Example Embodiment

[0049] Example 1:

[0050] A process system for removing the total organic carbon of an emulsion biochemical effluent, including a double-layer high-efficiency catalytic reaction tower, an ozone inlet, a water inlet, a distributor, a bottom catalyst layer, a supported two-element complex molecular sieve catalyst, and intermediate water Layer, top catalytic adsorbent layer, supported manganese-based activated carbon catalyst, water outlet and air outlet.

[0051] The biochemical effluent of the emulsion refers to wastewater that has been treated by anoxic and aerobic biochemical tanks. The pH of the biochemical effluent of the emulsion is 7.9, and the total organic carbon is 62 mg / L.

[0052] The biochemical effluent of the emulsion enters the double-layer high-efficiency catalytic reaction tower from the waste water inlet through a lift pump. Ozone enters the reaction tower from the double-layer high-efficiency catalytic reaction tower through the pipeline, and the water and gas fl...

Abstract

The invention relates to a method for removing the total organic carbon in emulsification liquid biochemical effluent. According to the method, emulsification liquid biochemical effluent and ozone firstly enter the bottom portion catalyst layer of a double-layer efficient catalytic reaction tower, wherein the bottom portion catalyst layer is provided with a supported binary complexing molecular sieve catalyst for removing the total organic carbon in the biochemical effluent, and the supported binary complexing molecular sieve catalyst adopts alumina carrier as a carrier and has a specific surface area of 123-155 m<2>/g; the emulsification liquid biochemical effluent and the ozone then enter a top portion catalytic adsorbent layer, wherein the top portion catalytic adsorbent layer is provided with a supported manganese-based active carbon catalyst having an active carbon particle size of 1-3 mm and soaked with a manganese nitrate solution; and the emulsification liquid biochemical effluent is discharged through a water outlet, and gas is discharged through the gas outlet on the upper portion of the double-layer efficient catalytic reaction tower. With the technical scheme of the present invention, the environmental pollution can be reduced, and the increasingly stringent environmental protection laws and regulations can be positively replied.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a method and a device for efficiently removing total organic carbon in emulsified liquid biochemical effluent water. Background technique [0002] As my country's basic industry, the iron and steel industry has developed rapidly since the reform and opening up, and has been in a high-speed development stage in recent years. However, the iron and steel industry is an industry with high energy consumption, high resources and high pollution, and its water consumption is huge, accounting for about 14% of the national industrial water consumption. [0003] The emulsion mainly contains organic oil and surfactant, which is prepared by diluting emulsified oil with water and adding emulsifier as needed. Emulsion wastewater is characterized by a wide variety, high concentrations of total organic carbon and oil content, and difficult wastewater treatment. [0004] The ...
