Embodiment 1

[0029] Proportioning (percentage by weight):

[0030]

[0031]

[0032] Preparation method: First, the raw materials of each component are pulverized and ball-milled to 10-micron powder, then uniformly mixed according to the weight percentage of each component, and finally made into granules. After granulation, it is sintered at a temperature of 600° C. to form spherical particles with a diameter of 2 mm.

[0033] Usage method: Take 10 grams of spherical particles and add 30 ml of waste water from acrylic fiber factory, and stir for 30 minutes. The main component of this wastewater that needs to be degraded is acrylonitrile compound. The wastewater before and after treatment is measured with a COD measuring instrument. The results show that the COD value of the wastewater from the acrylic fiber factory is reduced from 1280 to 384 after being treated with the wastewater treatment filler filler of the present invention. The degradation rate was 70%.

Embodiment 2

[0035] Proportioning (percentage by weight):

[0036]

[0037] The preparation method: the raw materials of each component are pulverized and ball-milled to 80 nanometer powder, and then uniformly mixed according to the weight percentage of each component, and finally made into granules. After granulation, it was sintered at a temperature of 800° C. to form spherical particles with a diameter of 3 mm.

[0038] Usage method: Take 10 grams of spherical particles and add it to 30 ml of erythromycin pharmaceutical wastewater, and stir for 30 minutes. The main component that needs to be degraded in the erythromycin pharmaceutical wastewater is a heterocyclic compound. The COD measuring instrument is used to measure the wastewater before and after the treatment. The results show that the COD value of the erythromycin pharmaceutical wastewater after being treated with the waste water treatment filler of the present invention is by 3200 is reduced to 1024, and the degradation rate...

Embodiment 3

[0040] Proportioning (percentage by weight):

[0041]

[0042] The preparation method: the raw materials of each component are pulverized and ball-milled to 50-micron powder, and then uniformly mixed according to the weight percentage of each component, and finally made into granules. After granulation, it is cold-pressed into a cylindrical shape with a diameter of 2 cm and a height of 5 cm.

[0043] How to use: Take 1 kg of waste water treatment filler and put it into the pool, add 10 kg of coking waste water, and aerate for 30 minutes. The main components that need to be degraded in the coking wastewater are organic nitrogen compounds and benzene ring compounds. The COD measuring instrument is used to measure the wastewater before and after the treatment. The results show that the COD value of the coking wastewater after being treated with the waste water treatment filler filler of the present invention is changed from 4200 to 4200. Reduced to 840, the degradation rate w...

Abstract

The invention provides a wastewater treatment filling material and a preparation method thereof. The wastewater treatment filling material comprises the following component raw materials by weight percent: 20-70% of iron powder, 2-15% of copper powder, 3-10% of bamboo charcoal powder, 2-15% of kaolin, 2-15% of magnesite powder and 10%-30% of zeolite powder. The preparation method comprises the following steps: respectively smashing and carrying out ball-milling on the component raw materials; then mixing and granulating to form a granular mixture; and finally, preparing a granular filling material by high-temperature sintering or cold pressing. Compared with the prior art, the wastewater treatment filling material prepared by the method provided by the invention has the characteristics that reaction rate is high, wastewater treatment time only needs from several minutes to tens of minutes; treatment amount is large; coagulation effect is good, COD (chemical oxygen demand) removal rateis high, and removal of chroma is better; service life is long, and cost is low; the range of acting on organic pollutants is wide; and operation and management are convenient, and passivation, channeling and wastes are not generated.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a filler for wastewater treatment and a preparation method thereof. Background technique [0002] In the 1970s, Soviet researchers first mixed iron filings and coke into micro-electrolytic fillers for the treatment of printing and dyeing wastewater. This technology was introduced into my country in the 1980s. In the past 30 years, due to its simple process, low treatment cost, and good decolorization effect, it has been applied to wastewater treatment in the fields of printing and dyeing, chemical industry, electroplating, pharmaceuticals, and oil fields. Especially for the treatment of wastewater with high salinity, high COD and high chroma, it has obvious advantages over other processes. [0003] However, there are many problems in the traditional iron-carbon micro-electrolysis technology: For the traditional iron-carbon micro-electrolysis technology, the iron-carb...
