Abstract

Abstract: In order to remove and recover nitrogen and phosphorus of water from soil surface runoff, the combination method of cultivation and harvesting of microalgae was used in this research. Microalgae was cultured in the leachate of soil which was collected from vegetable greenhouse; culture solution was sampled and detected at different intervals. The results showed that leachate contained nutrients which could meet the needs of algal growth, the algal density increased in line with increase of culture time; pH of culture solution was alkaline and increased fast in the first 5 days; total and soluble phosphorus, total nitrogen and nitrate decreased fast in the first 5 days which showed assimilation of microalgae could remove phosphorus and nitrogen in the leachate.
