Research on Biostimulant in Scenic Water Bioremediation

This paper investigated the improvement of water quality in polluted scenic water bioremediation by using biostimulant studied independent. The main material biochemical fulvic acid is made from agricultural wastes straw. The comparison experiments results showed that the effect of biostimulant closed to the introduction reagent in some water quality indexes, and better in some aspects else. It could be used in actual polluted scenic water bioremediation instead of the introduction reagent or partially. The cost price of the bioremediation and the biostimulant are both not high, because of the cheap main material. At the same time, the multipurpose use of agricultural wastes problem could be solved effectively. The removal rates of CODCr and TP were more than 10% higher in the samples extra added trace elements B and Mo, contrast to the samples only with biostimulant.
