Description

A kind of ecological, environmental protective water purification agent of quick elimination black and odorous water ammonia nitrogen

Technical field

The invention belongs to the technologies that field is administered in waters, are suitable for the black and odorous waters such as river, lake and administer, further It says more particularly to a kind of ecological, environmental protective water purification agent of quick elimination black and odorous water ammonia nitrogen.

Background technology

As modern social development is getting faster, living standards of the people are continuously improved, a large amount of sanitary sewage, agricultural irrigation Water, house refuse, industrial wastewater and the larger rainwash of pollutional load flow directly into water body so that river ammonia nitrogen concentration ratio It is higher.Need how a kind of method of quick reduction water body ammonia nitrogen concentration reduces water body ammonia nitrogen in practical engineering application at present Concentration, it is the key that comprehensive improvement black and odorous water method to improve water quality.This method provides a kind of quickly elimination black and odorous water The ecological, environmental protective water purification agent of ammonia nitrogen produces the ammonia nitrogen in the macromolecule inorganic compound soluble in water by rack-like structure and waste water Raw reaction, generates nitrogen (N₂), the form that mineralized nitrogen is nitrogen is removed.

Invention content

The present invention is that water quality raises agent 6, to solve above-mentioned technical problem and the technical solution adopted is that providing a kind of fast Speed eliminates the ecological, environmental protective water purification agent of black and odorous water ammonia nitrogen, is mainly compounded by raw materials such as a variety of inorganic compounds, chelating agent, auxiliary agents Form, be a kind of efficient, nontoxic, free of contamination novel ecological environmental protection water purification agent, given full play in processing procedure catalysis oxidation, The synergistic effects such as flocculation, absorption, coprecipitated, reduce water body ammonia nitrogen concentration.It is imitated in pH range 4-12, wherein 6-9 that this product uses Fruit is more preferably.Many of inorganic compound proportion ranging from 60%-80%, chelating agent 5-15%, auxiliary agent 3%-10%.

Description of the drawings

Fig. 1 is ammonia nitrogen variation tendency schematic diagram in water.

Fig. 2 is that ammonia nitrogen degradation agent adds concentration and degradation effect schematic diagram.

Specific implementation mode

The invention will be further described with reference to the accompanying drawings and examples.

Wherein, specific technical solution is：

Test water：Pick up from the river water sample of my company governance.River water is taken to filter removal large volume floating through mono layer gauze Object and suspended matter, every bottle of cylinder amount of being filled with water are 2L, and static 2h after water is added, spare.

Test procedure：It tests group # and sample concentration is added and carried out with reference to table 1, blank control group (CK) is no added, adds Enter after medicament stirs evenly, in for 24 hours, ammonia nitrogen concentration content in 48h and 72h detection water.

1 ammonia nitrogen degradation agent of table adds concentration

Testing result

Ammonia nitrogen is measured using HJ535-2009 Berthelot spectrophotometries.Add medicament for 24 hours, after 48h and 72h, use phase The ammonia-nitrogen content of sample sets and blank group is detected with method, each testing result is shown in Table 2, and water sample ammonia nitrogen changes of contents trend is shown in Fig. 1. As seen from Figure 1, ammonia-nitrogen content has obstructed degree to reduce in test specimen after such ammonia nitrogen degradation agent of 2~7 test groups addition. It can be obtained by table 1, ammonia-nitrogen content reduces by 2.5%, 3.2%, 5.6%, 5.8%, 6.1% and to 2~No. 7 test groups respectively for 24 hours 7.7%, subsequent No. 7 test group ammonia-nitrogen contents begin with slightly to go up, and 1~No. 7 test group 72h ammonia-nitrogen content declines successively 0.7%, 2.3%, 2.3%, 4.4%, 6.0%, 9.9% and 7.9%, blank group ammonia-nitrogen content declines 1.4%, 2~No. 7 experiments Group is above blank group ammonia nitrogen degradation rate.Wherein, 4~No. 7 test group dosage degradation of ammonia nitrogen significant effects.

7 test groups are designed in this experiment, experiment proves that ammonia nitrogen degradation agent has remarkable result to ammonia nitrogen in degradation water. 4~No. 7 test group ammonia-nitrogen contents decline obviously, and dosage is followed successively by 50mg/L, 60mg/L, 70mg/L and 80mg/L, and this is applied Dosing dosage, 72h stability are preferable.Ammonia nitrogen degradation agent adds concentration and degradation effect Fig. 2.

Although the present invention is disclosed as above with preferred embodiment, however, it is not to limit the invention, any this field skill Art personnel, without departing from the spirit and scope of the present invention, when can make a little modification and it is perfect, therefore the present invention protection model It encloses to work as and is subject to what claims were defined.
