Problems solved by technology

[0007] Nonylphenol is more harmful to aquatic ecosystems, but at present, there is no water quality standard for nonylphenol in China, and there is no wastewater treatment technology specifically for nonylphenol. Therefore, it is urgent to provide a nonylphenol water quality standard The formulation method and the removal method of nonylphenol in water

Embodiment 1

[0044] A method for formulating a nonylphenol regional water quality standard, comprising the following steps:

[0045] S1. Collection and screening of toxicity data: collect toxicity data of species in the area, and exclude toxicity data of non-native species;

[0046] Based on the characteristics of the aquatic biota in the Taihu Lake Basin, this paper reviewed the published literature reports at home and abroad, and based on the minimum species requirement principle and toxicity data screening principle in the document "Technical Guidelines for Water Quality Benchmarking of Freshwater Aquatic Organisms" (HJ 2017-831) in China, Collect water ecotoxicological data of species in the Taihu Lake Basin, and try to select Taihu species as much as possible. Species widely distributed in Jiangsu, Zhejiang and the Yangtze River can also be regarded as Taihu species.

[0047] Specifically, it includes acute toxicity data, chronic toxicity data (reproductive toxicity, developmental tox...

Embodiment 2-5

[0091] A method for removing nonylphenol in a water body is to use a composite reagent to adsorb nonylphenol-containing water, and the composite reagent is composed of the following raw materials in parts by weight: 100-300 parts by weight of corncob biochar and gas-phase dioxide 10-50 parts of silicon, 50-100 mg of nonylphenol water per liter of the above composite reagent.

[0092] The composition and addition amount of the composite reagents in Examples 2-5 are shown in Table 6.

Abstract

The invention discloses a method for formulating a nonylphenol regional water quality standard, comprising the following steps: S1, collection and screening of toxicity data; S2, derivation of a water quality standard for protecting aquatic organisms; S3, formulation of water quality standards; S4, evaluation of water quality standards: the Evaluation of water quality standards, including: S41 Domestic and foreign nonylphenol aquatic organism water quality standards and standards: S42, Regional concentration environmental analysis: S43 Economic analysis: S44 Method and detection limit analysis: S45 Expert review. The water quality standard value for protecting aquatic organisms of the invention is reasonable and feasible, can provide appropriate protection for aquatic organisms, and is suitable for the current environmental management level in my country; also discloses a method for removing nonylphenol in water body, which can effectively remove nonylphenol in water body. Base phenol, the effluent concentration is lower than 2.8μg / L, in terms of wastewater treatment technology, it meets the daily management standard limit requirements of NP.

Description

technical field [0001] The invention belongs to the technical field of water environmental protection methods, and in particular relates to a method for formulating a nonylphenol water quality standard and a method for removing nonylphenol in a water body. Background technique [0002] Nonyl phenol (Nonyl Phenol, referred to as NP), also known as nonyl phenol, the molecular formula is C 15 H 24 O, the molecular weight is 220.24. Nonylphenol is an important fine chemical raw material and intermediate. Its appearance is colorless or light yellow liquid at room temperature, with a slight phenol odor. The relative density is 0.94 to 0.95. It is soluble in acetone, ethanol and chloroform, slightly soluble. In petroleum ether, insoluble in water. Nonylphenol is mainly used in the production of surfactants, antioxidants, textile printing and dyeing auxiliaries, lubricant additives, pesticide emulsifiers, resin modifiers, resin and rubber stabilizers and other fields. [0003] N...
