Energy-saving and environment-friendly heavy metal sewage treatment device

Abstract

The invention relates to the technical field of sewage treatment, and discloses an energy-saving and environment-friendly heavy metal sewage treatment device which comprises a water purifying tank, asettling tank, a stirring tank, a stirring motor, a water inlet pipe A and a water inlet pipe B. According to the energy-saving and environment-friendly heavy metal sewage treatment device, the waterpurifying tank, the settling tank and the stirring tank are arranged; heavy metal sewage is sequentially filtered by the water purifying tank and the settling tank, and the effect of triple purification of the heavy metal sewage is achieved; through arrangement of an adjusting rotary table, the rotation condition that a conical bevel gear A is meshed with an adjusting gear B and a conical bevel gear B is meshed with an adjusting gear A is realized; a stirring device and a paddle board are arranged, so that the stirring device drives the paddle board to swing in the stirring box cavity in an annular and up-and-down fluctuating mode, and the combination efficiency of heavy metal and a treating agent is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving and environment-friendly heavy metal sewage treatment device. Background technique [0002] With the development of modern society, the amount of sewage containing heavy metal ions is increasing. Direct discharge will not only pollute the environment such as water sources and soil, but also enter the human body through the food chain, causing harm to human health. [0003] However, the heavy metal sewage treatment device of the prior art generally has a fixed filtering method, a single filter from the primary filter box to the secondary filter box, multiple and unique filtering, extending and increasing the filtering device to achieve a good filtering effect, so that It will lead to an increase in filtration cost, and continuous circulation and energy-saving and environmental protection filtration cannot be achieved. Therefore, in view of the above prob...
