Abstract

The invention discloses a treatment device and a treatment method of biological diesel oil waste water. A waste water feed valve of the treatment device is arranged on a pipeline for communicating an outlet of a water tank with a low-position end of an adsorption column; a treated wastewater receiving valve is arranged on a pipeline for communicating an upper-position end of the adsorption column with an inlet of a receiving tank; a compressed air valve is arranged on a pipeline for communicating an outlet of compressed air with the upper-position end of the adsorption column; a desorption agent outlet valve is arranged on a pipeline for communicating an outlet of a desorption agent tank with the upper-position end of the adsorption column; an inlet valve of a desorption agent circulating pump is arranged on a pipeline for communicating an inlet of the desorption agent tank with an outlet of the desorption agent circulating pump; a desorption agent inlet valve is arranged on a pipeline for communicating the low-position end of the adsorption column with an inlet of the desorption agent circulating pump; the adsorption column is internally filled with a DXDA-1000 type macroporous resin. Desorption circulation of the macroporous resin in the adsorption column is formed, the structure is simple and practical, and grease adsorption and resin recycling effects are good.

Description

technical field [0001] The invention relates to biodiesel wastewater treatment equipment and a treatment method thereof. Background technique [0002] Biodiesel wastewater refers to the untreated wastewater discharged from the biodiesel production process. It has complex components and high organic content. biochemical treatment. However, biodiesel wastewater contains a certain amount of oil, and the mother liquor obtained by evaporation is a mixture of oil and glycerin, which is very difficult to separate and can only be treated by incineration, which is costly and pollutes the environment. After long-term operation of the evaporator , easy to scale, difficult to clean. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a new biodiesel wastewater treatment process that is not only economical and practical, but also can recycle the waste resources in the biodiesel wastewater and the trea...
