New design of outer loop bioreactor for liquid wastewater treatment

摘要

A novel biological treatment process is very effective in the treatment of various soluble and colloidal pollutants in agricultural, industrial and urban liquid emissions, and the cost is low. The invention includes an industrial device which allows biodegradation of organic pollutant fillers. In the case of liquid to liquid effluents, the technique has been successfully tested.Bioburden The treatment was carried out in the presence of microalgae. The emission from the developed outer ring gas bioreactor was controlled by continuous supply of the effluent and oxygen.This is the first time that ventilation has been used in such equipment. The invention focuses on the administration of ambient air containing a large amount of oxygen and carbon gas for biological treatment in the presence of microalgae. For the first time in this type of reactor, this transport is provided by ventilated air tickets, resulting in depression between the outside and inside of the reactor, resulting in a large amount of air flow to the inside of the equipment. Compared with other treatment technologies in similar reactors,This method is very advantageous in processing efficiency and energy consumption. Treatment of agricultural emissions tested in a 35 liter capacity facilityAccording to records, the degradation efficiency of chlordecone is 87.35%, the dechlorination rate is about 90.46%, the energy consumption is 0.8 w / kg carbon dioxide, and the treatment time is 12 hours.
