A kind of industrial wastewater treatment method

Abstract

The invention discloses an industrial wastewater treatment method. A filtering pond is adopted for filtering; a plurality of water inlets and a plurality of water outlets of the filtering pond are provided with independent on-off valves and filter screens; the bottom of the filtering pond is composed of a plurality of flat plates capable of being overturned; a sludge tank is arranged below the bottom of the filtering pond and connected with a mud pump; after filtration, filtered wastewater is guided into an adsorption pond, and a composite adsorption material comprises a carrier and a functional component and is introduced into an ecological treatment pond comprising a filler layer and an aquatic plant layer. The unique filtering pond design is adopted, the filter screens are replaced while continuous filtering is achieved and the whole treatment process is not affected, treatment is convenient because of the sludge tank design, the components of the adsorption material are reasonably arranged, water absorption and ion adsorbing capacity are very high, a good adsorption effect is further guaranteed through ecologic treatment, and it is avoided that harmful components are leached out again after adsorption.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an industrial wastewater treatment method. Background technique [0002] Sewage treatment refers to the process of purifying sewage so that it can be discharged into a certain water area or meet the water quality requirements for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc. At present, in the process of industrialization in my country, there are a considerable number of enterprises whose production is extensive and heavily polluting, such as dyes, medicines, chemicals, smelting, electroplating and other production processes...

Problems solved by technology

However, in the treatment of industrial wastewater, the current water treatment methods have the problems of incomplete purification, complicated preparation and high cost, which seriously restrict the development of environmental protection process.
