Treatment of town domestic sewage with the compounds of diatomite and coagulants(CDGC) is investigated. The results show that three types of CDGC in the optimal operating conditions have better effect on domestic sewage treatment than coagulants alone. The CODCr removal rate is above 64.0%, SS and NH3-N removals are above 88.9% and 41.0%, respectively. The effluent water quality reaches the second grade discharge standard of GB 18918-2002. The running cost is lower than other general treatment technics. Therefore, it has a wider application potential.
Key words： domestic sewage; diatomite; enhanced coagulation
