Problems solved by technology

However, this will cause the separated water to contain high minerals such as calcium salts and magnesium salts, which are easy to crystallize and form scale, which will reduce the service life of the equipment
At the same time, oily wastewater contains hydrogen sulfide and carbon dioxide, which will corrode the pipes and pumps of the treatment system, easily cause scaling, and cause bacterial conjunctiva

Embodiment 1

[0021] Put 10 parts, 15 parts and 3 parts of stearic acid, diethylenetriamine, and boric acid into the preset reaction kettle according to the mass parts respectively, fill with nitrogen, stir, and raise the temperature to 115°C until no water comes out, and the completion Amidation reaction; continue to heat up to 200°C to complete the cyclization reaction; cool down to 40°C, add 15 parts of benzyl chloride to complete the quaternization reaction.

[0022] (1) Put imidazoline quaternary ammonium salt, peracetic acid, polyoxyethylene fatty acid ester, and alum into the reaction kettle in order of 1 part, 20 parts, 10 parts and 1 part by mass respectively, and put them into the reaction kettle Fill with nitrogen and start stirring;

[0023] (2) Raise the temperature to 60°C and stir evenly until all raw materials are completely dissolved to obtain a new sewage treatment agent.

Embodiment 2

[0025] Compared with Example 1, stearic acid, diethylenetriamine, boric acid, and benzyl chloride required for the preparation of imidazoline quaternary ammonium salts in this example are respectively 12 parts, 19 parts, 3.5 parts, and 20 parts by mass. share. The amidation reaction temperature is 125°C. The temperature of the cyclization reaction is 225°C. The temperature of the quaternization reaction is 45°C. The imidazoline quaternary ammonium salt, peracetic acid, polyoxyethylene fatty acid ester and alum required for the preparation of the novel sewage treatment agent are 6 parts, 24 parts, 15 parts and 4 parts by mass respectively. The temperature rises to 75°C when preparing the new sewage treatment agent. The rest of the process and equipment used are the same as those in Embodiment 1, and will not be described again.

Embodiment 3

[0027] Compared with Example 1, stearic acid, diethylenetriamine, boric acid, and benzyl chloride required for the preparation of imidazoline quaternary ammonium salts in this example are respectively 15 parts, 25 parts, 5 parts, and 30 parts by mass. share. The amidation reaction temperature is 145°C. The cyclization reaction temperature is 240°C. The temperature of the quaternization reaction is 60°C. The imidazoline quaternary ammonium salt, peracetic acid, polyoxyethylene fatty acid ester, and alum required for preparing the novel sewage treatment agent are respectively 10, 30, 25, and 5 parts by mass. The temperature rises to 100°C when preparing the new sewage treatment agent. The rest of the process and equipment used are the same as those in Embodiment 1, and will not be described again.

Abstract

The invention discloses a sewage treating agent and a production process thereof, and belongs to the technical field of oil-containing wastewater treatment. The sewage treating agent is characterized by being prepared by mixing imidazoline quaternary ammonium salt, peracetic acid, polyoxyethylene aliphatate and alums which serve as raw materials and performing complex reaction. The novel sewage treating agent is combined with calcium ions and magnesium ions, so that the flocculation speed can be increased, the oil drops and suspended matter in the oil-containing wastewater are separated, dirtgenerated by crystallization of calcium salt and magnesium salt can be removed under the solubilizing and dispersing action and the scaling problem can be solved radically. Meanwhile, the treating agent can remove hydrogen sulfide and carbon dioxide from water, and cannot corrode a pipeline and a mechanical pump of a treating system, so that the phenomenon of scaling and film forming of bacteriumare avoided in the treatment process. Water in the oil-containing wastewater which is treated by the novel sewage treating agent can be recycled.

Description

technical field [0001] The invention belongs to the technical field of oily wastewater treatment, and in particular relates to a sewage treatment agent and a production process thereof. Background technique [0002] The oily wastewater in the petroleum industry mainly comes from the processes of petroleum exploration, petroleum refining and petrochemical production. With the development of the petroleum industry, more and more oily wastewater is produced, and most manufacturers choose to bury it deep in the soil or discharge it into rivers through urban channels. In this way, it not only causes waste of resources, but also brings great pollution to the environment. If oily wastewater enters the soil, it will use the soil voids to form an oil film, resulting in clogging, resulting in the infiltration of air, water and fertilizers into the soil, destroying the soil structure, which is not conducive to the growth of crops, and in severe cases will lead to the death of crops. ...
