Embodiment 1

[0035] This example provides a preparation method for waste gas and wastewater treatment agent. Weigh 1g of indium vanadate, 1g of lanthanum cobaltate, and 0.1g of citric acid in a beaker, add 100mL of distilled water to the beaker and stir thoroughly, then add 1.5 Put 5mL of wt% PVP and 15g of carbon-based carrier into a beaker for heating in a water bath and stir with a stirrer for 1h to make the solution in the beaker heated evenly. The temperature of the water bath heating is 100°C. After the various substances were dispersed, they were uniformly mixed, and then slowly added 2.5 mol / L NaOH solution to the beaker while stirring to adjust the pH of the solution to 10 and cooled to room temperature.

[0036] Among them, both indium vanadate and lanthanum cobaltate are photocatalysts. On the one hand, they can produce strong oxidizing substances under light irradiation to decompose organic compounds, some inorganic compounds, bacteria and viruses, etc. On the other hand, they c...

Embodiment 2

[0046] This example provides a preparation method for waste gas and wastewater treatment agent. Weigh 1g of indium vanadate, 1g of lanthanum cobaltate, and 0.075g of citric acid in a beaker, add 100mL of distilled water into the beaker and stir thoroughly, then add 1.25g of distilled water into the beaker. Put 5mL of wt% PVP and 12.5g of carbon-based carrier into a beaker for heating in a water bath and stir with a stirrer for 1h to make the solution in the beaker heated evenly. The temperature of the water bath heating is 100°C. The various substances in the mixture were dispersed and mixed evenly, then slowly added 2.25 mol / L NaOH solution to the beaker while stirring to adjust the pH of the solution to 9.5 and cooled to room temperature.

[0047] Among them, both indium vanadate and lanthanum cobaltate are photocatalysts. On the one hand, they can produce strong oxidizing substances under light irradiation to decompose organic compounds, some inorganic compounds, bacteria an...

Embodiment 3

[0057] This example provides a preparation method for waste gas and wastewater treatment agent. Weigh 1g indium vanadate, 1g lanthanum cobaltate and 0.05g citric acid in a beaker, add 100mL distilled water to the beaker and stir fully, then add 1.0 Put 5mL of wt% PVP and 10g of carbon-based carrier into a beaker for heating in a water bath and stir with a stirrer for 1h to make the solution in the beaker heated evenly. The temperature of the water bath heating is 100°C. After the various substances were dispersed and mixed evenly, then slowly add 2 mol / L NaOH solution to the beaker while stirring to adjust the pH of the solution to 9 and cool to room temperature.

[0058] Among them, both indium vanadate and lanthanum cobaltate are photocatalysts. On the one hand, they can produce strong oxidizing substances under light irradiation to decompose organic compounds, some inorganic compounds, bacteria and viruses, etc. On the other hand, they can be used in daily life , the photoc...

Abstract

The invention discloses a preparation method of a waste gas and wastewater treatment agent, and the method comprises the following steps of: preparing a mixture of indium vanadate particles, lanthanumcobaltate particles and citric acid, and adding distilled water into the mixture to obtain a mixed solution I; adding polyvinylpyrrolidone and carbon-based carrier powder, and adjusting the PH valueto obtain a mixed solution II; adding zinc hydroxide particles and ferric hydroxide particles, and then adding EDTA to obtain a mixed solution III; and sequentially carrying out primary drying, centrifugation, secondary drying, washing, tertiary drying and grinding on the mixed solution III to obtain the product waste gas and wastewater treatment agent. The treatment agent disclosed by the invention can be used for treating both wastewater and waste gas, and the waste gas and the wastewater do not need to be classified when the waste gas and the wastewater are treated in industrial production;the workload of environmental protection workers is reduced, the treatment process is simplified, and the waste gas and wastewater treatment agent can be repeatedly used and is high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental pollutant treatment, and in particular relates to a preparation method and application of a waste gas and wastewater treatment agent. Background technique [0002] With the increasing industrial production, more and more attention is paid to environmental pollution, and air and water environmental pollution are even more related to the national economy and people's livelihood. The country is also paying more and more attention to the prevention and control measures of air and water pollution. The traditional treatment process is costly and complicated, and is accompanied by the possibility of secondary pollution. [0003] In addition to containing heavy metals that affect human health in wastewater, with the development of industry, highly toxic pollutants such as tetracycline and COD in wastewater also have many adverse effects on human health and living environment. Harmful compounds such...
