| Abstract: |
| To explore the effects of the automated and intelligent operation of livestock breeding wastewater treatment facilities, a large-scale farm wastewater treatment facility with a daily production of 250 m3 of wastewater was investigated in this study. This wastewater treatment facility was equipped with a video surveillance system and online monitoring equipment. It was also equipped with early warning and forecasting functions to show the effect of the automated and intelligent operations. It was found that the sludge concentration, DO, and pH values were all controlled within a reasonable range of 4 000~7 000 mg·L-1, 1.5 mg·L-1(first-stage aerobic tank)and 3~5 mg·L-1 (second-stage aerobic tank), and 6.5~8.5, respectively. The concentrations of COD and ammonia nitrogen in the effluent of the two-stage AO treatment tank were all up to the standard concentrations, that was, lower than 70 mg·L-1 and 10 mg·L-1, respectively. This showed that the automated operation of the facility was stable and that the facility could effectively treat wastewater from breeding farms. Through functions such as video monitoring, online monitoring, early warning, and forecasting, the operation status of each wastewater treatment stage could be effectively monitored to detect and solve potential issues on time, thereby improving the efficiency of the facility operation and reducing the input of operators to reduce operating expenses. The actual operation results showed that implementing automation and intelligence in wastewater treatment facilities can effectively improve the overall operation and efficiency, avoid environmental risks to the greatest extent, and reduce operating costs. |
