activated sludge with zeolite addition的用法和样例：
- The method of SBR activated sludge with salt-resistant organic degradation bacteria is adopted to treat produced wastewater with high content of chlorine.
- The results showed that the removal rate of formaldehyde by activated sludge increased with aerating time.
- In addition,the removal effectiveness of Sulphide,Tannin and Chromiun in a activated sludge system is also examined.
- In zeolite-biology-union adsorption and regeneration process, the zeolite adsorbed NH4(superscript +) is regenerated by the effect of both cation and nitration of activated sludge.
