Metallurgy wastewater discharge equipment

Abstract

The invention provides metallurgy wastewater discharge equipment which comprises water inlet pipes and water outlet pipes. A first reverse osmosis membrane and a second reverse osmosis membrane are arranged obliquely; the water inlet pipes are arranged from the upper end to the lower end of the first reverse osmosis membrane; connecting pipes and the water outlet pipes are arranged from the upperend to the lower end of the second reverse osmosis membrane, so that smoother isolation is achieved in a novel structure; the permeability of the first reverse osmosis membrane is set to be less thanthat of the second reverse osmosis membrane; a connecting part of an upper end mixed wastewater pipe and a first reverse osmosis device is located at the upper end of the first reverse osmosis membrane; a connecting part of a middle end mixed wastewater pipe and a second reverse osmosis device is located at the upper end of the second reverse osmosis membrane, so that the novel structure is smoothin rhythm; a return pipe is arranged between a reflux pump and a centrifuge; a lower end mixed wastewater pipe is arranged on the upper side and the lower side of the lower end of the second reverseosmosis membrane, so that the novel structure can treat and purify the wastewater for many times; and the wastewater meets environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field related to chemical production, in particular to a metallurgical wastewater discharge device. Background technique [0002] In the traditional metallurgical process, when extracting high-purity metal salts or oxides from metal minerals or industrial waste residues, some impurity elements will circulate and accumulate in the solution. In order to ensure the smooth progress of the metallurgical process, when the impurity elements accumulate to After a certain period of time, a part of the solution needs to be released to expel impurity elements. However, in the entire production process nowadays, enterprises only pay attention to the recovery rate, production cost and profit margin of the extracted metals, and do not consider the recycling of resources and environmental protection. As long as it is beneficial to the enterprise, various auxiliary materials other than raw materials are used at will, resulting in...

Problems solved by technology

However, for production wastewater with complex components, its water quality and quantity often fluctuate greatly, and the discharged water after treatment cannot meet the discharge standard, and the discharge exceeds the standard. Therefore, we propose a metallurgical wastewater discharge equipment to solve the above problems
