摘要：

The purpose of this paper is to study the effectively remove organic and inorganic contaminatants in advanced treatment of coking wastewater and try to find a new efficient and inexpensive economical adsorbent project. The organic-inorganic modified Bentonite is used in the experiment as the adsorbent to find out the adsorptive capability under the different conditions of temperature, PH value, adsorptive time, and so on. The results show that Al-CTMAB MB (Aluminum Sulphate& cetyltrimethyl ammonium bromide Modified Bentonite)can reduce the ammonia nitrogen and COD in coking wastewater in the experiment with the dosage of 50g/L, shock for 30 min and PH value is 9 for the best project.
