Preparation of Sludge Activated Carbon Adsorbent and its Engineering Simulation Study to Removing Odor

Wastewater is purified in wastewater treatment plant, but this process produce a large amount of surplus sludge and odor including hydrogen sulfide, ammonia and so on. To candle water pollution, the wastewater treatment process leads to serious secondary pollution to environment. This paper mainly studied two problems. The first is using surplus sludge to prepare sludge activated carbon adsorbents. The second is using the product to remove the obnoxious gas in wastewater treatment plants. By analyzing the basic properties of surplus sludge and obnoxious gas, the surplus sludge was used to prepared activated carbon adsorbent by traditional chemical activation method. Final purpose is controlling waste by waste and achieving recycling. Meantime, the deodorization transfer process of sludge activated carbon adsorption was emulated and the adsorption capacity of the adsorbent in normal temperature was found out through the experiment. Besides, by optimizing the filling applicator of the sludge activated carbon, we obtained the operating parameter using the adsorbent to remove hydrogen sulfide and optimizing parameter of adsorbent filling applicator. Thus some reliable technology parameters can be offered for engineering application design and operating.
