Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: it introduces wastewater into the reactor, and uses additives to precipitate heavy metal ions in the wastewater. However, the entire reaction proceeds statically, relying entirely on the concentration gradient of the reaction and the diffusion reaction. The efficiency is low and needs further improvement.

Abstract

The invention discloses a treatment device and method for aluminum alloy machining wastewater, belonging to the technical field of machining wastewater treatment. The invention aims to overcome the problem of mixed precipitation efficiency. The device comprises a base, wherein a filtering mechanism and a reaction mechanism are arranged on the outer wall of the top of the base, and the reaction mechanism comprises a first top cover and a reaction tank which are fixed through a bolt. The method comprises the steps that a limiting internal thread ring is loosened to allow the filtering mechanism and the reaction mechanism to be in an open circuit state, a water valve on a liquid outlet pipe is closed, wastewater and a chemical precipitation reagent are respectively fed from a wastewater inlet pipe and a reagent feeding pipe, the motor is started, and the wastewater and the chemical reagent are fully mixed and reacted. The motor directly drives a gear ring to rotate through a sector gear or indirectly drives the gear ring to rotate through a straight-tooth full gear, so the reaction tank is driven to rotate through a rotary drum I, wastewater in the reaction tank can rotate, and a stirring effect is achieved; and thus, the mixed precipitation efficiency of a chemical reagent and the wastewater is improved.

Description

technical field [0001] The invention relates to the technical field of machining wastewater treatment, in particular to an aluminum alloy machining wastewater treatment device and a method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Waste water is produced during the machining of aluminum alloys, and the waste water is mainly produced by factories. Or the waste water and waste liquid discharged from the workshop. The waste water contains a large amount of alloy waste and heavy metal ions. If it is directly discharged, it will cause great pollution to the environment. [0003] After searching, the Chinese patent publication number is CN109796093A, which discloses a kind of aluminum alloy machining wastewater treatment device and its method, including a base, a filter ...
