Description
Technical field
The invention belongs to lead ion processing technology field more particularly to it is a kind of remove lead waste water wastewater treatment material and
Preparation method.
Background technique
With the economic development of country and the support of policy, a large amount of equipment is using battery as driving force, such as lead
Sour water battery is applied mostly in tractor, tricycle, automobile start etc., and maintenance-free lead accumulator application range is wider, packet
Include uninterruptible power supply, electrical vehicular power, battery of electric bicycle etc..Lead-acid accumulator needs to be divided into constant-current discharge according to application
(such as uninterruptible power supply) and spark (such as automobile starting battery).
It is the sorting that needs early period, broken but at present during being recycled lead-acid accumulator, while entering the useless of factory
Lead-acid accumulator a part contains sulfuric acid, and sulfur acid, spent acid do not occur mainly with the preprocessing process of waste lead acid battery to a part,
The pretreated first step of waste lead acid battery exactly pours out Waste Sulfuric Acid, and focuses on, and to sum up generates during comprehensive utilization
A large amount of leaded waste water, as direct emission pollutes environment and damage human health.
Existing lead containing wastewater treatment mainly has: chemical precipitation method, lime stone neutralisation, vulcanization-lime neutralisation-electrolysis
Method, membrane separation process, above method handle the ineffective of lead waste water, it is difficult to meet demand.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of wastewater treatment material for removing lead waste water, absorption is held
Amount is big, can effectively remove the lead ion in waste water, while preparation method is simple.
The technical scheme to solve the above technical problems is that a kind of wastewater treatment material for removing lead waste water,
It is made of raw material from the following weight: 40-50 parts of polyacrylic acid, 10-20 parts of chitosan, 5-10 parts of hemicellulose, hydrotalcite 10-
15 parts, 5-10 parts of graphene, 5-10 parts of ethylenediamine tetra-acetic acid, 5-18 parts of manganese dioxide, 3-8 parts of crosslinking agent, initiator 0.2-0.6
Part, 0.3-1 parts of coupling agent, 0.5-2 parts of compatilizer, 10-15 parts and dispersing agent 1-2 parts of foaming agent.
Based on the above technical solution, the present invention can also be improved as follows.
Further preferably as the present invention, the crosslinking agent is dihydroxymethyl dihydroxy ethyl urea, glutaraldehyde, boric acid, epoxy
Chloropropane and N, N, the mixture of one or more of-methylene acrylamide.
Further preferably as the present invention, the initiator is ferrous sulfate, benzoyl peroxide, potassium peroxydisulfate and azo
The mixture of one or more of two isobutyl cyanogen.
Further preferably as the present invention, the coupling agent is gamma-aminopropyl-triethoxy-silane or 3- glycidol ether
Oxygen propyl trimethoxy silicane.
Further preferably as the present invention, the compatilizer is maleic anhydride graft phenylethene or maleic anhydride grafted propylene
Nitrile-butadienestyrene copolymer.
Further preferably the foaming agent is azodicarbonamide, 4 as of the invention, 4 '-oxobenzenesulfonyl hydrazide, right
The mixture of one or more of toluene sulfonyl hydrazide, 4,4 '-disulfonyl hydrazides and dinitrosopentamethylene tetramine.
Further preferably as the present invention, the dispersing agent is oxidized polyethylene wax or chlorinated polypropylene wax.
The present invention also provides a kind of preparation methods of wastewater treatment material for removing lead waste water, comprising the following steps:
A, in parts by weight, under the conditions of nitrogen protection, by 40-50 parts of polyacrylic acid, 10-20 parts of chitosan, hemicellulose
5-10 parts plain, 5-10 parts and water 400-500 parts water of ethylenediamine tetra-acetic acid mixes, and obtains mixture, spare；
B, it in parts by weight, is placed in ultrasonic vibration in acid solution by 10-15 parts of hydrotalcite, is then rinsed with water to neutrality, and
In 600-800 DEG C of calcining 3-4h, then hydrotalcite is placed in 10-15 parts of the foaming agent mixtures with 100-200 parts of water, finally
Under the conditions of 300-400 DEG C of temperature, 1-2h is kept the temperature, pretreated water talcum is obtained；
C, the pretreated water talcum that in parts by weight, step B is obtained is mixed with dispersing agent 1-2 parts, 5-18 parts of manganese dioxide
