Abstract：[Objective]Find a new processing technology of the sediment of the Yellow River, and develop the technology of drop irrigation and decrease its cost.[Method]Based on the absorption property of four high-per-formance"Shuimeng"inorganic adsorbents, we used beaker static test of the Yellow River with different sand content,and ensured the absorption efficiency of different adsorbents and appropriate dosage to sediment and nu-trient substance,selected the suitable type of adsorbent and the appropriate dosage of adsorbent under different sediment concentration and researched the influence of temperature on absorption property.[Result]The results showed that,in the case of low sediment concentration(2~3 kg/m3),the absorption efficiency of CS-001 was the best,its appropriate dosage was 0.04 kg/m3; In case of high sediment concentration(10~15 kg/m3)Yellow River water, the absorption efficiency of CS-005 was the best, the appropriate dosage was 0.08 kg/m3. Temperature had an impact on settling velocity of sediment,and the absorption efficiency of CS-001 was better in 20℃,set-tling velocity of sediment was faster. CS-001 could reduce COD,TN and TP of the Yellow River,it was signifi-cant to prevent blocking of microorganism in drop irrigation.[Conclusion]It is appropriate to use CS-001 adsor-bent in the treatment of drip irrigation using water from the Yellow River.
