Problems solved by technology

For example, a method for treating textile printing and dyeing wastewater using a coal-water slurry production process (Chinese patent application 200710026686, notification number CN100486917C), an environmentally friendly coal-water slurry and its preparation method (application number: 200810079340.2, notification number: CN 101440317A), a Straw pulp papermaking black liquor coal-water slurry dispersant and its preparation method (Chinese patent application 200810029825.0, announcement number CN101322927A), etc., using this type of technology to treat wastewater not only reduces the cost of coal-water slurry, but also solves the problem of wastewater discharge polluting the environment , but so far it has not been realized to use chemical wastewater to prepare CWS additives

Abstract

The invention discloses a method for treating wastewater of a rubber antioxidant (RD) production device, which is used for preparing active ingredients (water and an additive) of coal water slurry by synthesizing a polymer surfactant and adding the polymer surfactant into wastewater to prevent environmental pollution caused by the discharge of wastewater of the RD production device and realize reutilization of the of wastewater of the RD production device. The method comprises the following steps of: weighing 2-10 parts by mass of polystyrene, adding into 20-60 parts by mass of concentrated sulfuric acid serving as a sulfonating agent, and adding 0.01-0.1 part of silver sulfate; raising the temperature to 80-98 DEG C, and reacting under the stirring condition for 3-5 hours to obtain polystyrolsulfon acid serving as a reaction product; and adding the reaction product into 400-1,000 parts of wastewater of the RD production device, and adjusting the pH to 7 with sodium hydroxide to obtain a sodium polystyrene sulfonate solution serving as a coal water slurry additive.

Description

technical field [0001] The present invention relates to a waste water treatment process, specifically a method for treating waste water from a rubber antioxidant RD production plant, especially a method for preparing water coal by synthesizing polymer surfactants and adding such polymer surfactants to waste water The slurry additive technology is a method of preparing coal-water slurry by using the waste water from the production plant of rubber antioxidant RD. Background technique [0002] As one of the traditional pillar industries in my country, the chemical industry produces chemical raw materials and products that are widely used in many fields such as electronics, medicine and pesticides.
