Embodiment 1

[0014] Example 1 A new type of environmentally friendly refinery wastewater deodorant

[0015] Composed of the following raw materials by weight percentage:

[0016] Potassium Permanganate 56%, Activated Carbon 25%, Clay 14%, Contains Metal Ion Pt 2+ ionic liquid 5%.

[0017] Contains metal ions Pt 2+ The preparation method of the ionic liquid: at 45-55°C, put 0.1mol of chloro-acetylacetone and 0.1mol of N-methylimidazole in 50mL of acetone and react for 8 hours, and the product can be distilled under reduced pressure for 6 times to obtain the intermediate product; At 50°C, 0.03mol PbCl 2 Added to this intermediate product, and placed in 100mL methanol for 8h, after 6 times of distillation under reduced pressure to obtain the target product.

[0018] Preparation method: Potassium permanganate, activated carbon, clay and Pt containing metal ions 2+ The ionic liquid can be evenly mixed according to the proportion.

Embodiment 2

[0019] Example 2 A method of treating oil refinery wastewater

[0020] Methods as below:

[0021] Using the refinery wastewater provided by a refinery as raw material, the refinery wastewater has a stench, and the amount of sulfur-containing compounds such as mercaptans and sulfides is 920mg / L.

[0022] 1) At room temperature, according to the volume ratio of refinery wastewater to deodorant 2000:1, add 2500g of deodorant to the reaction kettle with 5t of refinery wastewater under stirring, then add 1000mL of concentrated sulfuric acid, and control the temperature at 20- 30°C, the reaction time is 12h.

[0023] The solution after the reaction was detected by ICP-AES method, and the amount of sulfur-containing compounds such as mercaptans and sulfides in the oil refinery wastewater was 18.4 mg / L, and the removal rate was over 98%. The stench of the solution after the reaction obviously disappeared.

[0024] 2) Add 2000g of calcium oxide to the reacted solution and stir to ...

Abstract

The invention relates to a novel environment-friendly refinery wastewater deodorizer and application thereof. The invention has the technical scheme that the novel environment-friendly refinery wastewater deodorizer is composed of the following raw materials in percentage by mass: 50-60 % of potassium permanganate, 20-30 % of activated carbon, 10-20 % of clay, and 2-7% of ionic liquid containing metal ion of Pt<2+>. A method which utilizes the deodorizer disclosed by the invention for treating refinery wastewater comprises the following steps of: taking the deodorizer and the refinery wastewater according to the volume ratio of the refinery wastewater to the deodorizer of 2000 : (1-3) under the room temperature, adding concentrated sulfuric acid, and controlling the temperature to be 20-30 DEG C and the reaction time to be 10-13 hours; and adding calcium oxide into a reacted solution for removing metal ions of Mn<2+> and the Pt<2+> and avoiding secondary pollution. The novel environment-friendly refinery wastewater deodorizer disclosed by the invention is simple in operation and low in cost; an organic solvent is not used in an operation process, thus obtained bottom mud is subjected to innocent treatment, can be reused, cannot cause environmental pollution and is innocuousness for the health of an operator.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a deodorant for removing the odor of oil refinery wastewater and its application. Background technique [0002] With the rapid growth of the global economy and population, the discharge of sewage is increasing, and the pollution of water bodies is also increasing. This makes many countries, including my country, face a serious shortage of water resources. At the same time, water pollution will affect human survival and health. Therefore, the control of water pollution is imminent. Sewage treatment is not just a simple treatment of sewage, but more towards the development of sewage reuse and water conservation. [0003] Oil refinery wastewater is a type of wastewater produced in the process of crude oil refining, processing, and oil washing. The stench seriously pollutes the environment and endangers human health. At present, due to the large amount of wastewater produc...
