Treatment device for heavy-metal industrial wastewater

Abstract

The invention relates to a treatment device for heavy-metal industrial wastewater. The treatment device consists of a solid-liquid separation tank, an intake pump, a water inlet valve, a refined filtration tank, an electrolytic tank, an evaporating tank, a calcium carbonate modified diatomite adsorption tank and a drainage valve. According to the treatment device for the heavy-metal industrial wastewater, the decolorization rate reaches up to 94% to 100%, decolorization reaction conditions are mild, and the feasibility is high; heavy-metal ions and impurities are effectively removed from water, the water is purified, the activity of biological macromolecules such as nucleic acid and protein is activated, the rate of removal of copper is 90% to 98%, and the content of copper contained in effluent water is far lower than that in primary standards of integrated wastewater discharge standard of China; the rate of removal of chromium is 98% to 99.8% and is in line with national integrated discharge standard, the equipment is simple, the effect is obvious, the rate of removal of chloroform is high, and positive influence on improvement on water quality of drinking water and guarantee of safety of the drinking water is generated; the rate of removal of ammonia nitrogen is 90% to 98%, the process is simple, the cost is low, the adsorption rate is high, the rate of removal of chromaticity is high, and thus the treatment device has a good popularization and application prospect.

Description

technical field [0001] The present application relates to the technical field of environmental protection, in particular to a heavy metal industrial wastewater treatment device. Background technique [0002] With the development of social urbanization, science and technology, and humanization, the industrial level has been vigorously developed, and more and more industrial water is used and discharged, followed by an increase in the use of environmental protection equipment and heavy metal industrial wastewater. A manifestation of the pollution problem. [0003] With the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessary to design a heavy metal industrial wastewater treatment device. [0004] Sewage treatment equipment can effectively treat heavy metal industrial wastewater in urban areas, heavy metal industrial wastewater, etc., and prevent sewage and pollutants from flowing directly into waters, which is of gr...
