Embodiment Construction

[0014] refer to figure 1 and figure 2 , the present invention is an aeration treatment device for LAS wastewater, comprising a sludge tank 3, an aeration tank 2, a regulating tank 1, a water inlet 7 and a sewage inlet 8, a sludge tank 3, an aeration tank 2 and a regulating tank 1 Connected in turn, the sludge tank 3, the aeration tank 2 and the adjustment tank 1 are poured with concrete and made into a simple cube shape. The water inlet 7 is on the upper side of the aeration tank 2, the sewage inlet 8 is on the upper side of the sludge tank 3, the sludge pump 6 is installed on the sludge tank 3, the lift pump 4 is installed on the regulating tank 1, and the aeration tank The bottom of 2 is provided with aeration pipe network 5. The inlets of the lift pump 4 and the sludge pump 6 are respectively located at the lower part of the regulating tank 1 and the sludge tank 3 . The aeration pipe network 5 is connected with a fan, and the aeration pipe network 5 includes several air...

Abstract

The invention discloses an aeration treatment device for high LAS wastewater. The aeration treatment device comprises a sludge tank, an aeration tank, a regulating tank, a water inlet and a sewage inlet, wherein the sludge tank, the aeration tank and the regulating tank are sequentially communicated; the water inlet is positioned on the upper side of the aeration tank; the sewage inlet is positioned on the upper side of the sludge tank; a sludge pump is arranged on the sludge tank; a lift pump is arranged on the regulating tank; and an aeration pipe network is arranged at the bottom of the aeration tank. When wastewater flows through the aeration tank, a large amount of foams are generated at the aeration tank, the foams are used as a carrier according to the surface adsorption principle of foams, solutes or particles in a liquid phase can be separated, the concentration of pollutants such as LAS can be reduced, and then the foams are cleaned away; after the wastewater is aerated, lower clear liquid enters the regulating tank, and the pretreated wastewater is discharged to a subsequent treatment unit by the lift pump, so that the LAS treatment pressure of a subsequent system is practically and effectively reduced, and a large amount of foams are prevented from appearing on the liquid level of subsequent treatment equipment. The device is applied to the field of wastewater treatment.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a LAS wastewater aeration treatment device. Background technique [0002] With the continuous improvement of living standards and the continuous progress of society, cosmetics have gradually become a necessity in daily life. In recent years, the domestic cosmetics industry has developed rapidly, occupying an important position in the national economy, and showing great potential and broad prospects. The consumption of cosmetics continues to increase significantly, and the pollution caused by the production process should be highly valued. [0003] The main sources of cosmetic wastewater are as follows: 1. Cleaning and washing wastewater, such as washing water in the refining process of products or intermediate products, washing water in reaction equipment or reactors when replacing products or intermittent reactions; 2. Process drainage in product processing, such as distilla...
