Embodiment 1

[0027] Step 1. Raw material pretreatment: Put enough purchased raw materials into a grinder for grinding, grind the agglomerates therein, then pass the raw materials through a 150-mesh sieve, and store the raw materials under the sieve for later use;

[0028] Step 2, mixing processing: Weigh 30 parts of calcium hypochlorite, 2 parts of potassium ferrate, 6 parts of sodium carboxymethylcellulose and 9 parts of calcium chloride powder, and pour them into a mixer together at a speed of 15 rpm , and mix uniformly in 10 minutes to obtain the ammonia nitrogen remover;

[0029] Step 3: Sampling inspection and packing into storage: Sampling and testing the finished products of the ammonia nitrogen remover, mixing unevenly mixed materials again until the materials are evenly distributed, and packing into storage after passing the test.

Embodiment 2

Abstract

The invention discloses an ammonia nitrogen remover and a preparation method thereof. The ammonia nitrogen remover is prepared from the following raw materials in parts by weight such as 30-50 parts of calcium hypochlorite, 2-5 parts of potassium ferrate, 6-9 parts of sodium carboxymethylcellulose, and 9-12 parts of calcium chloride. The ammonia nitrogen remover relates to the technical field of water treatment. Through the ammonia nitrogen remover and the preparation method thereof disclosed by the invention, the calcium hypochlorite enables monohydrate ammonia in wastewater to overflow as nitrogen through oxidation reaction; the potassium ferrate can oxidize and decompose organic matters, microorganisms and algae, and the deposition and scaling of impurities on the pipeline wall are retarded, and the decomposition product Fe (OH)3 colloid also has the flocculation function, can adsorb and remove organic and inorganic pollutants in water, and has special effect on heavy metals; sodiumcarboxymethyl cellulose can break hydrogen bonds between water molecules and NH3 molecules, so that ammonia gas overflows; after calcium chloride reacts with hydroxyl ions to become calcium hydroxideflocculation and precipitation, part of nitrogen dioxide dissolved in water in the total nitrogen in the wastewater overflows, and the effect of reducing the total nitrogen is achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an ammonia nitrogen remover and a preparation method thereof. Background technique [0002] Ammonia nitrogen refers to the free ammonia (NH 3 ) and ammonium ions (NH 4 + ) in the form of nitrogen, high-concentration ammonia-nitrogen wastewater has a wide range of sources and a large amount of discharge, such as chemical fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc., all produce a large amount of high-concentration ammonia-nitrogen wastewater. The discharge of a large amount of ammonia nitrogen wastewater into the water body will not only cause eutrophication of the water body, cause the water body to be black and smelly, but also increase the difficulty and cost of water supply treatment, and even cause poisonous effects on people and organisms. Pollution control, energy saving and emission reduction have become important issues in the imp...
