Problems solved by technology

[0004] Printing and dyeing wastewater has complex sources and pollutant components, and has the characteristics of large water volume, high content of organic pollutants, deep chroma, high alkalinity, and rapid water quality changes. The direction of chemical and anti-biochemical development has increased the difficulty of treatment of printing and dyeing wastewater
After the dye wastewater enters the environmental water body, on the one hand, it will reduce the light transmittance of the water body and hinder the photosynthesis of aquatic plants, thereby affecting the stability of the water body ecosystem. On the other hand, dyes, additives and some intermediate products such as aromatic amines etc., all have strong toxicity and carcinogenic effects, and cause adverse effects on the ecological environment

Embodiment 1

[0039] Embodiment 1 A kind of modified zeolite and its preparation method and application

[0040] (1) Preparation method

[0041] 1) Artificial zeolite sample pretreatment: put the artificial zeolite sample in 400ml of distilled water, add 1-2 drops of dilute hydrochloric acid and shake it to neutralize the residual alkaline substances in the pores of the zeolite, wash it repeatedly until it is neutral, and then filter it. Tumble dry low.

[0042] 2) Mix HDTMA and deionized water at a ratio of 1:6 (m:m), and prepare an organic modification solution after ultrasonic stirring.

[0043] 3) Add artificial zeolite samples to the organic modification solution, the mass ratio of HDTMA to zeolite is 1:10, 1:20, 1:40, 1:60 respectively, after mixing, shake at room temperature for 30 hours, and wash repeatedly with distilled water to neutral, filter and separate to obtain a filter cake, and dry it at 60°C to obtain an organically modified zeolite.

Abstract

The invention relates to a preparation method and application of modified zeolite. The preparation method includes: adding a surfactant into deionized water to obtain an organic modified solution, with the surfactant and deionized water being in a mass ratio of 1:3-1:6; adding zeolite into the organic modified solution, with the surfactant and zeolite being in a mass ratio of 1:10-1:60, mixing the substances uniformly, then carrying out concussion reaction for 20-32h, performing filtering and low temperature drying, thus obtaining an organic modified zeolite product. Also, inorganic metal salt titanium sulfate can be added to conduct further compound modification. The composite modified zeolite prepared by the method provided by the invention shows good adsorption capacity to both copper ions and dye solutions.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a method for removing heavy metal copper ions and organic dye pollutants in sewage by using modified zeolite. Background technique [0002] The pollution of heavy metal ions caused by industrial sewage discharge is a worldwide environmental protection problem. Heavy metal ions such as Sb, Cr, Cu, Pb, Cd, Hg will cause harm to human health and the environment. Copper ions mainly come from industrial wastewater in electroplating, metal processing and other industries, and the enrichment of copper ions is often found near mines, landfills and waste disposal sites. [0003] Copper ions can cause skin itching and keratin of hands and feet in light cases, and cause gastrointestinal discomfort and liver and kidney discomfort in severe cases. People who are often exposed to high concentrations of copper ions are also at risk of liver cancer. The World Health Organization (WHO)...
