Abstract
The invention relates to a sewage treatment medicament, in particular to a preparation method and application of a medicament for removing heavy metal ions in water, and the technical scheme is as follows: the medicament is prepared from the following raw materials in parts by weight: 2 parts of natural weathered coal and 1 part of 30-50% sodium hydroxide solution. The preparation method comprises the following steps: 1) crushing natural weathered coal; 2) reacting weathered coal with sodium hydroxide at 60-80 ℃ for 5-10 hours; 3) clarifying the reaction solution, taking the supernatant and filtering for later use; 4) heating the supernatant to 50-60 ℃ in a reaction kettle under the protection of nitrogen for polymerization reaction for 2-3 hours; 5) and taking out the polymer and drying. The advantages are that: 1) the prepared medicament is directly put into water containing heavy metal ions without adjusting the pH value of the water when in use; 2) no toxic and harmful gas is generated after coagulation reaction; 3) the weathered coal has low raw material price and is convenient to popularize and use.
Description
Technical field
The present invention relates to sewage treatment drug, be specially and remove the Preparation method and use of heavy metal ion medicament in water.
Background technology
In heavy metal-containing wastewater treatment, use after putting into precipitation in water medicament making it precipitate, then be separated off.The medicament that precipitation uses typically has the most several: 1, use hydroxide regulation pH value to make heavy metal ion reaction in water remove after generating hydroxide precipitation；2, use addition sulfide method, be allowed to remove after reaction generates sulfide precipitation；3, employing there was added machine sulfide method, is allowed to remove after reaction generates organic sulfur compound precipitation.But above medicament all has the disadvantage that 1, uses hydroxide heavy-metal ion removal, its complex process, and needs repeatedly to regulate pH value；2, use sulfide heavy-metal ion removal, if regulation pH value is improper, be easily generated hydrogen sulfide gas, poisonous and harmful；3, using organic sulfur compound heavy-metal ion removal, material price is expensive.Therefore, find and a kind of can simple and effective removal water extremely be necessary by the medicament of heavy metal ion.
Summary of the invention
The present invention solves that the medicament using method of heavy metal ion in existing removal water is complicated, be easily generated toxic and harmful and the problem involved great expense, it is provided that a kind of remove medicament of heavy metal ion and preparation method thereof in water.
The present invention is achieved by the following technical solutions: removes the medicament of heavy metal ion in water, is made up of the raw material of following weight portion:
Natural weathered coal 2 parts, concentration are the sodium hydroxide solution 1 part of 30-50%.
Remove the preparation method of the medicament of heavy metal ion in water, comprise the following steps:
1), take natural weathered coal 2 parts to pulverize；
2), the sodium hydroxide solution of 2 parts of weathered coal particles and 1 part of 30-50% reacts 5-10 hour under the conditions of 60-80 DEG C；
3) supernatant liquid filtering is taken after, being clarified by reaction solution stand-by；
4), by supernatant under nitrogen protection, in reactor, 50-60 DEG C of polymerisation 2-3 hour it is heated to；
5), polymer composition taken out, dry, pulverize and make finished product medicament.
The invention have the advantages that 1), prepare medicament use time without the pH value regulating in water, directly throw in the water containing heavy metal ion；2), toxic and harmful will not be generated after coagulating；3), weathered coal low in raw material price, it is simple to promote the use of.
