Organic Wastewater

This chemical synthesis-based pharmaceutical wastewater is treated by the process of hybrid hydrolysis acidification technique (HHAT) with anaerobic-low DO condition and the hybrid aerobic bio-technology consisted of alternate-flow biological reactor (ABR) and two-way-flow biological aerated filter (TBAF). The micro aerobic technology was employed in the HHAT and showed its advantages in refractory organic wastewater treatment. The largest plant in pharmaceutical wastewater treatment at home was built. The practice shows that the organics can be greatly removed and the effluent can reach the First Grade Discharge Standard which can be reclaimed with advanced treatment. The performance indicates that the combined bio-technologies are stable in pharmaceutical wastewater treatment.

This unbiodegradable pharmaceutical wastewater is treated by the process of hybrid hydrolysis acidification technique (HHAT) with anaerobic-low DO condition and the hybrid aerobic bio-technology consisted of alternate-flow biological reactor (ABR) and two-way-flow biological aerated filter (TBAF). The largest plant in pharmaceutical wastewater treatment at home was built.

Textile Wastewater Treatment

A combined process of biological wriggle bed and ozone biological aerated filter was utilized to treat textile wastewater. Results showed that COD removal efficiency was almost 90.4%. The average effluent COD was 85.87 mg/L. The effluent colority was 64-32 times. This study indicated that the combined process is potentially useful for treating textile wastewater.

Second Use

In order to effectively resolve pollution issue of water quenched slag and its comprehensive use or second use of materials, the water quenched slag filter material is developed using water quenched slag with the addition of adhesion-increasing agent and porogen by commingle, pelletizing and curing. Experimental results indicate that water quenched slag filter material is used as filter medium in biological aerated filter for wastewater treatment,and the removal rate of COD, NH3-N comes up to 84.62%,90.20% respectively. The filter material is much more predominant and possesses a much wider application prospect in the treatment of wastewate.
