Problems solved by technology

[0005] At present, sewage treatment agents in the field of water treatment mainly include activated carbon, diatomaceous earth, activated silica gel, activated clay, polymer resin, etc., and their functions are relatively single. For example, polymer resin only acts on a specific pollutant factor. And requires frequent regeneration; single activated carbon highlights the adsorption of micropores, ignoring the role of other pores; diatomite pore size is too single

Abstract

The invention discloses an environment-friendly sewage treatment agent. The environment-friendly sewage treatment agent is prepared from the following components in parts by weight: 30 to 80 parts of activated carbon, 30 to 80 parts of bamboo charcoal, 10 to 20 parts of diatomaceous earth, 10 to 15 parts of attapulgite, 5 to 12 parts of montmorillonite, and 25 to 45 parts of polyaluminum ferric chloride sulfate, wherein the activated carbon is obtained by modifying through a hydrogen peroxide solution. The sewage treatment agent disclosed by the invention has various components and is low in cost, can effectively remove suspended solids, insoluble particles, and partially water-soluble pollutants, and simultaneously, has a good adsorption effect on heavy metal ions and aniline substances in the sewage; the sewage treatment agent is simple in component, does not have toxicity, does not have an influence on an operator, and can be applied to treating various types industrial sewage; the treatment effect is good; particularly, the environment-friendly sewage treatment agent has a most prominent effect on chemical fiber wastewater; the discharge quality of the treated sewage far exceeds the existing discharging standard; after treatment, secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment agent. Background technique [0002] According to statistics, the discharge of sewage and wastewater in my country is not only large in scale, but also growing rapidly. From 2001 to 2012, the discharge of sewage and wastewater in my country increased from 43.29 billion tons to 68.54 billion tons, with an annual growth rate of 4.86%. Urban industrial wastewater and domestic sewage are the main targets of sewage treatment plants. The urban drainage system connects the natural cycle of water and the social cycle, and the sewage treatment plant balances the water quantity and quality of the water cycle. More than 80% of the urban sewage in the country is directly discharged to nearby water bodies without any effective collection and treatment. The industrial wastewater pollution in my country is serious, causing more than 80% of the...
