Embodiment 1

[0036] A high-efficiency phosphorus removal agent, formulated according to the following mass percentages:

[0037] 30kg of metal compounds, including 10kg of aluminum sulfate, 15kg of ferrous sulfate, and 5kg of lanthanum oxide;

[0038] 10kg of natural mineral powder, including 5kg of bentonite, 3kg of attapulgite, and 2kg of diatomite;

[0039] 10kg of flocculant, including 6kg of polyferrosilicate flocculant and 4kg of polyacrylamide;

[0040] Activated carbon 5kg;

[0041] Coagulant aid 5kg, including calcium oxide 2kg, calcium hydroxide 3kg.

[0042] as per figure 1 The process shown in the preparation of high-efficiency phosphorus removal agent, the specific steps are:

[0043] a. Prepare the raw materials of each component of the high-efficiency phosphorus removal agent according to the above-mentioned mass percentage;

[0044] b. Spray the liquid raw material on the solid raw material and dry it, grind the solid raw material and mix it;

[0045] c. Sinter all the ...

Embodiment 2～ Embodiment 5

[0049] The difference between Example 2-Example 5 and Example 1 is that the distribution ratio of each component is different, see Table 1 for details.

[0050] The composition distribution ratio of table 1 embodiment 2~embodiment 5

[0051]

[0052] Taking the production sewage of a shelf production plant in Jiangning, Nanjing as a sample, the Juhuihai JX-305 phosphorus removal agent produced by Jiangxi Huihai Environmental Protection Technology Co., Ltd. was selected as a representative of ordinary phosphorus removal agents to discuss the phosphorus removal effect of high-efficiency phosphorus removal agents.

[0053] Take 6000mL of electroplated iron plate water as sewage water sample, and carry out phosphorus content detection and phosphorus removal test in sewage. Determination - ammonium molybdate spectrophotometric method as standard. The total phosphorus content of the sewage water sample was measured to be 21.7 mg / L, and the pH of the raw water was 6.5.

Abstract

The invention relates to a high-efficient phosphate removing agent, which relates to the technical field of sewage treatment, and is prepared from the following components in percentage by mass: 30 percent to 70 percent of metallic compound, 10 percent to 20 percent of natural mineral powder,10 percent to 20 percent of flocculating agent,5 percent to 10 percent of activated carbon, and 5 percent to 10 percent of coagulant aid. According to the scheme, through providing the high-efficient phosphate removing agent, through a physics-chemistry combining method, and by utilizing cooperative interaction of the components, phosphorus in inorganic and organic phosphorus wastewater can be effectively removed; the high-efficient phosphate removing agent has the advantages of simplicity in preparation, convenience in use, low cost, less dosage, quickness in reaction, superior phosphate removing effect, wide applicable range, and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency phosphorus removal agent and a preparation method thereof. Background technique [0002] Since the industrial revolution, the development and utilization of minerals has aggravated environmental pollution, and the increase and accumulation of nitrogen and phosphorus discharged from industrial and agricultural production have resulted in eutrophication of water bodies, which will cause explosive reproduction of algae and other plankton, causing massive deaths of fish and other organisms . Contaminated drinking water will pose a great threat to human health, and even cause cancer. In recent years, many lakes, reservoirs and rivers in my country have been frequently polluted, including large-scale outbreaks of blue-green algae, frequent occurrences of red tides in offshore waters, and the emergence of Enteromorpha in coastal cities. The occurrence of thes...
