Problems solved by technology

However, due to the use of proton exchange membranes or salt bridges, it not only increases the difficulty and cost of the construction of the BEC system, but also limits the construction scale of the BEC system, making it difficult to apply to engineering practice.

Embodiment Construction

[0022] see figure 1 and figure 2 In this embodiment, the anode 3 submerged in the water and evenly distributed is set in the aeration tank 1, the anode 3 is fixed by the anchor bar 6, and the anode 3 is connected to the cathode 2 floating on the surface of the water body through the wire 4. A resistor 5 is arranged in series on the wire 4 .

[0023] The anode 3 is made of conductive materials such as carbon cloth, stainless steel fiber, stainless steel wire mesh or bagged graphite particles into three-dimensional shapes such as porous and multi-layer to form a large specific surface area. 6 to be fixed to prevent the anode from drifting in the aeration tank 1 or hinder the normal operation of the aerator located at the bottom of the aeration tank, the anchor spindle 6 is a plastic part or a metal part covered with an insulating material;

[0024] Such as figure 2 As shown, the cathode 2 floating on the surface of the water body is kept on the interface between the water b...

Abstract

The invention discloses a bio-electrochemical enhanced waste water treatment device, which is characterized in that: anodes which are soaked in water and are uniformly distributed are fixedly arranged in an aeration basin; the anodes are connected with cathodes which float on the surface of a water body through leads; and a resistor is connected in series to the leads. In the treatment device, electrochemical and biochemical treatment technologies are integrated, molecular oxygen in the air can be directly utilized, and aeration in the biological treatment process of waste water is eliminated or reduced, so that the treatment device has the advantages of good waste water treatment effect, low energy consumption, long electrode service life and small investment.

Description

technical field [0001] The invention relates to a waste water treatment device, more specifically a bioelectrochemical enhanced waste water treatment device. Background technique [0002] Aeration tanks and oxidation ditch are currently the most widely used wastewater biological treatment technologies. Under the condition of continuous oxygen supply to aeration equipment, aerobic and facultative microorganisms degrade complex organic compounds into simple compounds, and the final product is carbon dioxide, thereby Reduce COD and BOD concentrations in wastewater. The electrons produced during the biodegradation process reduce the dissolved oxygen in the water to produce water. The dissolved oxygen in wastewater comes from the air introduced into the water by the aeration equipment, and a large amount of energy is consumed in the aeration process. According to statistics, according to the quality of wastewater, the energy consumption of aeration devices accounts for 30% to 7...
