Description
Technical field
The present invention relates to treating landscape water body fields, and in particular to a kind of ammonia nitrogen removal agent for polluted scenic waters
And its prepare application method.
Background technology
Landscape water body is component part important in urban ecological system, and most of city appearance water body is closing water
Body, make-up water source is few, and water body flow is poor, small from net capacity, the eutrophication of water quality deterioration and water body easily occurs.In recent years,
With the fast development in city, rainwash, sanitary sewage and industrial wastewater rich in nutritive salt are directly discharged to urban landscape
In water body, so that water body is subject to serious pollution and increasingly aggravate, bring great danger to the production of the mankind, life
Evil.
Ammonia nitrogen is one of most important polluter of eutrophication water, when the ammonia-nitrogen content in water body is excessively high, just
The algae in water body can be caused to breed rapidly, form wawter bloom so that accumulate the harmful substances such as a large amount of algae toxins in water.Together
When, the dissolved oxygen in water body is largely consumed because of the nitrification of microorganism, is caused water degradation, is deteriorated, blacks smelly.This
Outside, fish are more sensitive to ammonia nitrogen in water, when ammonia-nitrogen content Gao Shihui causes fish dead.
Currently, making a general survey of the quick removal technology of ammonia nitrogen in landscape water body, two major classes can be divided into：Physico-chemical process and bioanalysis.
Wherein, physico-chemical process is mainly absorption method and the precipitation method；The effects that bioanalysis is mainly the nitrification using microorganism will be in water body
Ammonia nitrogen removal.Although there are many methods for the ammonia nitrogen in landscape water body, there are removal effect unobvious in practical applications, goes
The problems such as low except efficiency.
Invention content
The purpose of the present invention is to provide a kind of ammonia nitrogen removal agent for polluted scenic waters and the prior arts not
Together, the ammonia nitrogen removal agent removal effect is good, removal efficiency is high.The present invention actually also effectively increases ammonia nitrogen removal agent each component
Effective rate of utilization.In addition the present invention is also very notable to the removal effect of total phosphorus.
The present invention is achieved through the following technical solutions：
A kind of ammonia nitrogen removal agent for polluted scenic waters is adsorbed by zeolite powder, Graphene powder, flocculant, auxiliary
Agent forms, and additional adsorbents are the one or two of aluminium silicate salt adsorbent or silicates adsorbent.
The application environment of existing ammonia nitrogen removal agent is often that ammonia nitrogen concentration is up to 1000mg/L industrial wastewaters and lives useless
Water needs although its removal rate can be made to be up to 90% using absorption method or chemical precipitation method deamination by purifier
The processing mode of a large amount of dosings realizes that remover dosage is generally large.And the landscape water body that the present invention applies is mostly big water surface water
The content of body and itself ammonia nitrogen is relatively low, and general water quality of landscape water meets《Water environment quality standard》(GB3838-
2002) V class water quality standard, ammonia nitrogen concentration are less than 2mg/L, under eutrophic state the ammonia nitrogen concentration of landscape water body be generally 3~
8mg/L, slightly the ammonia nitrogen concentration of landscape water body is said from reducing in difficulty, contaminated landscape only in 8~15mg/L under black smelly state
The ammonia nitrogen of water body quickly reduces the complexity that complexity is much larger than industrial water body.Exactly the present invention innovate by zeolite powder,
Graphene powder, additional adsorbents are effectively arranged in pairs or groups so that are generated effective synergistic effect between zeolite powder and Graphene powder, and coordinated
The auxiliary of additional adsorbents is adsorbed so that ammonia nitrogen removal agent of the invention is applying the ammonia nitrogen removal effect in landscape water body aobvious
It writes, removal efficiency height.
