaden the horizons of aspiring programmers in order to give them a glimpse into a possibility of using these programming languages in a scope that is commonly broached by game developers, but not programmers in the usual case.展开更多
