发明名称 Waste water treating process
摘要 Disclosed is a process for treating waste water containing high levels of organic waste products which employs a series of chambers through which the water flows with the upstream chambers promoting anaerobic digestion of the waste products and the downstream chambers promoting aerobic digestion of the waste products. The upstream chambers are charged with a sludge preferably which, because of the conditions maintained within the chamber, has an ash-like characteristic upon being dried and does not contain high levels of water included within it. It is sometimes desirable to recharge the chamber with sludge since this sludge acts as a buffer that can digest shock loads of waste products having a high chemical oxygen demand. The chambers include water circulators which stir the water within the chambers and the downstream chambers having floating on the water surface high surface area media which carries bacteria. Preferably the water flows through the downstream aerobic chamber in a carousel-like fashion.
