Problems solved by technology

Traditional inorganic polymer flocculants have a large dosage and serious secondary pollution; although the synthetic organic polymer flocculants have the advantages of small dosage and strong flocculation ability, they are difficult to degrade and some have certain toxic and side effects; microbial flocculants It is still in the stage of experimental research and cannot be widely used
At present, inorganic and synthetic organic polymer flocculants have been playing an extremely important role in sewage treatment, but some flocculants have simple components, slow flocculation and sedimentation speed, low turbidity removal rate, complicated use methods and secondary pollution And other issues

preparation example Construction

[0026] Such as figure 1 Shown, the embodiment of the present invention also provides a kind of preparation method of sewage treatment composite agent, comprises the following steps:

[0027] S01: Weigh each component according to the formula of the above-mentioned sewage treatment compound agent;

[0028] S02: Grinding and sieving to make the particle size of each component larger than 100 mesh.

[0029] S03: Mixing treatment to obtain the sewage treatment composite agent.

[0030] Specifically, in the above step S01, the weighing of each component can be carried out by methods and equipment commonly used in the art, and will not be repeated here.

[0031] Specifically, in the above-mentioned step S02, the processing of grinding and sieving can be carried out by commonly used equipment in the field.

[0032] Further, in the step of grinding and sieving, the particle size of each component is larger than 100 mesh, preferably 100-200 mesh. The components of the preferred siz...

Abstract

The invention provides a sewage treatment complexing agent as well as a preparation method and an application method thereof. The sewage treatment complexing agent comprises components in percentage by weight as follows: 60%-80% of a main agent, 10%-25% of a pH regulator, 5%-10% of a proportion increasing agent and 2%-6% of an adsorbent, wherein the main agent comprises at least one of aluminum sulfate, sodium carbonate and quicklime. The preparation method of the complexing agent comprises the following steps: the components are weighed respectively according to the formula of the sewage treatment complexing agent, and mixing treatment is performed to obtain the sewage treatment complexing agent. The sewage treatment complexing agent has high flocculation and sedimentation speed as well as high turbidity removal rate, can purify water efficiently, is pollution-free for natural environment and is applied to sewage treatment and landfill leachate treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage sludge treatment, in particular to a compound agent for sewage treatment, its preparation method and application method. Background technique [0002] In recent years, industrial wastewater and domestic sewage have been an important source of environmental pollution. A large amount of waste water and sewage are discharged into rivers, lakes, groundwater, etc. without treatment, which not only deteriorates the ecological environment, but also seriously threatens the life and health of animals, plants and human beings. With the strengthening of human awareness of the hazards of industrial wastewater and environmental awareness, how to deal with industrial wastewater and domestic sewage to meet the discharge standards is becoming increasingly important. [0003] At present, the main methods of sewage treatment are biochemical method, ion exchange method, flocculation sedimentation method, adsorption ...
