Intelligent industrial wastewater treatment system using modified attapulgite

Abstract

The invention discloses an intelligent industrial wastewater treatment system using modified attapulgite. The intelligent industrial wastewater treatment system comprises a main pipeline, branch pipelines, filter tanks, sludge discharge pipes and a sludge tank. The main pipeline is connected with the four branch pipelines, the tail ends of the branch pipelines are connected with the filter tanks, the interiors of the filter tanks are of a hollow structure, openings are formed in the two ends of the filter tanks, the lower end openings of the filter boxes are connected with the upper ends of the sludge discharge pipes, and sludge discharge mechanisms are mounted in the sludge discharge pipes. An attapulgite filter element is used for filtering wastewater, and filtered impurities are attached to the inner wall of the filter element or fall into the sludge discharge pipes. When a flow velocity sensor detects that the flow velocity is reduced to a set value, the sludge discharge mechanisms are started, wastewater injection is stopped, purified water is sprayed out through water spray holes, the inner wall of the filter element is subjected to spray washing, spiral blades are rotated through motors to move sludge downwards into the sludge tank, and water in the sludge can be reused after being filtered. The service life of the filter element is prolonged, the input cost of the filter element is reduced, and the wastewater treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically relates to an intelligent industrial wastewater treatment system using modified attapulgite. Background technique [0002] Industrial wastewater (industrial wastewater) includes production wastewater, production sewage and cooling water. pollutants. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater contains Contains various pesticides, etc. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. There...

Problems solved by technology

[0005] The purpose of the present invention is to provide an intelligent industrial wastewater treatment system using modified attapulgite, which solves the problem that the attapulgite filter element is used to fine-filter the sewage, and impurities in the wastewater will remain in the attapulgite filter element during the filtration process. The inner wall is blocked and blocked, and the blocked filter element needs to be replaced before it can be used again, resulting in a certain waste. At the same time, the operation of replacing the filter element is cumbersome, which affects the efficiency of wastewater treatment, and meets the actual use needs.
