Abstract:
The treatment of organic sewage is studied by using p hotosy nthetic bacter ia ( PSB) in this project. pH, CODCr , BOD5 and PSB quant ity during the treatment has been illustr ated. After tr eatment, the CODCr and BOD5 removal ratio of t he sew age coming from ho tel sewage, residential quarter sew age and w astew ater of bean pr oduct plant is 70. 3%, 69. 1% and 82. 2% ( CODCr) ; 87. 2%, 91. 1% and 92. 9% ( BOD5) r espectiv ely. The PSB quantity r eaches 5. 9× 108/ mL, 4. 2 × 108/ mL and 3. 0 ×109 / mL respectively. Its outflow pH is 8. 0, 7. 6 and 7. 4. This method has a lot of advantag es: low cost, simple process and w ithout secondary pollution.
