Abstract
The invention discloses a preparation method of a modified volcanic cinders filler for removing heavy metals and total phosphorus in electroplating waste liquid. The modified filler carrier is volcanic cinders, and the modified volcanic cinders are prepared by adding a modifying agent in proportion and controlling two indexes of modified pH, modified temperature and the like. The filler has a good removing effect on heavy metals such as zinc, manganese, nickel and the like and total phosphorus in neutral, slightly acidic and slightly alkaline electroplating waste liquid, and provides a new idea for treating the electroplating waste liquid.
Description
Technical Field
The invention relates to a preparation technology of a modified filler in the field of sewage treatment, in particular to a preparation method of a modified volcanic cinders filler for removing heavy metals and total phosphorus in electroplating waste liquid.
Background
The traditional filler adsorbent is mainly activated carbon, is expensive, has limited effect on electroplating wastewater which is a wastewater with complex components, and limits the application of the traditional filler adsorbent to a certain extent. In recent years, people find that the physical and chemical properties of the surface of the carrier can be greatly improved by modifying the filler, the decontamination and pollutant interception capabilities of the carrier are increased, a better adsorption effect is obtained, and the quality of the effluent reaches the standard.
The volcanic cinders are slag-shaped porous light-weight framework materials formed by volcanic eruption, and have the properties of acid and alkali resistance, corrosion resistance, poor electric conductivity, good water permeability and the like. At present, the utilization of volcanic cinders in China is mainly concentrated in the field of constructional engineering, the development of high added value of the volcanic cinders is in a seriously lagged situation, and particularly, reports are few in the field of sewage treatment. The volcanic cinders are modified by a special technical means, a preparation method of the modified volcanic cinders filler for removing heavy metals and total phosphorus in the electroplating waste liquid is developed, and an economic and environment-friendly thought can be provided for the treatment of the electroplating waste water.

(1) pretreating volcanic cinders;
(2) preparing a modified medicament;
(3) adding a modifying agent, and controlling the modifying pH and the modifying temperature.
According to the technical scheme provided by the invention, the preparation method of the modified volcanic cinders filler for removing heavy metals and total phosphorus in the electroplating waste liquid provided by the invention has the advantages that volcanic cinders are soaked, cleaned and dried by pure water, and the pH and temperature indexes are controlled by adding sodium fluoride and calcium hydroxide modifiers according to a proportion to achieve the purpose of preparing the modified volcanic cinders filler. The filler has a good removing effect on zinc, manganese, nickel and other heavy metals and total phosphorus in the electroplating waste liquid.
Detailed Description
The invention is further illustrated by the following examples, but is not limited thereto.
Example 1, the procedure was as follows:
(1) putting 100g of volcanic cinders meeting the particle size requirement into a sample cup, adding pure water, stirring, standing overnight and drying;
(2) putting 3g of high-grade pure sodium fluoride and 12.5g of high-grade pure calcium hydroxide into a beaker, adding 100mL of pure water, and uniformly stirring to obtain a modifier;
(3) pouring the modifier into a sample cup, fully stirring, adding 23mL of pure water to adjust the pH value to 8.3, keeping the temperature at 110 ℃, heating and stirring for about 1.2 hours until the modifier is nearly dry;
(4) taking off the sample cup, cooling and airing, and taking out the modified volcanic cinders filler for later use.
After the trial of 6 months, the embodiment 1 of the invention has obvious effect, realizes the aim of the invention and achieves the technical effect.
