 Reverse water recovery equipment:


When organic matter in sewage is oxidized by biodegradation, organic nitrogen is converted into ammonia nitrogen. The wastewater treated by activated sludge treatment has a considerable amount of ammonia nitrogen discharged into the water, which can lead to eutrophication of water body. If water is water, it will increase the difficulty and cost of water treatment. Therefore, the discharge of secondary treatment sometimes requires nitrogen removal treatment. There are two major categories of denitrification: chemical and biological.

Processing method:

1 chemical nitrogen removal

The method used to remove ammonia nitrogen has the method of blowing, folding and chlorine and ion exchange.

They are mainly used in the internal control of factories, and are seldom used in urban sewage treatment plants.

(1) to remove method

Ammonia nitrogen in wastewater can be blown off in the gaseous state.

In wastewater, NH3 and NH4+ coexist with the following balance states:

NH3 + H2O = NH4 + + OH -

This balance is affected by pH value, and when the pH is 10.5 ~ 11.5, the ammonia in the waste water is saturated, so it is necessary to add lime.

The blowoff process involves raising the pH value of the wastewater to 10.5 ~ 11.5, and then aerating it, which is the process of the process of the deep treatment of the urban sewage in the tower, the removal of nitrogen and phosphorus.

This process is strongly influenced by temperature, with the decreasing of temperature, to achieve the rapid increase of the quantity of air required for the same treatment effect by using lime adjust pH value, calcium carbonate scaling happens in the blowoff tower, affect the operation.

In addition, the release of NH3 will cause air pollution.

Therefore, there have been many improvements to the process, such as the absorption of NH3 by the gas through H2SO4.

(2) fold point plus chlorine

In water purification engineering, chloramine is used as chemical compound nitrogen, hypochloric acid as residual chlorine, all have the bactericidal action.

[4] the depth of the municipal sewage treatment - nitrogen and phosphorus removal on the way A, B two fold point A point before the residual chlorine is basically chloramine, point B according to this, fold point after the residual chlorine is basically free chloride (free chlorine) used in the denitrification rate of chlorine quantity the fold point corresponding chlorine quantity shall prevail.

The best advantage of this method is that the ammonia nitrogen in the water can be completely removed by proper control.

In order to reduce the amount of chlorine, this method is often used with biological nitrification, with the removal of trace of ammonia nitrogen.

(3) ion exchange method

When ammonia nitrogen is removed by ion exchange method, natural ion exchangers are commonly used, such as zeolite.

Compared with synthetic resins, natural ion exchangers are cheaper and can be regenerated with lime.

The application of synthetic resin, pretreatment process and regeneration system is complicated, and the resin life is short and the application is limited.
