Abstract

Myriophyllum aquaticum is a common plant to be used for wastewater treatment in aqueous wastewater systems, but how to deal with harvest M.aquaticum is still a real problem. Earthworms play an important role in the decomposition procession, now we selected 30 earthworms in a pot experiment to treat the M.aquaticum and sludge together. we use different volume ratios for each treatment, the result shows that: under the condition of sludge: M.aquaticum=70%:30%, earthworm reactor plant takes the highest treatment efficiency, after 30 days treatment, earthworm increased 155%, treated products volume decreased 75.6%, available NPK takes greatly increased. This study given us a new point for wetland plant and sludge co-treatment, and proves to utilize earthworm reactor is suitable for sludge and wetland plants transforming, meanwhile, after earthworm treatment for 30 days, the treated products took good quality, which can be used for organic fertilizer application.

Comment: Base on reviewers‘ comments and suggestions for our paper, we did a lot of changes, revised and improved the paper quality. We supplied the information for our experiment in the phytotron, added more date analyzing for table 2, table 3 etc,. We have also updated our references and did some other improvements for introduction and discussion part, which can be seen from the main content.
