Efficient energy-saving comprehensive water treatment equipment

Abstract

The invention discloses efficient energy-saving comprehensive water treatment equipment which comprises a domestic sewage pretreatment module, an industrial wastewater pretreatment module and a mixingtreatment module, wherein the domestic sewage treatment module comprises a grid well, an oil separation tank, a comprehensive regulation tank, an anaerobic tank, an oxidation tank and a sedimentationtank; the industrial wastewater pretreatment module comprises a grit chamber, an adjusting tank, a coagulation tank, a flocculation tank, an air floatation tank and a sludge concentration tank; the mixing treatment module comprises a middle water tank, a sand filtration tank, a carban filtration tank, an ultrafiltration device and a reverse osmosis device, wherein the sedimentation tank is communicated with the middle water tank; the anaerobic tank, the oxidation tank and the sedimentation tank are respectively communicated with the sludge concentration tank through a sludge pipeline; the ultrafiltration device and the concentration water tank are respectively communicated with the adjusting tank through a concentrated water return pipeline. The equipment is used for treating industrial wastewater and domestic sewage generated in the production process at the same time. The water treatment efficiency and the water discharge standard rate are improved, the enterprise water treatment cost is reduced, and the method is economical and practical.

Description

technical field [0001] The invention belongs to the technical field of waste water recovery and treatment, in particular to a device for integrated treatment of industrial waste water and domestic sewage. Background technique [0002] Water is one of the most precious natural resources for human beings, and it is also an important resource that human beings and all living things rely on for survival and is indispensable. The total amount of water resources in my country is quite large, but our country has a large population, and the per capita share is very poor. What is disturbing is that this limited water resource is still suffering from varying degrees of pollution, and even some places are seriously polluted. [0003] Electronic companies will produce a large amount of domestic sewage and industrial wastewater in the production process. The composition of the water body is relatively complex. If it is not treated, it will pollute the surface water if it is discharged dir...

Problems solved by technology

Moreover, industrial wastewater and domestic sewage will seep into the ground, pollute the groundwater and then pollute the crops, eventually endangering human health and causing damage to the surrounding environment

[0004] At this stage, enterprises have relatively independent treatment methods for industrial wastewater and domestic sewage, which results in high treatment costs and a large economic burden on enterprises; moreover, the treatment methods adopted are relatively rough and cannot meet the discharge standards of industrial wastewater and domestic sewage.
