Abstract

The invention relates to an ammonia recovery unit based on a microbial fuel cell, and relates to an ammonia recovery unit, which aims at solving the technical problems in the conventional waste water treatment process that the ammonia and phosphorus treatment cost is high and the energy consumption is high due to the existence of the urine. The ammonia recovery unit based on the microbial fuel cell consists of an organic glass cavity, a graphite carbon brush anode, a resistor, a sealing rubber plug, a first sealing rubber plug with a Luer taper, a data acquisition system, a circuit, a carbon cloth air cathode, an air pump capable of controlling the flow rate, an absorption bottle with dilute sulfuric acid, a washing bottle, a second sealing rubber plug with a Luer taper, a third rubber plug with a Luer taper, a nitrogen bottle, a gas flowmeter, a second silicone pipeline, a first silicone pipeline, an imporous organic glass cover plate, a porous organic glass cover plate, a rubber ring and a third silicone pipeline. The invention is applied to the ammonia recovery device based on the microbial fuel cell.

Description

technical field [0001] The invention relates to an ammonia recovery device. Background technique [0002] In domestic wastewater, human urine contributes nearly 80% of nitrogen and 50% of phosphorus, while urine accounts for 1% of the volume of wastewater. In municipal wastewater treatment, excessive nutrient levels can increase the cost of the treatment process. For the denitrification process in activated sludge, the sludge residence time is relatively long, and additional electrical energy is required for sludge return and aeration. Phosphorus removal by precipitation requires the addition of ferric or aluminum chemicals. The biological denitrification process also requires a large number of reactors to create anoxic and anaerobic conditions, while providing pumping capacity for the internal circulation of wastewater. Additional costs for nutrient removal can be substantially reduced if source-separated urine is achieved. Source separation of urine can use urine as a ...
