Description

A kind of rare-earth type blue algae treatment agent and preparation method thereof

Technical field

The present invention relates to water-treatment technology field, be specifically related to a kind of rare-earth type blue algae treatment agent and preparation method thereof.

Background technology

In recent years, along with the continuous increase of China's size of population and developing rapidly of industrial and agricultural production, water requirement rapidly increases, and water pollutions is more and more serious simultaneously.

Water pollutions is that world today's pollution is the most serious, one of pollution that hazardness is maximum, China's quantity of wastewater effluent is large, the pollutent in the rivers and lakes water bodys such as Taihu Lake is caused to grow with each passing day, pollution speed has exceeded the detergent power of lake body self, some of them are phosphorous, a large amount of discharges of nitrogenous compound, accelerate rivers and lakes eutrophication process, cause algae particularly blue-green algae distorted proliferation growth, and form one deck blue-greenish colour at the water surface and have offscum and the wawter bloom of bad smell, release stench, makes water quality degenerate.

Large-scale blue algae bloom, is called as " green tide ", exhausts water oxygen gas and cause the death of fish time serious.

More seriously, in blue-green algae, some kind (as Microcystis aeruginosa) also can produce Microcystin (microcystins is called for short MCs), containing a large amount of MCs in the green tide of about 50%.

MCs, except directly producing except murder by poisoning to fish, people and animals, is also the major incentive of liver cancer.

Blue-green algae harnessing project is a complicated systems engineering.

The main method taked the at present manpower and materials that still environmental input is a large amount of outside carry out drawing the mode that dirt removal clearly, resettlement contaminating enterprises etc. transfer the pollution, not from contaminated solution root; In environment improvement, biological process (comprising microbial method, animal law, plant method), the method for all kinds of improvement blue-green algae of chemical method and treatment agent has in succession been there is although domestic, but be still difficult to so far obtain extensively, effectively applying, major cause be that existing Treatment process is single, process is complicated, functional not high.

Summary of the invention

Object of the present invention is just to provide a kind of rare-earth type blue algae treatment agent and preparation method thereof, to overcome the deficiencies in the prior art.

The object of the present invention is achieved like this:

A kind of rare-earth type blue algae treatment agent, it is characterized in that, be made up of the raw material of following weight part: polymerize aluminum chloride 25-30, magnesium chloride 20-24, Tai-Ace S 150 19-21, rare earth compound 14-18, nanoparticle gac 18-20, boric acid 17-19, iron protochloride 15-18, Herba Houttuyniae 1-3, Flos Matricariae chamomillae 2-5, Jehol Ligusticum Rhizome 3-5, root of Dahurain angelica 2-5.

The preparation method of described a kind of rare-earth type blue algae treatment agent, is characterized in that comprising the following steps:

(1) Herba Houttuyniae, Flos Matricariae chamomillae, Jehol Ligusticum Rhizome, the root of Dahurain angelica decocted 2-3 hour together in water and filter, getting its filtrate and flood 30 minutes together with nanoparticle gac, drying, be ground into powder;

(2) filter residue of step (1) is sent in charring furnace, calcination processing 3-4 hour at 570-665 DEG C, take out ovendry power and be broken into powder;

(3) by magnesium chloride and Tai-Ace S 150 mixing 30-40 minute, add iron protochloride mixing 45-50 minute, then add boric acid mixing 50-60 minute;

(4) by step (1), (2), (3) reaction mass and other remaining components mixing 120-150 minute.

The present invention has following beneficial effect: the blue algae treatment agent that the present invention obtains is safe and efficient, energy consumption is low, coagulation performance is excellent, and alumen ustum is large and closely, the fine and close volume of mud of removal is little and settling velocity is fast.
