Problems solved by technology

Among them, the use of physical and chemical methods to purify water bodies is an efficient and simple technical method widely used in the treatment of concentrated high-concentration wastewater. However, the commonly used artificial media materials have their own shortcomings or deficiencies. The ideal is that the cost is high, or it has certain pollution or subsequent utilization is difficult, so it has become a bottleneck in the development of sewage treatment technology to a certain extent.

Embodiment 1

[0022] Embodiment 1: The purification agent of this embodiment is more suitable for use in water bodies with less nitrogen (N) and phosphorus (P) pollution.

[0023] 1. Based on the total weight of the purifying agent, the purifying agent in this embodiment contains 80% by weight of bio-black carbon and 20% by weight of cement.

[0024] 2. Preparation method:

[0025] The bio-black carbon and cement of the above-mentioned components are pulverized into powder, mixed uniformly, and then processed into small spherical particles with a diameter of 2-5 mm.

Embodiment 2

[0026] Embodiment 2: The purification agent of this embodiment is more suitable for use in water bodies that are relatively heavily polluted by nitrogen (N) and phosphorus (P).

[0027] 1. Based on the total weight of the cleaning agent, the cleaning agent in this embodiment includes 40% by weight of bio-black carbon, 20% by weight of hydrated iron oxide, 20% by weight of attapulgite clay, 15% by weight of cement and 5% by weight of One or more of auxiliary agents such as gypsum or polyacrylamide.

[0028] 2. Preparation method:

[0029] The above components of bio-black carbon, hydrated iron oxide, attapulgite clay, cement, gypsum, polyacrylamide and other auxiliary agents are pulverized into powder, mixed evenly, and then processed into spherical particles of 2-5 mm in size.

Embodiment 3

[0030] Embodiment 3: The purification agent of this embodiment is more suitable for use in water bodies with relatively heavy nitrogen (N) pollution.

[0031] 1. Based on the total weight of the cleaning agent, the cleaning agent in this embodiment comprises 60% by weight of bio-black carbon, 5% by weight of hydrated iron oxide, 20% by weight of attapulgite clay, 10% by weight of cement, and 5% by weight polyacrylamide.

Abstract

The invention relates to an environment-friendly sewage nitrogen and phosphorus removal cleaning agent and a preparation method thereof. The environment-friendly sewage nitrogen and phosphorus removal cleaning agent is characterized in that the cleaning agent contains 40-80 percentage by weight of biological black wood charcoal, 0-20 percentage by weight of hydrated iron oxide, 0-20 percentage by weight of attapulgite and 0-20 percentage by weight of cement on the basis of the total weigh of the cleaning agent. The cleaning agent preparation method comprises the following steps of: (1) uniformly mixing the powdery iological black wood charcoal, the hydrated iron oxide, the attapulgite, the cement and the like by weight percent; and (2) processing the mixture obtained in step (1) into granulates. The cleaning agent provided by the invention has the advantages of large specific surface, suitability for purification of multiple water bodies, reliable purification effect of sewage, low construction cost, convenience for use, environmental friendliness, wide source of raw materials, stable property of basic component materials and contribution to construction of a circular economy pattern.

Description

technical field [0001] The invention belongs to the field of sewage purification, and specifically relates to an environment-friendly sewage purifying agent with the function of denitrification and phosphorus removal and a preparation method thereof. It can purify the water body, and the sewage purification efficiency is high. After the water body is purified, the waste can be used as a fertilizer resource. Background technique [0002] With the rapid development of economy and society, the amount of sewage discharge is increasing year by year, and the water pollution caused by industry, agriculture and residents' life is becoming more and more serious. Sewage treatment has become a hot topic nowadays. So far, sewage purification methods can be divided into four categories according to their functions, namely physical treatment, chemical treatment, physical chemical treatment and biological treatment. Among them, the use of physical and chemical methods to purify water bodi...
