Description
Technical field
The present invention relates to technical field of sewage, especially a kind of eutrophied water treatment method.
Background technology
The generation of body eutrophication phenomenon is mostly derived from the excess accumulation of water body nitrogen and phosphorous nutrient material, shows as algae
Amount reproduction, fish mortality, water body is smelly, occurs being referred to as " red tide " in ocean, " water is referred to as in rivers and lakes
China ".It is physico that traditional nutritive water administration way includes wastewater treatment, Sediment Dredging, aeration cycle, algicide add etc.
Method and biological control method, but all presence investment and technical difficulty are larger, destroy lake, river natural ecosystems etc.
Problem.
With the development of modern agriculture, straw quantity is significantly increased, the t of China's agricultural crop straw annual production about 700,000,000 marks
Coal.Meanwhile with the continuous adjustment of Industry Structure, it is greatly reduced in life using stalk, causes a large amount of agricultural straws
It is remaining and burned or abandoned everywhere by field.At present, the conventional utilization ways of China's stalk include:Straw-returning, using energy source,
Feed conversion, industrial utilization etc..Therefore, new technology is developed, the effective rate of utilization of agricultural stalk is improved, realizes changing rejected material to useful resource
Utilize, have far-reaching significance to improving resource scarcity problem and preserving the ecological environment.
By taking tabacco straw as an example, national cigarette district about produces tabacco straw 4500kt every year, and overall utilization is very low, most quilts
Open incineration, not only waste of resource but also environment was polluted.
The content of the invention
The technical problem to be solved in the present invention is:Present invention proposition one kind is raw material using tabacco straw, is prepared new
Adsorbent, by the use of the new adsorbent as the sorbing material of eutrophication water, solves the eutrophy of the water bodys such as lake, river
The problems such as change is low with tabacco straw utilization rate, pollution environment.
The technical solution adopted for the present invention to solve the technical problems is:The present invention is implemented as follows;
(1) tabacco straw is gathered in, dried;
(2) tabacco straw after drying crushed, cross 60~100 mesh sieves;

DEG C/min, be passed through nitrogen protection, mould anaerobic environment, it is 500~700 DEG C to set pyrolysis temperature, set pyrolysis time be 2~
4h, room temperature is cooled to afterwards, obtain tabacco straw charcoal;
(4) tabacco straw powdered carbon it is broken, cross 60~100 mesh sieves, wash to neutrality;
(5) the tabacco straw charcoal after washing be immersed in mass concentration 10~40% aluminum sulfate and mass concentration be 50~
In 70% dimethyl diallyl ammonium chloride mixed solution, stirred 20 minutes under the conditions of 30~60 DEG C;
(6) ceric ammonium nitrate solution of mass concentration 10~40% is added into the mixed solution of step (5), at 30~60 DEG C
Under the conditions of stir 5 minutes;
(7) mixed solution of step (6) is in N2Stirred 20~40 minutes under environment and under the conditions of 30~60 DEG C;
(8) mixed solution of step (7) stands 30~60 minutes under the conditions of 20~25 DEG C;
(9) the tabacco straw charcoal of step (8) is filtered;
(10) the tabacco straw charcoal ethanol after filtering and distillation water washing;
(11) the tabacco straw charcoal after washing under the conditions of 60~80 DEG C of temperature drying, cross 60~80 mesh sieves, changed
Property tabacco straw charcoal;
(12) bed mud of eutrophication water is taken, through being dehydrated, drying, crushing, crosses 60~80 mesh sieves;
(13) the bed mud after screening and modified tabacco straw charcoal by volume 1:3 ratio mixing, obtains novel adsorption
Agent;
(13) the uniform cloth of new adsorbent is spread in eutrophication water;
(14) Sediments are excavated in the dry season, a part of bed mud gives over to making new adsorbent, largely transports to and fill out
Bury field landfill, or burning disposal.
It is raw material the beneficial effects of the invention are as follows the bed mud using tabacco straw and eutrophication water, prepares new suction
Attached dose, the new adsorbent has good absorption, exchange and settling property to nitrogen, phosphonium ion, can using the new adsorbent
Eutrophication water is administered, while can also solve the problems, such as the recycling of tabacco straw.
