Treat Shrimp Wastewater with Compound Photosynthetic Bacteria

Shrimp wastewater was studied by using photosynthetic bacteria sludge method. The results indicated that this method got better effects than single sludge or only photosynthetic bacteria treatment. The removal of the CODcr could reach 63%, the removal of the NH₃-N could reach 92.5 %. Compared with conventional methods, it had easier operation, lower cost; and need not deal with the problem of sludge. Another advantage of this method was that it could solve the problem of photosynthetic bacteria losing. Based on the experiment a feasible technical method was suggested by the authors.
