Problems solved by technology

[0003] In the current treatment devices for chemical nitric acid sewage, most of the devices neutralize the nitric acid wastewater with chemical substances and then discharge them. There are no stirring devices, vibration devices and heaters, so that the neutralization reaction is not easy. Thoroughly, so that the wastewater and sewage do not meet the discharge standards and pollute the environment

Abstract

The invention discloses a chemical nitric acid wastewater treatment device, which comprises a bottom plate, a device main body, a stirring rotation shaft, a PH sensor and a controller, wherein a support plate is arranged above the bottom plate; a fixing seat is arranged above the support plate; the device main body is arranged between the fixing seats; a fixing plate is arranged above the fixing seat; a first motor is arranged above the fixing plate; a speed reducer is arranged at the lateral surface of the first motor; a shaft coupler is arranged at one side, far away from first motor, of thespeed reducer. The chemical nitric acid wastewater treatment device has the beneficial effects that sewage can be strongly stirred through the arrangement of the stirring rotation shaft and the stirring blade, so that the neutralization reaction is fully performed; through the arrangement of a cam, a filtering net can vertically move; neutralization reaction products can be prevented from precipitation; through the arrangement of a heater, the sewage can be heated; further, the neutralization reaction can be more full, so that the discharged water can reach the discharging standard; the environment pollution is avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a chemical nitric acid wastewater treatment device. Background technique [0002] Sewage treatment is an important aspect of environmental protection. Sewage includes domestic sewage and industrial sewage, among which industrial sewage is more serious to the environment. Discharge of sewage containing nitric acid into rivers will pollute water resources and land resources, causing biological pollution in the water. A large number of deaths and devastating damage to the environment. [0003] In the current treatment devices for chemical nitric acid sewage, most of the devices neutralize the nitric acid wastewater with chemical substances and then discharge them. There are no stirring devices, vibration devices and heaters, so that the neutralization reaction is not easy. Thoroughly, the wastewater and sewage do not meet the discharge standards and pollute the environment. Conten...
