A joint resource recycling project between China and Germany was completed on Sunday in East China’s Qingdao city, as part of bilateral efforts for innovative research on clean water.
The recycling center, in the garden for ongoing Qingdao International Horticultural Exhibition, is capable of treating 1,500 cubic meters of domestic sewage per day from washing, cooking or toilets, said operators of the center.
The treated water will return to houses of residents through special pipes for toilet use or be used to irrigate urban plants.
The silt treatment section of the center can process 50 cubic meters of silt and kitchen garbage per day, which can produce 2,100 cubic meters of methane and 200 kilowatts of electricity for the center’s own power supply.
The project was introduced by the Qingdao municipal government in 2012. It has got technological support from Chinese and German universities or institutions during construction.
