Abstract

The invention discloses a high-adsorbability blue algae treatment agent. The high-adsorbability blue algae treatment agent is characterized by being prepared from the following raw materials in parts by weight: 27-30 parts of polymerized ferric chloride, 17-19 parts of aluminum potassium sulfate, 15-18 parts of bentonite, 16-19 parts of acrylamide, 17-20 parts of ascorbic acid, 14-17 parts of calcium peroxide, 1-3 parts of rhubarb, 2-5 parts of Chinese honeylocust fruit, 3-6 parts of shrubalthea bark and 1-4 parts of ulmus macrocarpa hance. The algae removal water purifying agent disclosed by the invention can be used for effectively realizing the adsorption effect of the bentonite and the effects of coagulation, charge neutralization and the like of polycations by adding Chinese herbal medicines and performing calcination treatment, is large and dense in alum flocs, fast in sedimentation speed and significant in effect of removing blue algae suspended matters, turbidity, nitrogen, phosphorus and the like, ensures that a water body is transparent and stable in water quality and pH value after being treated, and furthermore integrates the effects of a corrosion inhibitor, a bactericide and other medicaments.

Description

A kind of high absorbability 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 high absorbability 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 high absorbability 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 high absorbability blue-green algae treatment agent, it is characterized in that, made by the raw material of following weight part: poly-ferric chloride 27-30, potassium aluminium sulfate 17-19, wilkinite 15-18, acrylamide 16-19, xitix 17-20, calcium peroxide 14-17, rheum officinale 1-3, Chinese honey locust 2-5, Shrubalthea Bark 3-6, overgrown with weeds smooth 1-4.

The preparation method of described a kind of high absorbability blue-green algae treatment agent, is characterized in that comprising the following steps:

(1) by rheum officinale, Chinese honey locust, Shrubalthea Bark, overgrown with weeds smooth decoction in water together 2-3 hour and filtration, get its filtrate and flood together with wilkinite 30 minutes, dry, be ground into powder;

(2) filter residue of step (1) is sent in charring furnace, calcination processing 3-4 hour at 570-655 DEG C, takes out ovendry power and is broken into powder;

(3) by potassium aluminium sulfate and acrylamide mixing 30-40 minute, add xitix mixing 45-50 minute, then add calcium peroxide 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: algae-removing water-purifying agent of the present invention has been brought into play the effect such as coagulation, charge neutrality of bentonitic absorption property and polycation effectively by adding herbal medicine and calcination processing, alumen ustum is large and tight, settling velocity is fast, remove the suspended substance such as blue-green algae, turbidity, nitrogen phosphorus texts remarkable, and water body after treatment is transparent, water quality and acid-basicity are stable, have effect of the various medicaments such as inhibiter, sterilant concurrently simultaneously.

Embodiment

Described a kind of high absorbability blue-green algae treatment agent, it is characterized in that, made by the raw material of following weight part: poly-ferric chloride 29, potassium aluminium sulfate 18, wilkinite 15, acrylamide 16, xitix 17, calcium peroxide 14, rheum officinale 1, Chinese honey locust 5, Shrubalthea Bark 3, overgrown with weeds smooth 4.

Making method comprises the following steps:

(1) by rheum officinale, Chinese honey locust, Shrubalthea Bark, overgrown with weeds smooth decoction in water together 2-3 hour and filtration, get its filtrate and flood together with wilkinite 30 minutes, dry, be ground into powder;

(2) filter residue of step (1) is sent in charring furnace, calcination processing 3-4 hour at 570-655 DEG C, takes out ovendry power and is broken into powder;

(3) by potassium aluminium sulfate and acrylamide mixing 30-40 minute, add xitix mixing 45-50 minute, then add calcium peroxide mixing 50-60 minute;
