The invention discloses a double-triangular-pipe valve-controlled renewable ecological restoration system. The system comprises double-triangular-pipe valve-control adjusting units, renewable biological membrane and adsorption material coupling purification units, and stable pond plant purification and assimilation absorption units; the double-triangular-pipe valve-control adjusting units are usedfor controlling open and close of valves in double triangular pipelines, so that an ecological restoration function and a self-renewable function of the system are realized; the renewable biologicalmembrane and adsorption material coupling purification units are used for filtering out impurities in a water flow and absorbing nitrogen and phosphorus elements in water; and the stable pond plant purification and assimilation absorption units are used for treating organic pollutants and pathogens in wastewater. The renewable ecological restoration system provided by the invention has the comprehensive effects of simple structure, wide application range, renewable utilization, purification of urban slow water, and beautification of living environment.
