Description
Technical field
The present invention relates to water body treating field technology, espespecially a kind of black and odorous water repairs medicament and preparation method thereof.
Background technique
With the quickening of urbanization paces and the raising of industrialization degree, excessive life, production discharge of wastewater are caused
The eutrophy of water body, microorganism consume oxygen mass propagation in the water body, so that water body nigrescence is smelly.The property of black and odorous water
It is mainly shown as strong reducing property, the serious polluted-water of pollutant, and is generated along with stench, unsuitable aquatile is raw
It deposits, aquatic vegetation degenerates and even becomes extinct, and only a small amount of resistant type such as phytoplankton, zooplankter, zoobenthos etc. is deposited
?.The black smelly river ecosystem that do not only result in of water body is destroyed, and seriously affects people's lives life, so black smelly
Water body treating becomes water environmental problems urgently to be resolved in my excessively current city river pollution problem.
Administering the method for black and odorous water at this stage includes: foreign aid's blocking, endogenous control, purification of water quality, restoration of the ecosystem etc., but
The constituent species that most of existing medicament works to black and odorous water processing are more single, and content is generally less, the effect played
Fruit is limited, and not only the processing time is long, and administration way is complicated, needs special machinery to add, expends a large amount of financial resource and material resource, and not
Black and odorous water pollution problem can be thoroughly solved, the water body after improvement is easy rebound, reappears black smelly situation.Therefore, research and development are high
It imitates lasting black and odorous water and administers agent, be the research emphasis and difficult point of current black and odorous water processing.
Patent CN20151085861R7.1 disclose it is a kind of administer black and odorous river complex microorganism preparations and its preparation side
Method, it is intended to Water quality and the removal bed mud for improving black and odorous river are black smelly, but with add chemical agent (such as calcium nitrate, mistake
Calcium oxide etc.) it compares, improve black and odorous water usually more slow process, and black smelly water by adding microorganism formulation
The dissolved oxygen levels of body are relatively low possibly even to reach anaerobic horizontal, and beneficial microbe is usually suppressed, if not to anaerobism ring
The phenomenon that border is transformed, and the time for administering black and odorous water will extend, and results even in the rebound of black smelly phenomenon appearance；Patent
CN102491502A only uses calper calcium peroxide and carries out dissolved oxygen levels in increase water body, and for black and odorous water, calper calcium peroxide is slow
The material just no longer has repair after the completion of releasing, and no longer works to black smelly phenomenon rebound, so repairing to black and odorous water
It acts on again limited；Patent CN107572610A discloses a kind of black and odorous water inorganic agent and its application method, but wherein uses
Polyacrylamide PAM generates acrylamide (AM) after hydrolyzing, and has neurotoxicity, potential unfavorable to ecological environment
Risk.

Comparative example 2
It matches black and odorous water of the invention and repairs medicament, referring to the proportion of embodiment 2, comparative example 2 is obtained to repair medicament
Reparation medicament difference with embodiment 2 is only that the inner nuclear material of comparative example 2 is without composite bacteria preparation, with the raw material of inner nuclear material
Cement replaces composite bacteria preparation, remaining raw material and preparation process are constant.
Black and odorous water made from this comparative example is repaired into the reparation that medicament is applied to practical pollution black and odorous water and bed mud, packet
Include following specific steps: being reconnoitred by the practical black and odorous water of Shenyang south river, specify main pollutant be ammonia nitrogen,
Organic pollutant etc., the black and odorous water for choosing certain black smelly bed mud and certain volume, which is placed in 1L beaker, carries out beaker experiments,
Wherein, black smelly bed mud: black and odorous water=2:1, it is 30mg/g that black and odorous water, which repairs medicament throwing amount,.Delivering medicament is examined again after 15 days
Survey, compared by embodiment 2 and comparative example 2 it can be concluded that, acid volatile sulfide (AVS) is from 675mg/kg bed mud, decline
To 176.6mg/kg bed mud, removal rate comparing embodiment 2 poor 20% or more；Ammonia nitrogen drops to 3.62mg/L from 6.28mg/L,
Removal rate comparing embodiment 2 poor 10% or more；Oxidation-reduction potential is increased to -111.22mv, enhancing rate ratio from -197.70mv
Poor compared with embodiment 2 15.9%；Dissolved oxygen is increased to 2.9mg/L from 0mg/L, the poor 0.9mg/L of enhancing rate comparing embodiment 2.
By embodiment and comparative example can be seen that raw material in technical solution of the present invention be easy to get and it is environmentally friendly, use
Convenient, of the invention preparation method is simple, at low cost.
From the above results, black and odorous water of the present invention administers medicament, there is the work of slow release to oxygen and hypochlorite
With and slow release effect is preferable, and the amount added into water body is controllable, and the oxygen and hypochlorite ion for being sustained out can be improved black
The oxidation-reduction potential of smelly water body, oxidation ammonia nitrogen and the release for inhibiting sulphur.In addition, after slow-releasing agent release is over, compound bacteria
Microorganism in agent changes environment locating for black and odorous water, to increase by photosynthetic, breathing and anabolic effect
Dissolved oxygen and promotion oxidation-reduction potential in water body, reduce the acid volatile sulfide in ammonia nitrogen and bed mud, avoid sustained release
The phenomenon that there is the phenomenon that black smelly rebound, more avoids black and odorous water secondary pollution in black and odorous water after medicament release is over.It is logical
The effect of chemistry and biology is crossed, efficiently, constantly black and odorous water can be repaired
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
