【 摘 要 】

This study focuses on the reduction of COD, BOD, TDS, TSS, cadmium, lead, arsenic, chloride, and sulphate in textile industries. Microbial presence in the wastewater can treat effectively by providing a favorable environment. Solids Retention Time (SRT) is a key functioning element that affects the AS process efficacy. The efficiency of pH, BOD, COD, TDS, TSS, cadmium, lead, arsenic, chloride, and sulphate is taken into measure. Engineering-oriented approach was adopted to treat the aforesaid parameters through the inoculation of microbes in the biological treatment process. The designed Effluent treatment plant was based on screening, equalization, neutralization, aeration/ biological reactor and biological sedimentation. Treatment proves to be more efficient by the addition of cationic and anionic polymer i.e. Coagulant and flocculant. Overall, the efficiency of the designed treatment is taken into COD, BOD, TDS, TSS, cadmium, lead, arsenic, chloride, and sulphate 86.6%, 88.59%, 63.86%, 89.25%, 94.12%, 98.36%, 50%, 33% and 41% respectively. Statistical analysis has been performed that shows Correlation is high with BOD, TDS, TSS, Cd, lead, and As except chloride. in aforesaid parameter if concentration is decreased it means COD concentration will also decreased and has directly proportional relation with each other. As a result of the designed effluent treatment plant, treated effluent is discharged that has no significant negative impacts on the environment.
