Problems solved by technology

[0002] As the national environmental protection requirements are getting higher and higher, the traditional industrial wastewater treatment process requires a large investment, a large area, high treatment costs, complex system operations, and extremely unstable effluent quality. It has become increasingly unable to adapt to the current environmental protection policy. needs, and the traditional industrial wastewater treatment process uses large-scale civil engineering facilities, which are not easy to relocate

Abstract

The invention provides a wastewater zero emission device. The wastewater zero emission device comprises a water collection tank, an electric flocculation tank, a sedimentation tank, a filtering system, an ultrafiltration system and a reverse osmosis system, which are connected in sequence through a pipeline, wherein the water collection tank is connected with a water inlet pipe; each of the ultrafiltration system and the reverse osmosis system is provided with a wastewater outlet pipe; the wastewater outlet pipes are connected with the water collection tank and the reverse osmosis system is provided with a water outlet pipe. A wastewater zero emission technology comprises the wastewater zero emission device. By adopting the wastewater zero emission device and technology, provided by the invention, the aims of reduction of the wastewater treatment cost and equipment investment cost and convenient moving are realized; meanwhile, the water quality of output water is improved.

Description

technical field [0001] The invention belongs to the field of industrial wastewater treatment, and in particular relates to a wastewater zero discharge device and process. Background technique [0002] As the national environmental protection requirements are getting higher and higher, the traditional industrial wastewater treatment process requires a large investment, a large area, high treatment costs, complex system operations, and extremely unstable effluent quality. It has become increasingly unable to adapt to the current environmental protection policy. needs, and the traditional industrial wastewater treatment process uses large-scale civil engineering facilities, which are not easy to relocate. Therefore, how to solve the above problems has become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a waste water zero discharge device and process, realize t...
