Live chain splicing type uninterrupted high-salinity wastewater purification device

Abstract

The invention provides a live chain continuous type uninterrupted high-salinity wastewater purification device. The device comprises a high-salinity wastewater adsorption treatment system and a live chain type drainage system nested in the high-salinity wastewater adsorption treatment system; the high-salinity wastewater adsorption treatment system comprises four purification area partition plates, a purification area of a hollow cylindrical structure, a cylindrical water distribution bin located at the axis of the purification area, a rotating shaft, a motor, a fixing support and a water storage tank; the positions of the four purification area partition plates are as follows: a first partition plate forms a 135-degree angle with the horizontal direction from left to right, a second partition plate forms a 45-degree angle with the horizontal direction from left to right, a third partition plate forms a 135-degree angle with the vertical direction from bottom to top, and a fourth partition plate forms a 45-degree angle with the vertical direction from bottom to top; and the four separated treatment areas are filled with hydrogel materials with a water purification effect. The device provided by the invention can realize the cyclic work of each separated treatment area, and can also achieve the effects of stirring and cleaning the filler, thereby greatly prolonging the service life of the system.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to an uninterrupted high-salt wastewater purification device with living chain connection. Background technique [0002] As the main component of industrial production wastewater, high-salt wastewater has become a major environmental protection problem faced by industrial development and wastewater treatment at the present stage due to its large discharge volume and high difficulty in treatment. [0003] Substandard discharge of high-salt wastewater will not only waste salt and water resources, but also cause serious environmental pollution. Since salinity is an important environmental factor in the water environment, it has a direct or indirect impact on aquatic organisms, growth and reproduction. When the salinity of the water environment increases sharply, it will lead to the osmotic balance between the aquatic species and its living environment, ca...

AI Technical Summary

Problems solved by technology

Biological method is a method of treating wastewater by using the metabolism and reproduction of microorganisms themselves. However, heavy metals and other substances in high-salt wastewater will destroy the life structure of microorganisms, inhibit their growth and reproduction, and even lead to cell inactivation.

The chemical method is to deal with chemicals, which is costly and will cause secondary pollution

The physical method separates some pollutants from the wastewater system by physical means such as adsorption, flocculation, coagulation, etc. Compared with the above two methods, this method is more feasible, but there are still the following problems to be solved: ① existing technology adsorption or After filtration, it needs desorption or backwashing, so it can only run intermittently. Usually, several parallel processes are set to run alternately. The essence is still intermittent operation, which increases the initial investment and operating costs; ②The quality of the adsorbent is large, which increases the total weight of the equipment. Thereby increasing the operating costs such as power consumption; ③The existing adsorbent has insufficient adsorption effect

As a new type of lightweight material, hydrogel has a good adsorption effect on pollutants, but its application in the field of high-salt wastewater treatment has rarely been reported.
