Description
Technical field
The present invention relates to technical field of waste water processing, and in particular to heavy metal containing wastewater treatment agent.
Background technology
What heavy metal wastewater thereby referred to discharge in the industrial processes such as mining and metallurgy, machine-building, chemical industry, electronics, instrument contains weight
The waste water of metal.Heavy metal (such as containing cadmium, nickel, mercury, zinc) waste water is to an environmental pollution most serious and the mankind is endangered maximum
One of industrial wastewater, water quality and quantity is related with production technology.Heavy metal in waste water cannot generally decompose destruction, Zhi Nengzhuan
It moves its existence position and changes its Material Form.Processing method is to reform production technology first, uses no or little the big weight of toxicity
Metal, in production site, treatment in situ is not (if discharged workshop）Located frequently with chemical precipitation method, ion-exchange etc.
Reason, heavy metal can discharge or reuse less than discharge standard in treated water.New heavy metal enriched product is formed to try one's best back
It receives and utilizes or be subject to harmless treatment.Traditional heavy metal method for treating water is as follows:Several strands of waste water are mixed, reduce heavy metals
Then concentration adds in calcium hydroxide, then adds flocculant natural subsidence.Finally discharge.This method have time-consuming, solid slag can not
The shortcomings of processing, processing cost is high and processing is incomplete.
The content of the invention
It is an object of the invention to provide the heavy metal containing wastewater treatment agent that a kind of sedimentation time is short, effect is good, at low cost and
Its preparation method, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical solution：
A kind of heavy metal containing wastewater treatment agent, is made of the raw material below according to parts by weight:3-8 parts of polyacrylamide, poly- phosphorus chlorination
15-22 parts of iron, 12-18 parts of gypsum, 20-28 parts of zeolite, 10-15 parts of sodium lignin sulfonate, 6-10 parts of polymer phosphate iron, water 50-
58 parts, 3-8 parts of calcium oxide, 12-18 parts of aluminium hydroxide, 3-8 parts of calcium chloride, 5-10 parts of activated carbon, 12-15 parts of aluminum potassium sulfate, silicon
5-8 parts of diatomaceous earth.
As further embodiment of the present invention:The heavy metal containing wastewater treatment agent, by below according to the raw material group of parts by weight
Into:4-7 parts of polyacrylamide, 17-20 parts of poly- phosphorus iron chloride, 14-16 parts of gypsum, 22-26 parts of zeolite, sodium lignin sulfonate 11-
14 parts, 7-9 parts of polymer phosphate iron, 52-56 parts of water, 4-7 parts of calcium oxide, 14-16 parts of aluminium hydroxide, 4-7 parts of calcium chloride, activated carbon
6-9 parts, 13-14 parts of aluminum potassium sulfate, 6-7 parts of diatomite.
The preparation method of the heavy metal containing wastewater treatment agent, comprises the steps of：
Polyacrylamide, poly- phosphorus iron chloride, polymer phosphate iron, calcium chloride, sodium lignin sulfonate, zeolite is taken to be put into autoclave
After being passed through vapor 4.5 atmospheric pressure is kept to carry out pressure steaming reaction, generation mixture A;
Gypsum, calcium oxide, aluminium hydroxide, activated carbon, aluminum potassium sulfate, diatomite with water are mixed, and are ultrasonically treated, ultrasound
Power is 900-1000W, ultrasonic time 45-50min, and mixture B is made;
It is maintained in the case of high-speed stirred of the Reynolds number higher than 6000 and inserts mixture A in mixture B, while by above-mentioned stirring
Mixture is water-cooled, so that the temperature of mixture is maintained at 35-40 °C, heavy metal containing wastewater treatment agent is made.
Compared with prior art, the beneficial effects of the invention are as follows：
The water treatment agent of the present invention has heavy metal a chelation under the collective effect of each raw material, and the sedimentation time is short, effect
Good, at low cost, processing completely, improves the harmful substance of degradation water and heavy metal ability, especially to the heavy metal containing high concentration
Waste water energy is effectively handled, and can be widely used for heavy metal containing wastewater treatment field, and water quality that treated can realize recycling.This hair
Bright formula is simple, of low cost, function admirable, is suitble to large-scale production.
Specific embodiment
Below in conjunction with the embodiment of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, those of ordinary skill in the art's all other embodiments obtained without making creative work, all
