| Abstract |
The aim of this study was to assess the potential of vermifiltration combined with biochar to treat domestic wastewater
contaminated with MPs using Eisenia foetida earthworm. The study experiments were conducted at the Department of Soil
Science and Environment, Faculty of Agriculture, Khon Kaen University, Thailand with a model experiment completely
randomized design: CRD 4 treatment 4 replications ( geofilter, vermifilter, geofilter with biochar and vermifilter with
biochar) and using samples of domestic wastewater from wastewater treatment plant at Khon Kaen University. The result
showed that using vermifiltration combined with biochar could reduce the biological oxygen demand (BOD), chemical
oxygen demand (COD), total suspended solids (TSS) in domestic wastewater treatment highest followed by vermifilter
with biochar, vermifiltrater, geofilter with biochar and geofilter, respectively. The results demonstrated the percentage
removal of BOD was 93.95±8.08%, n = 8, COD (91.18±11.18%, n = 8), TDS (84.92±14.40%, n = 8) but Phosphate, Nitrate
were increased. Moreover, the amount of microplastic in wastewater in effluent was decreased compared with influent by
up to 70-90% in all treatment. After 8 weeks of the experiment, the most common is the shape of the fibers and fragment
(84.85 and 15.15% respectively) Therefore, the farmer could produce vermiwash as the biofertilizer for agricultural
production and reduce the cost of using chemical fertilizer. Using vermifiltration for wastewater treatment in domestic
wastewater could be the eco-solution for nutrient recovery, water resource recycles and minimize pollution and efficient
wastewater treatment. There are ecologically sustainable solution for reducing the environmental impacts in developing
countries.
