Industrial wastewater treatment device and method

Abstract

The invention discloses an industrial wastewater treatment device which comprises a wastewater treatment box, a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are communicated with the internal space of the wastewater treatment box. The industrial wastewater treatment device further comprises at least two partition plates. The water inlet pipe and the water outlet pipe are arranged on the box body side walls on the two opposite sides of the wastewater treatment box respectively. The partition plates are arranged in the space, between the water inlet pipe and the water outlet pipe, inside the box. The partition plates divide the internal space of the wastewater treatment box into at least three water grooves. Overflow ports are formed in the partition plates. The overflow ports in every two adjacent partition plates are staggered. A filter device is arranged in each overflow port. The upper portion of each water groove is provided with an oil contamination scraping device. According to the industrial wastewater treatment device, the vast majority of oil contamination suspended matter and solid particle impurities in industrial wastewater can be removed, and the treated industrial wastewater can be directly drained on the condition of not considering other environmental protection factors.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater treatment device and an industrial wastewater treatment method. Background technique [0002] In industrial production processes such as plate production, mechanical processing, and electronic product manufacturing, a large amount of industrial wastewater containing solid particle impurities and oily suspended matter will be produced. If the industrial wastewater with oil pollution is discharged into the water body, the oil pollution will cover the water surface and prevent the oxygen in the air from dissolving into the water. The low oxygen content in the water body will hinder the photosynthesis of aquatic plants and cause the death of aquatic animals due to hypoxia. When oily wastewater enters the soil, under the action of soil adsorption and filtration, an oil film layer will be formed in the soil, making it difficult for the a...

Problems solved by technology

This device can remove a large amount of oil stains and solid impurity particles in industrial wastewater, but because the cylindrical filter element rolled by stainless steel wire mesh and non-woven fabric is used as the second-stage filter device, there is a case of filter element clogging, so it is not suitable for large quantities treatment of industrial wastewater

[0007] In summary, the existing industrial wastewater treatment devices all have the technical problems that the amount of industrial wastewater to be treated is small, and the filter device is easily blocked, which cannot meet the needs of a large amount of industrial wastewater treatment. Due to the existing industrial wastewater treatment Insufficient capacity, the industrial wastewater of many industrial and mining enterprises is directly discharged
