Embodiment 1

[0018] A sewage treatment agent, comprising the following raw materials in parts by weight, 30 parts of activated sludge, 10 parts of hydrogen peroxide, 10 parts of sodium citrate, 14 parts of yeast, 3 parts of polyacrylamide, 3 parts of ferrous sulfate, 0.4 parts of alum share.

[0019] The preparation method of above-mentioned sewage treatment agent, comprises the following steps:

[0020] Step 1, weighing required raw materials;

[0021] Step 2, after pulverizing the activated sludge, soak in hydrogen peroxide for 10 minutes, and filter to obtain the filtrate;

[0022] Step 3, adding yeast, sodium citrate, polyacrylamide and ferrous sulfate to the filtrate and then spray-drying at 50°C to obtain the first mixture;

[0023] Step 4, mix the first mixture and alum, crush it with dry ice, and then enter the granulator for granulation to obtain a sewage treatment agent with a granulation size of 20 microns.

Embodiment 2

[0025] A sewage treatment agent, comprising the following raw materials in parts by weight, 40 parts of activated sludge, 12 parts of hydrogen peroxide, 15 parts of sodium citrate, 16 parts of yeast, 12 parts of polyacrylamide, 10 parts of ferrous sulfate, 0.4 parts of alum share.

[0026] The preparation method of above-mentioned sewage treatment agent, comprises the following steps:

[0027] Step 1, weighing required raw materials;

[0028] Step 2, after pulverizing the activated sludge, soak it in hydrogen peroxide for 15 minutes, and filter to obtain the filtrate;

[0029] Step 3, adding yeast, sodium citrate, polyacrylamide and ferrous sulfate to the filtrate and then spray-drying at 55°C to obtain the first mixture;

[0030] Step 4, mix the first mixture with alum, crush it with dry ice, and then enter the granulator for granulation to obtain a sewage treatment agent with a granulation size of 25 microns.

Embodiment 3

[0032] A sewage treatment agent, comprising the following raw materials in parts by weight, 50 parts of activated sludge, 20 parts of hydrogen peroxide, 24 parts of sodium citrate, 18 parts of yeast, 15 parts of polyacrylamide, 12 parts of ferrous sulfate, 0.8 parts of alum share.

[0033] The preparation method of above-mentioned sewage treatment agent, comprises the following steps:

[0034] Step 1, weighing required raw materials;

[0035] Step 2, after pulverizing the activated sludge, soak it in hydrogen peroxide for 20 minutes, and filter to obtain the filtrate;

[0036] Step 3, add yeast, sodium citrate, polyacrylamide and ferrous sulfate to the filtrate, mix and spray dry at 60°C to obtain the first mixture;

[0037] Step 4, mix the first mixture and alum, crush it with dry ice, and then enter the granulator for granulation to obtain a sewage treatment agent with a granulation size of 30 microns.

Abstract

The invention discloses a waste water treatment agent and a preparation method thereof. The waste water treatment agent is prepared from the following raw materials in parts by weight: 30-50 parts of active sludge, 10-20 parts of hydrogen peroxide, 10-24 parts of sodium citrate, 14-18 parts of yeast, 3-15 parts of polyacrylamide, 3-12 parts of ferrous sulfate and 0.4-0.8 part of alum. The preparation method comprises the steps: weighing the required raw materials; after pulverizing the active sludge, soaking the active sludge in the hydrogen peroxide for 10-20 minutes, filtering to obtain filtrate; adding the yeast, sodium citrate, polyacrylamide and ferrous sulfate to the filtrate, carrying out mixing and spray drying to obtain a first mixture; and mixing the first mixture with alum, pulverizing with dry ice and granulating in a granulator to obtain the waste water treatment agent. The waste water treatment agent disclosed by the invention has good effect of decontamination, long service life and high practical application value.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a sewage treatment agent and a preparation method thereof. Background technique [0002] In the past few decades of economic development in China, due to neglect of environmental protection, environmental pollution is very serious at this stage. Pollution such as smog and sandstorms have seriously affected people's normal life, and even damaged our health. my country is one of the countries with the most serious environmental pollution in the world. Whether it is a city or a village, our country's atmosphere, rivers, lakes, oceans and soil are all polluted to varying degrees. [0003] In the annual sewage discharge in the country, only 10% of domestic sewage and 70% of industrial sewage are treated, and a lot of sewage is discharged to facilities without being treated to the national discharge standard, thus causing serious damage to the environment. It is very importa...
