Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an environment-friendly sewage treatment agent which comprises the following components in parts by weight: 30-80 parts of cocoanut charcoal, 30-80 parts of bamboo charcoal, 10-20 parts of opal shale, 5-12 parts of smectite, 10-20 parts of zeolite, 10-20 parts of brucite, 20-30 parts of polymeric ferric silicate sulfate and 25-45 parts of polyaluminum ferric chloride sulfate. The sewage treatment agent has the advantages of no toxicity, low influence on operating personnel and favorable treatment effect, is suitable for various types of industrial sewage, especially has outstanding effects on chemical industry wastewater, and does not have the problem of secondary pollution after treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment agent and a preparation method thereof. Background technique [0002] Chemical wastewater is the process wastewater, cooling water, waste washing water, equipment and site washing water and other wastewater discharged in chemical production. If the waste water is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health and affecting industrial and agricultural production. The basic characteristics of chemical wastewater are: the water quality is complex, there are many by-products, and the reaction raw materials are often solvent substances or compounds with ring structures, which increases the difficulty of wastewater treatment; the pollutant content in wastewater is high, which is due to the incomplete reaction of raw materials and ra...
