摘要:Landfill leachate containing wastewater from a sea-based type solid waste disposal site is quite large relative to that from a land-based landfill site, because the amount of waste water to be treated corresponds to that of solid waste dumped into seawater. In order to perform wastewater treatment effectively, planned reclamation is required to adequately maintain the water quality of the pretreatment pond. In this report, the influence of leachate from waste reclamation on water quality and particularly on microbial activity in relation to nitrogen processing is examined, and intermittent reclamation is found to be effective for controlling water quality of the pretreatment pond.
