Abstract
The invention relates to a chemical reagent, in particular to a novel water purifying agent for sewage treatment. The novel water purifying agent is prepared from, by weight, 20-40 parts of sodium sulfate, 10-20 parts of polyacrylamide, 5-15 parts of sodium metasilicate pentahydrate and 20-50 parts of sodium phosphate. Polyacrylamide used in water purifying agent is easily dissolved in water and excellent in coagulate effect, the product stability is good, the applicable pH value range is wide, the pH of water treated with the water purifying agent is hardly reduced, at the same time, inorganic ingredients and organic ingredients are synergized to serve as a coagulant, and the water purifying agent is excellent in flocculation effect and has the advantages of being rapid in purification speed, good in effect, environmental friendly, free of toxins and the like.
Description
Technical field
The invention belongs to technical field of sewage, specifically a kind of water purification agent and its application.
Background technology
Because population increases and economic development, the impact money that the excessive exploitation and unreasonable development of resource are produced
The series of problems of source quality, these problems have directly threatened the existence of we and descendants.
China is equally faced with these problems, and China is the country of a water resources shortage, how to alleviate water resources shortage
And have become an instant problem the problems such as pollution.
At present, processing water resource pollution problem has various methods such as physics, chemistry, biology, synthesis, but physical method is more
There is treatment effect not good, handling rate instability problem；Biological method processing cost is too high, is not suitable for promoting the use of；It is adopt more
Chemical method is processing sewage, but existing water purification agent, and there is secondary pollution, one also had to environment in its agent formulations
Fixed impact.
The content of the invention
In view of the defect that prior art is present, the invention aims to provide a kind of low evil of low toxicity, high efficiency, low cost, fit
With the wide water purification agent of scope.
The technical scheme that the present invention is provided is as follows：
A kind of purifying agent, is made up of the raw material of following parts by weight：Sodium sulfate 20-40 parts, polyacrylamide 10-20
Part, five hydrated sodium metasilicate 5-15 parts and sodium phosphate 20-50 parts.
Preferably, described purifying agent, is made up of the raw material of following parts by weight：Sodium sulfate 30-35 parts, poly- third
Acrylamide 10-12 part, five hydrated sodium metasilicate 10-12 parts and sodium phosphate 30-35 parts.
Preferably, described purifying agent, is made up of the raw material of following parts by weight：30 parts of sodium sulfate, polypropylene
35 parts of 12 parts of amide, 10 parts of five hydrated sodium metasilicate and sodium phosphate.
Compared with prior art, the device have the advantages that being：
Polyacrylamide coagulation effect soluble in water that the purifying agent of the present invention is selected is excellent, product stability is good etc.
Deficiency, is suitable for pH value range extensively, and the pH of water reduces little after process, while being cooperateed with organic components as mixed using inorganic matters
Solidifying agent so that effect of the present invention with excellent flocculation, the present invention has purification speed fast, and effect is good, and environment-protecting asepsis etc. are excellent
Point.
Specific embodiment
With reference to specific embodiment, further details of elaboration is made to the present invention, but embodiments of the present invention are not
It is confined to the scope that embodiment is represented.
Embodiment 1：

The purifying agent of the present invention when in use, only need to add the water purification agent of 1.0ppm in treatment sewage, you can
Significantly improve effect of settling.And, the COD and chromaticity index of water also can improve significantly after process.
The sewage of certain sewage treatment plant is processed using the purifying agent obtained in embodiment of the present invention 1-3, and
The Con trolling index row of the sewage after before processing is tested, sewage after the water purification agent obtained in embodiment 1-3 process, water outlet
Water quality items Testing index can reach the limit value of sewage drainage standard.
It is aforementioned to the present invention specific illustrative embodiment description be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
