Abstract
The invention discloses an efficient heavy metal trapping agent. The heavy metal trapping agent is prepared from, by mass, 20-40% of attapulgite clay, 10-20% of sodium sulphide, 5-15% of sodium dithiocarbamate, 10-20% of polyaluminum sulfate and the balance deionized water. Through the compounding of the medicinal materials above, the highly efficient heavy metal trapping agent can play a role in not only reducing processing costs in using organic sulfur to conduct process, but also avoiding the shortcomings of large amount of mud and incomplete processing effects caused by mere use of a conventional flocculating agent; meanwhile, coagulants such as PAC are not needed after using the heavy metal trapping agent, the heavy metal trapping agent can directly form a floc with a heavy metal, thus greatly saving processing space of a water treatment workshop.
Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of efficient heavy agent for capturing.
Background technology
In existing process for treating heavy-metal waste water, conventional method is difficult to wastewater treatment to qualified discharge, only uses
Water body could be processed up to standard by special heavy metal chelating agent.Metal agent for capturing is a kind of chemical industry with heavy metal ion strength chelating
Medicament, because can be in normal temperature and very wide pH value condition and range, with the Cu in waste water2+、Cd2+、Hg2+、Pb2+、Mn2+、Ni2+、Zn2 +、Cr3+Carry out chemical reaction etc. various heavy metal ion, and be quickly generated insoluble, low water content, easy mistake at short notice
Filter off the flocculent deposit removing, thus reaching the chemicals of heavy-metal ion removal from water to be referred to as heavy metal chelating agent.
In existing heavy metal chelating agent, based on organic sulfur, but because organic sulfur synthesizes relatively costly, chemical feeding quantity also not
Low, some small-sized Electroplate Factories are difficult to hold the processing cost can standing costliness.
Content of the invention
It is an object of the invention to provide a kind of efficient heavy agent for capturing with low cost.
For achieving the above object, the present invention provides following technical scheme：
A kind of efficient heavy agent for capturing, according to mass percent, is prepared from the following components：Recessed native 20～
40%th, vulcanized sodium 10～20%, nabam 5～15%, PAFS 10～20%, balance of deionization
Water.
As the further scheme of the present invention：According to mass percent, it is prepared from the following components：Recessed native 20%,
Vulcanized sodium 20%, nabam 15%, PAFS 20%, balance of deionized water.
As the further scheme of the present invention：According to mass percent, it is prepared from the following components：Recessed native 30%,
Vulcanized sodium 15%, nabam 13%, PAFS 15%, balance of deionized water.
As the further scheme of the present invention：According to mass percent, it is prepared from the following components：Recessed native 40%,
Vulcanized sodium 10%, nabam 10%, PAFS 10%, balance of deionized water.
As the further scheme of the present invention：Described nabam is SDD
Or sodium diethyldithiocarbamate.
The compound method of described efficient heavy agent for capturing, concretely comprises the following steps：According to above-mentioned mass percent, weigh recessed
Soil, vulcanized sodium, nabam, PAFS and deionized water, obtain after fully mixing dissolving.
The consumption of described efficient heavy agent for capturing is：This agent for capturing of 1ppm can catch the heavy metal of 15ppm.
Compared with prior art, the invention has the beneficial effects as follows：
In the component of the present invention：Recessed soil (attapulgite clay) is a kind of natural materials, and heavy metal has good absorption effect
Fruit and flocculating effect, and cheap, wide material sources, but when being used alone, mud amount is larger；Vulcanized sodium is a kind of conventional process
The medicament of heavy metal, can carry out contact break conjunction to the heavy metal of complex state；Nabam is a conventional huge sum of money on market
Belong to agent for capturing, high intractable heavy metal can be precipitated；PAFS is also one kind of flocculant, to a part huge sum of money
Belonging to such as antimony, lead has good effect, and its shortcoming is then that chemical feeding quantity is big, and after process, mud amount is many.
The present invention passes through the compounding of above medicament, can play the processing cost both having reduced using organic sulphuring treatment, keep away again
Exempt from due to the effect the shortcomings of mud amount that only led to using conventional flocculant is big, treatment effect is incomplete, meanwhile, heavy using this
After metal agent for capturing, without using coagulant such as PAC (aluminium polychloride), can directly and heavy metal formed flco, greatly save
Process space between water treatment vehicle.
When the waste water containing heavy metal being processed using this heavy metal chelating agent, high treating effect, and component concave soil
For natural materials, have the characteristics that cheap, raw material sources are wide, therefore, efficient heavy agent for capturing of the present invention has process
The advantage that effect is good, processing cost is low.
