Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 and image 3 As shown, a coking wastewater degreasing treatment device includes a coking wastewater pre-filter 1 and an oil-water separator 2. The coking wastewater is first filtered through the coking wastewater pre-filter 1, and then enters the oil-water separator 2 for oil-water separation.

[0044] The structure and working principle of the coking wastewater pre-filter 1 and the oil-water separator 2 will be introduced first.

[0045] combine figure 1 and figure 2 As shown, the coking wastewater pre-filter 1 is a vertical container equipped with a complete set of control system, which mainly treats sundries such as tar and coke powder in the coking wastewater. A plurality of porous filter elements 101, a filter cloth set on the periphery of the filter element 101, a liquid outlet pipe 103...

Abstract

The invention relates to a coking wastewater oil removal treatment device and method. The device comprises a coking wastewater pre-filter and an oil-water separator, the coking wastewater pre-filter comprises a barrel, a filter element installed in the barrel, filter cloth arranged outside the filter element in a sleeving mode, a liquid outlet pipe connected with the filter element, a blowback pipe, a circulating pipe and a liquid inlet pipe connected with the barrel, a forward blowing port is formed in the barrel, a slag discharging port is formed in the bottom of the barrel, the other end ofthe circulating pipe is connected with the barrel, the oil-water separator comprises a tank body, and a rotational flow gathering and filtering cavity, a primary coarse filtration gathering cavity, aW-shaped corrugated plate cavity, a secondary fine filtration adsorption cavity and a water outlet transition cavity which are arranged in the tank body, a water inlet pipe connected with the rotational flow gathering and filtering cavity and a water outlet pipe connected with the water outlet transition cavity are arranged on the tank body, an oil collecting bag is arranged at the top of the tank body and is connected with an oil outlet pipe, and the liquid outlet pipe is connected with the water inlet pipe. The invention further relates to a method for treating coking wastewater by using the coking wastewater oil removal treatment device. The problem that coking wastewater is difficult to treat is solved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a coking wastewater degreasing treatment device and treatment method. Background technique [0002] Coking wastewater is a typical wastewater containing aromatic compounds and heterocyclic compounds. The organic pollutants are mainly phenolic compounds, accounting for more than half of the organic pollutants. In addition, there are polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen and sulfur. Cyclic compounds, etc.; inorganic pollutants are mainly hydrides, hydrogen sulfides, sulfides, ammonia salts, etc., as well as polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen, and sulfur; coking wastewater is toxic Harmful high-concentration wastewater is very difficult to treat, especially wastewater that has not been treated with dephenolization, ammonia distillation, and oil removal. The content of phenol, NH3-N, and o...
