Solid-liquid separation waste water treatment device

Abstract

The invention relates to a solid-liquid separation waste water treatment device. The device comprises a first liquid drawing pump, a filter, a heavy metal sedimentation tank, a second liquid drawing pump, an acid-base neutralization tank, a third liquid drawing pump, an evaporator and a cooler. Waste water is extracted by a water inlet of the first liquid drawing pump, a water outlet of the first liquid drawing pump is communicated with a water inlet of the filter by a pipe, a water outlet of the filter is communicated with the heavy metal sedimentation tank by a pipe, a water inlet of the second liquid drawing pump is communicated with the heavy metal sedimentation tank, a water outlet of the second liquid drawing pump is communicated with the acid-base neutralization tank by a pipe, a water inlet of the third liquid drawing pump is communicated with the acid-base neutralization tank, a water outlet of the third liquid drawing pump is communicated with the evaporator by a pipe, the evaporator and the cooler are communicated by a pipe, a ceramic membrane is arranged between the water outlet of the filter and the heavy metal sedimentation tank and the ceramic membrane is coated with a nanometer TiO2 photocatalysis material. Compared with the existing waste water treatment device, the solid-liquid separation waste water treatment device can realize solid-liquid separation, condensation and purification, adsorb heavy metals, and eliminate excess nitrogen and phosphor elements.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a waste water treatment device capable of solid-liquid separation. Background technique [0002] With the rapid development of industry, groundwater, surface water, lakes and rivers, and landscape water have been polluted to varying degrees. The water quality of rivers and lakes has deteriorated, landscape water has turned black and smelly, algae have grown, and aquatic animals and plants have died in large numbers. The reasons for the sharp decline in landscape water quality are: sufficient nutrients such as total nitrogen and total phosphorus in landscape water; relatively moderate iron and silicon content; suitable temperature, light conditions and dissolved oxygen content; slow water flow and water body renewal cycle long. The rapid growth of certain dominant algae leads to eutrophication, which leads to the disorder of the water ecosystem and the destruction of div...

The reasons for the sharp decline in landscape water quality are: sufficient nutrients such as total nitrogen and total phosphorus in landscape water; relatively moderate iron and silicon content; suitable temperature, light conditions and dissolved oxygen content; slow water flow and water body renewal cycle long

The rapid growth of certain dominant algae leads to eutrophication, which leads to the disorder of the water ecosystem and the destruction of diversity; moreover, the existing wastewater contains high-salt, refractory, and high-color substances. These severe environmental problems need to be solved in time. solve
