Earthworm effects on biosolids characteristics in sludge treatment wetlands

Popis výsledku v původním jazyce

s an ecological sludge treatment technology, sludge treatment wetlands (STWs) have the advantages of low investment and low energy consumption, have attracted more and more attention around the world. However, the role of earthworm on biosolids characteristics in STWs is not well known. In the present study, six STWs with two plant species (Phragmites australis, Typha angustifolia) and earthworm addition were investigated to evaluate their effects on sludge characteristics. Furthermore, feasibility for sludge land application after STWs was assessed. The results showed that the best sludge dewatering (total solids 38,3% during the feeding period) and stabilization condition (volatile solids to total solids 21,1%, dehydrogenase activity 0,65 g (TPF-tetrazole red formazan)/g (sludge) after two months of rest period) were determined in the earthworm assistant STWs planted with P. australis. The rapidly available phosphorus and available potassium contents in sludge were increased by the earthworm additi
