Description

A kind of rare-earth type blue-green 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-green 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 pollutes more and more serious simultaneously.

It is that world today's pollution is the most serious that water pollutes, one of pollution of hazardness maximum, China's quantity of wastewater effluent is large, cause the pollutent in the rivers and lakes water bodys such as Taihu Lake 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 the particularly abnormal breeding growth of blue-green algae of algae, and form one deck blue-greenish colour and to have the offscum of stench taste be wawter bloom at the water surface, discharge stench, water quality is degenerated.

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

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

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

It is a complicated systems engineering that blue-green algae is administered engineering.

The main method of taking at present still outside a large amount of manpower and materials of environmental input draw the mode that dirt removal clearly, resettlement contaminating enterprises etc. are transferred the pollution, not contaminated solution root; Aspect interior environmental improvement, method and the treatment agent of biological process (comprising microbial method, animal law, plant method), all kinds of improvement blue-green algaes of chemical method have in succession been there is although domestic, but be still difficult to so far obtain extensively, effectively application, major cause is that existing improvement technology 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-green 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-green algae treatment agent, it is characterized in that, made by 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-green 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 together in water 2-3 hour and filter, getting its filtrate and flood together with nanoparticle gac 30 minutes, drying, being ground into powder;

(2) filter residue of step (1) is sent in charring furnace, calcination processing 3-4 hour at 570-665 DEG C, takes out ovendry power and is 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) step (1), (2), (3) reaction mass and other remaining components are mixed to 120-150 minute.

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