Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "placed on" another component, it can be set directly on the oth...

The invention relates to the technical field of sewage disposal, in particular to a high-concentration degradation-resistant wastewater treatment device and process. The treatment device comprises a pH value adjuster, a coke cooling tank, a coke tower, a condenser, a first degreaser, a stripping tower, a solid-liquid separator and a second degreaser, wastewater is discharged from a wastewater storage tank, the pH value of the wastewater is adjusted through the pH value adjuster, then the wastewater enters the coke cooling tank and is diluted with coke cooling water, and the diluted wastewateris fed into the coke tower for high-temperature decomposition treatment; steam from the coke tower is treated by the condenser, the first degreaser and the stripping tower to obtain sump oil, ammonianitrogen, sulfide and recyclable water, and decomposed wastewater from the coke tower is treated by the solid-liquid separator and the second degreaser to obtain coking powder, sump oil and recyclablewater. The wastewater treatment device has the advantages of high treatment efficiency of high-concentration degradation-resistant wastewater, short time, low equipment operation cost and low requirements on operation conditions.
Description
【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to a high-concentration refractory wastewater treatment device and a treatment process. 【Background technique】 [0002] In January 2016, about 4000m 3 High-concentration sewage is mainly the sewage produced by cleaning and passivation during the maintenance process of desulfurization, dehydration, sulfur recovery and other process equipment. Because there is no reliable disposal plan, the accident water tank TK-202 of the temporary sewage treatment plant is temporarily stored according to the company's overall planning. 2018 In May 2019, about 1,092m2 of the 4# and 5# light dirty oil tanks in the company's storage and transportation department were cleaned 3 High-concentration organic amine sewage is sent to TK-202. Because of its strong toxicity, organic amine wastewater can easily cause impact on the biochemical system and cannot enter the sewage system for treatment. ...
