Embodiment 1

[0029] One embodiment of the present invention provided: a method for preparing an efficient nitrogen remover for rural domestic sewage treatment, comprising a reactor, the nitrogen remover composition comprising: calcium hypochlorite, calcium chloride, polyethylene glycol, sodium carboxymethyl cellulose, potassium phosphate, activated carbon, additives and water; calcium hypochlorite selected 45-53 parts, calcium chloride selected 23-28 parts, sodium carboxymethyl cellulose selected 15-19 parts, potassium phosphate selected 14-16 parts, activated carbon selected 2-3 parts, polyethylene glycol selected 7-13 parts.

[0030]Additive ingredients include: magnesium oxide, sodium chloride, nitric acid and deionized water; magnesium oxide selected 12-16 parts, sodium chloride selected 10-15 parts, nitric acid selected 6-9 parts, deionized water selected 21-27 parts.

[0031] Sequentially add a fixed amount of calcium hypochlorite, calcium chloride, sodium carboxymethyl cellulose, potass...

Embodiment 2

[0033] One embodiment of the present invention provided: a preparation method for efficient nitrogen remover for rural domestic sewage treatment, additive preparation process:

[0034] S1, according to the amount of magnesium oxide, sodium chloride, nitric acid and deionized water, magnesium oxide and sodium chloride grinded into a powder, the material is stored separately;

[0035] S2, first the magnesium oxide and sodium chloride are quantitatively added to the reactor, and then the nitric acid and deionized water are added to the reactor in turn;

[0036] S3, the reactor temperature is set between 40-50 °C, the reaction time is 2-3 hours, and the speed in the reactor is set at 1500 rpm;

[0037] S4, take out the resulting additives.

[0038] Nitrogen remover preparation process:

[0039] S1, according to the amount of calcium hypochlorite, calcium chloride, sodium carboxymethyl cellulose, potassium phosphate and activated carbon in turn ground into a powder, stored separately; ...

Embodiment 3

[0044] One embodiment provided by the present invention: an application of an efficient nitrogen remover for rural domestic sewage treatment, S1, select 100ml of domestic sewage, the resulting nitrogen remover is added to the domestic sewage sample, to obtain 100ml of domestic sewage needs the amount of nitrogen remover;

[0045] S2, according to the amount of stored domestic sewage to calculate the amount of nitrogen remover required for treatment, the corresponding amount of nitrogen remover is selected;

[0046] S3, the selected nitrogen remover is evenly poured into the domestic sewage storage device to remove nitrogen from the domestic sewage.

[0047] Nitrogen removal does not increase the by-products of condensation at the same time, and the nitrogen removal effect is better.

Abstract

The invention relates to the technical field of domestic sewage treatment, in particular to a preparation method and application of an efficient nitrogen removal agent for rural domestic sewage treatment. According to the technical scheme, the nitrogen removal device comprises a reaction kettle and a nitrogen removal agent, wherein the nitrogen removal agent comprises calcium hypochlorite, calcium chloride, polyethylene glycol, sodium carboxymethyl cellulose, potassium phosphate, activated carbon, an additive and water; the additive comprises magnesium oxide, sodium chloride, nitric acid and deionized water; the preparation method comprises the following steps: sequentially adding certain amounts of calcium hypochlorite, calcium chloride, sodium carboxymethyl cellulose, potassium phosphate and activated carbon into a reaction kettle, sequentially adding polyethylene glycol and water into the reaction kettle, and finally adding an additive. The method has the advantages of no increase of condensed by-products during nitrogen removal and better nitrogen removal effect.

Description

Technical field [0001] The present invention relates to the field of domestic sewage treatment technology, specifically a preparation method and application of an efficient nitrogen remover for rural domestic sewage treatment. Background [0002] Domestic sewage is the wastewater discharged from the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and bathrooms of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter present in domestic sewage is extremely unstable, easy to decay and produce a foul odor. Bacteria and pathogens multiply in large quantities by feeding on organic matter in domestic sewage, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before it is discharged. [0003] When domestic sewage treatment needs...
