Problems solved by technology

[0002] In the petroleum industry, a lot of wastewater will be produced, which not only contains organic harmful substances such as phenol, benzene, pyridine, indole and quinoline, some of the existing treatment methods use biological treatment methods, but the oxygen demand and The chroma is still very high. The most commonly used adsorbent for wastewater treatment by adsorption is activated carbon, which requires high regeneration costs and is inconvenient to use. The adsorption function, and has a better decolorization function, but the existing adsorption resins can not adsorb ammonia nitrogen organic matter well, such as pyridine, etc., and there are many ammonia nitrogen residues

Abstract

The invention discloses special adsorption resin for liquefied petroleum wastewater treatment, and relates to the technical field of adsorption resin. The special adsorption resin is characterized by comprising the following components in parts by weight: 40-55 parts of styrene, 40-55 parts of divinylbenzene, 25-35 parts of a cross-linking agent, 50-70 parts of dimethylethanolamine, 10-20 parts of zinc chloride, 10-20 parts of tert-butylamine, 30-50 parts of a pore-foaming agent, 2-4 parts of a deoxidant, 10-20 parts of zeolite, 10-20 parts of gelatin and 5-8 parts of activated silicon dioxide. The special adsorption resin is good in adsorption effect, good in adsorption property, convenient to regenerate, and relatively good in adsorption property for ammonia nitrogen organisms, particularly for pyridine in waste petroleum liquids.

Description

Technical field: [0001] The invention relates to the technical field of adsorption resins, in particular to a special adsorption resin for liquefied petroleum wastewater treatment. Background technique: [0002] In the petroleum industry, a lot of wastewater will be produced, which not only contains organic harmful substances such as phenol, benzene, pyridine, indole and quinoline, some of the existing treatment methods use biological treatment methods, but the oxygen demand and The chroma is still very high. The most commonly used adsorbent for wastewater treatment by adsorption is activated carbon, which requires high regeneration costs and is inconvenient to use. It has good adsorption function and good decolorization function, but the existing adsorption resins cannot adsorb ammonia nitrogen organic matter well, such as pyridine, etc., and there are many ammonia nitrogen residues. Invention content: [0003] The technical problem to be solved by the present invention ...
