Embodiment 1

[0017] In the embodiment of the present invention, a high-efficiency sewage treatment agent is composed of the following raw materials in parts by weight: 5 parts of hemp seed, 35 parts of polypropylene resin, 80 parts of hydrogen peroxide, and 22 parts of jujube wood.

[0018] The polypropylene resin was pulverized, passed through a 150-mesh sieve, mixed with hydrogen peroxide, and heated at 50°C for 20 minutes to prepare mixture A for use. Crush hemp seeds and jujube, pass through a 60-mesh sieve, add 80% absolute ethanol with a volume concentration 10 times the mass of the two, and conduct ultrasonic treatment at 75°C for 40 minutes with an ultrasonic power of 800W to prepare mixture B. Heat and stir mixture B at 90°C until dry, then lower it to 50°C, mix it with mixture A, and stir at this temperature for 30 minutes, then raise the temperature to 70°C and continue stirring for 20 minutes, then dry at 85°C That is, high-efficiency sewage treatment agent.

Embodiment 2

[0020] In the embodiment of the present invention, a high-efficiency sewage treatment agent is composed of the following raw materials in parts by weight: 12 parts of hemp seed, 42 parts of polypropylene resin, 100 parts of hydrogen peroxide, and 32 parts of jujube wood.

[0021] The polypropylene resin was pulverized, passed through a 200-mesh sieve, mixed with hydrogen peroxide, and heated at 60°C for 30 minutes to prepare mixture A for use. Crush hemp seeds and jujube, pass through a 100-mesh sieve, add 90% absolute ethanol with 12 times the mass of the two, and conduct ultrasonic treatment at 80°C for 60 minutes with an ultrasonic power of 1000W to prepare mixture B. Heat and stir mixture B at 100°C until dry, then lower it to 60°C, mix it with mixture A, and stir at this temperature for 40 minutes, then raise the temperature to 80°C and continue stirring for 30 minutes, then dry at 90°C That is, high-efficiency sewage treatment agent.

Embodiment 3

[0023] In the embodiment of the present invention, a high-efficiency sewage treatment agent is composed of the following raw materials in parts by weight: 7 parts of hemp seed, 37 parts of polypropylene resin, 85 parts of hydrogen peroxide, and 24 parts of jujube wood.

[0024] The polypropylene resin was pulverized, passed through a 200-mesh sieve, mixed with hydrogen peroxide, and heated at 55°C for 25 minutes to prepare mixture A for use. Crush hemp seed and jujube, pass through a 100-mesh sieve, add 85% absolute ethanol with 11 times the mass of the two, and conduct ultrasonic treatment at 80°C for 50 minutes with an ultrasonic power of 1000W to prepare mixture B. Heat and stir mixture B at 100°C until dry, then lower it to 55°C, mix it with mixture A, and stir at this temperature for 35 minutes, then raise the temperature to 75°C and continue stirring for 25 minutes, then dry at 90°C That is, high-efficiency sewage treatment agent.

Abstract

The invention discloses a high-efficiency sewage treatment agent and a preparation method and application thereof. The high-efficiency sewage treatment agent is prepared from the following raw materials in pars by weight: 5 to 12 parts of fructus cannabis, 35 to 42 parts of polypropylene resin, 80 to 100 parts of hydrogen peroxide, and 22 to 32 parts of jujube wood. The preparation method comprises the steps of smashing the polypropylene resin, sieving, mixing with the hydrogen peroxide, heating, and treating so as to obtain a mixture A; smashing the fructus cannabis and the jujube wood, sieving, adding absolute ethyl alcohol, performing ultrasonic processing, heating, stirring until drying, mixing with the mixture A after cooling, and drying after heat treatment so as to obtain the high-efficiency sewage treatment agent. Biochemical oxygen demands, chemical oxygen demands, permanganate indexes, total phosphorus and total nitrogen of polluted water can be remarkably lowered under the combined action of all components, heavy metal such as fluoride, cadmium, arsenic and the like and toxic substances in the water can also be effectively lowered, and the concentration of dissolved oxygen can be obviously increased. The raw materials of the high-efficiency sewage treatment agent can be easily obtained, and the high-efficiency sewage treatment agent is low in production cost, simple to operate, can effectively treat sewage, has the advantages of quick purification speed, good effect, and environmental protection and no toxin, and has very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency sewage treatment agent and its preparation method and application. Background technique [0002] In the river dredging process, the traditional method is to use a high-pressure pump to deliver high-pressure water to the river bottom to clean the river bottom. In this way, the silt deposited at the bottom of the river will inevitably spread and pollute the river. Usually, these sewages containing a large amount of silt are pulled back to the sewage treatment plant with sludge suction trucks or tank trucks for treatment, which is expensive. If the water in a reservoir such as a swimming pool stays for a long time, blue-green algae will be produced and the water in the pool will become dirty. Therefore, the water in the pool should be purified regularly. Because the traditional method is to exchange all the water in the reservoir, it takes a long time a...
