This project aims to invent the wastewater treatment machine and to studies, the performance of coliform bacteria disinfection by mixing clear coating with Nano ZnO coated on a propeller and inside the bucket. Use ultraviolet light to catalysis Nano ZnO and disinfects coliform bacteria. The activated charcoal box was used to absorb the waste gas from Hydrogen sulfide (H2S) by suck the air pass through the tube that contains activated carbon. From the measurement of water quality by measure pH, DO, hydrogen sulfide concentration and total coliform bacteria every 30 minutes for 6 times, the results showed that pH decrease to 6.82 from 4.22, DO increase to 4.02 mg /l from 2.31 mg /l, the total of coliform bacteria decreased and the concentration of hydrogen sulfide decrease after absorption. The information representing that the wastewater treatment machine can treatment wastewater contamination coliform bacteria and absorb the hydrogen sulfide.
