The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality.

可持续污水灌溉工程-污水灌溉对土壤碱度和地下水水质的影响目前，负责集中收集、处理和处置废水的一些地方当局和机构定期对再生城市污水进行土地应用。经过处理的城市污水通常是用于种植硬木种植园的土地。阔叶木种植园在生产大量生物质方面非常有效，还帮助各机构抵消与高级废水处理相关的废水处理和处置费用，以去除养分。该项目将研究污水灌溉对新南威尔士州猎人谷两个阔叶树种植园土壤化学和地下水质量的影响。越来越清楚的是，大规模再利用计划，特别是涉及阔叶木种植园的计划，必须设计成可持续的，并且不会对土壤化学(不断增加的碱度)和地下水产生重大影响。该项目将为阔叶木种植园开发灌溉制度，以提高土壤生产力，并优化污染物去除和生物质生产的污水利用率。

The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality. The land application of recycled municipal effluent is now regularly practised by a number of local authorities and agencies responsible for centralised collection of wastewater, its treatment and disposal. Treated municipal effluent is often land applied and used to grow hardwood plantations. Hardwood plantations are very effective in producing large amounts of biomass and also assist agencies in off-setting wastewater treatment and disposal costs associated with advanced wastewater treatment to remove nutrients. This project will examine the effects of effluent irrigation on soil chemistry and groundwater quality at two hardwood plantations in the Hunter Valley, NSW. It is increasingly clear that large-scale reuse schemes, particularly those involving hardwood plantations, must be designed to be sustainable and have no significant impact on soil chemistry (increasing sodicity) and groundwater. This project will develop irrigation regimes for hardwood plantations which will promote soil productivity and optimize effluent application rates for pollutant removal and biomass production.\r\n\r\n
