Wastewater treatment system and wastewater treatment process

Abstract

The invention discloses a wastewater treatment system which comprises a precipitation device (1), a filtering device (2) and a disinfection and purification device (3), a filtering agent based on activated carbon is used in the filtering device, and the precipitation device comprises a pretreatment adjusting unit, a coagulation reaction unit, a precipitation unit, a micro-electrolysis unit and an air floatation unit which are sequentially communicated through pipelines. According to the invention, the filtering agent based on activated carbon is used for treating small organic molecule pollutants, heavy metals and solid particles which are difficult to remove in sewage. The activated carbon, the kieselguhr and the zeolite are blended and dried, the activated carbon and the kieselguhr can uniformly cover the surface of the zeolite, the surface area of the sewage treatment agent is greatly increased, meanwhile, the adsorption effect of the activated carbon and the kieselguhr is fully utilized, and the treatment effect on solid particles and organic pollutants which are difficult to remove is better.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment system and a wastewater treatment process. Background technique [0002] With the rapid development of economy, the living standard of our people has been improved qualitatively. However, the improvement of economy and living standards has also brought serious damage to the natural environment, especially water resources. Every day, our country discharges a large amount of industrial wastewater and domestic sewage, which contains various organic pollutants, heavy metals, microorganisms, solid particles, etc., which brings a very heavy burden to our country's sewage treatment work. [0003] The current sewage treatment methods mainly rely on traditional processes, which require a large number of workers to maintain the equipment, and the operation and management are also very complicated. The large amount of sewage discharge in modern society a...

Every day, our country discharges a large amount of industrial wastewater and domestic sewage, which contains various organic pollutants, heavy metals, microorganisms, solid particles, etc., which brings a very large burden to our country's sewage treatment work.

[0003] The current sewage treatment methods mainly rely on traditional processes, which require a large number of workers to maintain the equipment, and the operation and management are also very complicated, and the large amount of sewage discharged in modern society also brings great challenges to the traditional treatment process.

In addition, people's improvement of the quality of daily necessities in modern society has brought a lot of packaging pollution. After these pollutants enter the water source, a large amount of hard-to-degrade solid particles, heavy metals, organic waste, and the pollution level of many waste gas and sewage It is even close to industrial wastewater, but the current domestic sewage treatment process is not effective for this type of industrial wastewater, the damage to the equipment during the treatment process is extremely large, and the amount of various water treatment agents is also very large, resulting in an increase in treatment costs.
