Application of innovative irrigated cropping and soil filtration technology for wastewater reuse and treatment in China

Overview of Project

Two thirds of China’s total crop production is from irrigated lands. There is, however, increasing pressure on water supplies from the spread of urbanisation and industrialisation. There is also increasing production of wastewater, resulting in environmental pollution. Most rivers, lakes, bays and groundwater sources are showing increasing signs of severe pollution, including from organic matter, nutrients, heavy metals and other toxic chemicals. As a result water use in agriculture, fisheries and recreation is greatly limited. Reusing effluent in suitable agricultural conditions is a possibility, provided appropriate land treatment and reuse techniques are in place. The project had three main objectives:

  • to develop and field-test innovative FILTER techniques for sustainable irrigation with wastewater at a demonstration site in Shanxi Province;
  • to promote the application of FILTER technology for sustainable irrigation with wastewater in Shanxi and other Chinese provinces;
  • to develop simple integrated approaches for siting, design and operation of FILTER and related technology in China and Australia.
Key Outcomes of Project
  • Objective 1: At Yanggao County near Datong city in Shanxi province, a field site consisting of three plots was installed on a farmer’s field to evaluate the catchment-FILTER technology. The scientists studied summer, winter and groundwater components, using instrumentation to monitor wastewater and pollutant flows through the soil.
  • Objective 2: Promotion of the application of FILTER technology for sustainable irrigation with wastewater irrigation in Shanxi and other Chinese provinces was carried out by the IWHR and SIWR researchers. The IWHR researchers in collaboration with Beijing Water Resources Bureau developed and successfully field-tested an innovative FILTER-polyhouse system to combine the FILTER technology with greenhouse agriculture systems to overcome the low infiltration during winter freezing conditions in north China. The FILTER technology was also promoted at discussions with the Ministry of Science and Technology (MOST) and provincial authorities.
  • Objective 3: Simplified integrated approaches for siting, design and operation of the new FILTER and related technology in China and Australia were developed. These approaches are incorporated into the guidelines for using Land-FILTER and Catchment-FILTER systems for using wastewater in China and Australia.
