BFT 양식장 배출수를 활용한 도시농업용 비료개발

Abstract

The objective of this study is to find a useful method of utilizing effluent water from the BFT inland water culture. Recently Sludge andeffluent water have been noted to cause water pollution. Therefore, this progressive study of recycling method will replace the use ofchemical fertilization. Effluent water from inland water culture contains many fertilization ingredients. This study used different usingmethods of fertilization. As a result, effluent water that isn't matured and diluted had positive effects on the growth of lettuce. Effluentwater of undiluted involved many mineral elements and proper pH concentration for plants growth but which are involved manyconcentrations of Na+ion. High concentrations of Na+ions are harmful for the growth of plants. This experiment did not show plantsadversely affected by Na+ions. Potentially Na+ions can cause physiological disturbances of the plant. Effluent water smells becauseeffluent waters using is need to additional pre-treatment for removal its high concentration Na+ions and bad smell.
