Description
Technical field
The invention belongs to technical field of sewage, are related to a kind of coagulant original position production method for purifying polluted water body
And application.
Background technology
With the fast development of China's economy, water pollution getting worse, in order to control water pollution, country's input huge fund into
Row sewage treatment facility construction.Sewage water treatment method is broadly divided into three kinds of Physical, bioanalysis and chemical method at present.In reality
In sewage disposal process, usually several method is combined to improve treatment effect, with deepening continuously to Study on processing method,
Some minerals that are widely distributed but not yet rationally being utilized also are developed.As more and more results of study were demonstrate,proved in recent years
Real effect of the troilite in terms of sewage disposal.
Phosphorus is the one of the chief elements for leading to body eutrophication, and dephosphorization is the technology of river, lake when water body treatings
Difficult point.It is than more efficient and efficiently technological means that phosphorus, which is removed, using coagulant, but coagulant needs individually produce,
Then it transports to staying water, increases the cost of purifying polluted water body.Meanwhile it needs to be dissolved to conjunction before coagulant dosage
It can just be added after the aqueous solution of suitable concentration, which increase the complexity and operating cost of Processing tecchnics.On the other hand, contaminated
It is typically a kind of emergency measure that water body, which adds the coagulant produced in coagulant factory dystopy, because of cost, operational management etc.
Problem is difficult to become a kind of persistent measure.
The prior art has disclosed more application case, China Patent No. CN201710203729.2, and publication date is
2017.07.14 application case discloses a kind of flocculant for being used to administer black and odorous water being fabricated with bentonite etc., by
The aggregate of 75~85 mass parts and the additive of 15~25 mass parts composition, aggregate are made of modified coal ash and modified zeolite,
Additive is made of sulfonation charcoal, bentonite, matchmaker's spoil, Hanggin soil and houghite.The manufacture craft of the flocculant is：1) by powder
Coal ash and zeolite crush, and cleaning, drying after acid-modified, alkali modification obtains aggregate；2) by bentonite, matchmaker's spoil, Hanggin soil and
Houghite crushing is uniformly mixed with sulfonation charcoal, obtains additive, finally aggregate is stirred with additive, be sieved, is obtained
Coagulant.The preparation method complex process of this application needs dystopy to produce and transports to scene, can be complete after centainly operating
Into processing, and do not have lasting effects.
China Patent No. CN201410456615.5, publication date are that the application case of 2015.03.04 discloses one kind with ferrotianium
Preparation method of the ore deposit for the inorganic ferrotianium mixing coagulant of raw material.The method preparation process of this application is as follows：1) with ilmenite
For primary raw material, at certain temperature and stirring condition, be respectively adopted various concentration sulfuric acid ilmenite is dissolved after
Foam type curing, leaching two benches reaction；2) under certain temperature and stirring condition, using certain density sodium hydroxide solution
Acid-base value adjusting is carried out to above-mentioned leaching liquid, control ph is 0.5~1.5, real at being then 20 DEG C~60 DEG C in reaction temperature
Polymerisation is applied, obtains coagulant.The method of this application makes natural mineral matter ilmenite get utilization, however needs
Dissolved using sulfuric acid, in terms of environment friendly there are it is certain the defects of, in addition, the preparation process of this application method is numerous
It is trivial, and also need dystopy and produce and transport to scene, it can complete to handle after centainly operating, not have lasting effects.
The ferro-sulphur ore of China is very abundant in China, and ferrous or iron ion can be generated after being aoxidized, and is expected to useless
Water treatment field is applied, and the prior art has disclosed relevant application case, such as China Patent No. CN201310732115.5,
Publication date is that the application case of 2015.02.18 discloses a kind of natural troilite catalysis H2O2Oxidation depth handles the side of industrial wastewater
Method.For another example Chinese Patent Application No. CN201410406193.0, publication date are that the application case of 2016.03.02 discloses a kind of profit
The method that coal washing waste water flocculant is prepared with flyash and pyrite cinder, this method mix flyash with soda ash, at 850 DEG C
Lower roasting obtains Primary product, then Primary product is dissolved in hydrochloric acid, acidleach is stirred at 100 DEG C, filtering and removing slag are spare, by troilite
Slag is filtered using the same manner acidleach, and solution is compounded with above-mentioned filtrate, and flocculant is obtained after ageing.The method of this application will
Flyash and troilite, which are fully used, prepares flocculant, however preparation process is relatively complicated, and pyrite burning needs higher
Temperature condition, further increase operating cost.
The defects of based on the prior art, there is an urgent need for develop it is a kind of prepare it is easy to use, of low cost, can persistently run it is mixed
Solidifying agent production method.
Invention content
1. technical problems to be solved by the inivention
For polluted water body coagulation purification in the prior art coagulant production, operating cost it is high, it is complicated for operation, be difficult to hold
It is contaminated to purify the present invention provides a kind of using troilite as the coagulant original position production method of raw material long the problems such as operation
Water body.2. technical solution
