Abstract

The invention discloses a modified rice straw blue alga treating agent. The modified rice straw blue alga treating agent is characterized by being prepared from the following raw materials by weight: 30 to 35 parts of polyacrylamide, 20 to 25 parts of cationic starch, 14 to 17 parts of floral water , 19 to 21 parts of tartrate, 18 to 20 parts of ferric citrate, 17 to 19 parts of aluminum sulfate, 16 to 18 parts of rice straw, 19 to 22 parts of grape seed, 1 to 3 parts of common cnidium fruit, 2 to 4 parts of herba eupatorii, 3 to 5 parts of fructus forsythia and 2 to 5 parts of herba artemisiae scopariae. The modified rice straw blue alga treating agent has low cost, is convenient to operate and can realize safe treatment and resourceful utilization of cyanobacterial bloom. According to the invention, sterilization and antibacterial performances of Chinese herbal medicines are utilized to modify rice straw so as to obtain the blue alga treating agent, and the blue alga treating agent can remove polluting and harmful substances like heavy metal ions, radioactive substances, carcinogenic substances and blue algae hard to treat by using frequently used water treating agents and has a plurality of substantial effects like decolouring, deodorization, dehydration, de-oiling and degerming.

Description

A kind of modified water rice straw 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 modified water rice straw 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 modified water rice straw 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 modified water rice straw blue-green algae treatment agent, it is characterized in that, made by the raw material of following weight part: polyacrylamide 30-35, cationic starch 20-25, toilet water 14-17, tartrate 19-21, ironic citrate 18-20, Tai-Ace S 150 17-19, rice straw 16-18, Semen Vitis viniferae 19-22, Fructus Cnidii 1-3, eupatorium 2-4, capsule of weeping forsythia 3-5, oriental wormwood 2-5.

The preparation method of described a kind of modified water rice straw blue-green algae treatment agent, is characterized in that comprising the following steps:

(1) Fructus Cnidii, eupatorium, the capsule of weeping forsythia, Semen Vitis viniferae, oriental wormwood decocted together in water 2-3 hour and filter, getting its filtrate and flood together with rice straw 30 minutes, drying, being ground into powder;

(2) filter residue of step (1) is sent in charring furnace, calcination processing 3-4 hour at 555-660 DEG C, takes out, and sprays toilet water and mixes 40-5-minute, dries, and is ground into powder;

(3) by ironic citrate and Tai-Ace S 150 mixing 30-40 minute, add polyacrylamide mixing 45-50 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: the method environmental friendliness of control blue-green alga bloom provided by the invention, cost be low, easy to operate, can realize blue-green alga bloom safe disposal and recycling; The present invention utilizes sterilization, the Anti-bacterium performance blue-green algae treatment agent that modification makes to rice straw of herbal medicine, can remove current quo of Conventional Water Treatment Programs reluctant heavy metal ion, radioactive substance, carcinogenic substance, blue-green algae, etc. pollution and objectionable impurities, there is the multiple efficacies such as significant decolouring, deodorization, dehydration, de-oiling, degerming.
