Problems solved by technology

[0004] However, the common FeC reaction tank for coking wastewater treatment has poor corrosion resistance (FeC reaction is carried out under acidic conditions, and FeC reaction has electrolytic corrosion), immersion reaction, limited reaction speed, and coking wastewater reaction product is viscous and easy to precipitate. The sediment is not easy to be removed in time, resulting in the disadvantages that the FeC packing is easy to block, harden and fail, and the FeC packing is not easy to replace

Embodiment 1

[0027] The three-phase FeC reaction device for high-concentration coking wastewater treatment of the present invention consists of a tower body 1, a spray water distributor 2, a float valve tray 3, an FeC filler 4, an aeration fan 5, an air flow redistributor 6, a folding It is composed of flow dehydrator 7, cyclone dehydrator 8, elastic damper 9, automatic discharge manhole 10, liquid discharge pipe 11 and liquid redistributor 12.

[0028] The tower body 1 is a vertical tower body, and the tower body 1 is lined with low calcium magnesium rubber to solve the corrosion problem. The top of the tower body 1 is provided with a spray water distributor 2, which is connected to the spray water inlet. Preferably: the spray water distributor 2 adopts a titanium alloy gull-wing wire-wound pipe water distributor (titanium alloy The cross section of the wire is gull wing shape). The spray water distributor 2 is installed in the tower 1 through an elastic damper 9.

[0029] At least one layer...

Abstract

The invention discloses a three-phase FeC reaction device for treating high-concentration coking wastewater. The three-phase FeC reaction device comprises a tower body, a spraying water distributor isarranged at the top of the tower body; the spraying water distributor is connected with the spraying water inlet; at least one layer of floating valve tower tray is arranged below the spraying waterdistributor in the tower body; the float valve tower tray is filled with FeC filler, an air inlet is formed below the float valve tower tray at the lowest layer, the air inlet is connected with an aeration fan, an airflow redistributor is also arranged on the air inlet, a gas discharge port and a liquid discharge pipe are respectively arranged at the tower top and the tower bottom of the tower body, and a dehydrator is arranged on the gas discharge port. The three-phase FeC reaction device for high-concentration coking wastewater treatment is reasonable in design, small in occupied area, highin reaction efficiency, good in treatment effect, resistant to corrosion and high in durability, and filler is not caked.

Description

Technical field [0001] The invention relates to a three-phase FeC reaction device used for the treatment of high-concentration coking wastewater, belonging to the field of wastewater treatment equipment. Background technique [0002] In the treatment of high-concentration coking wastewater, the focus is on the need to break the benzene ring and chromogenic substances of the benzene series pollutants in the coking wastewater. [0003] In recent years, FeC reaction tanks have been adopted at home and abroad. The FeC reaction can effectively break the benzene ring and color-producing substances, so that the COD / COD value of the coking wastewater can be significantly increased while the coking wastewater is decolorized, so as to successfully treat high-concentration coking. Waste water provides prerequisites. [0004] However, the ordinary FeC reaction tank for treating coking wastewater has poor corrosion resistance (FeC reaction is carried out under acidic conditions, and the FeC reac...
