Cosmetics wastewater treatment equipment

1Characteristics of Cosmetics Wastewater Pollution

Cosmetics can be divided into general liquid unit, cream lotion unit, powder unit, aerosol and organic solvent unit, wax based unit and other units. The basic moisturizing ingredients of cosmetics are mainly divided into plant oils, waxes, hydrocarbons, synthetic oils and fatty acids, fatty alcohols and lipids; In addition, it also contains emulsifier, thickener, antioxidant, antiseptic, bactericide and essence pigment. The main sources of cosmetics production wastewater are as follows: (1) cleaning and rinsing wastewater. (2) Process drainage during product processing. The water quality of cosmetics production wastewater is above 1700-1000mg/L COD, 500-5000mg/L BOD, 80-5000mg/L SS, 20-300mg/L animal and vegetable oils, 17-200mg/L LAS, and pH between 5-12. The main characteristics of cosmetics production wastewater are as follows: (1) The amount of wastewater is generally not large, but the concentration of pollutants is high. (2) The composition of wastewater is complex. (3) There are many biologically recalcitrant substances. (4) There are many toxic and harmful substances.

IICosmetics wastewater treatment process

The treatment process needs to be combined with high concentrations of pollutants such as COD, BOD, SS, anionic surfactants, etc., with small water volume, large changes in water quality, and intermittent discharge. The combination process technology of coagulation sedimentation+ASB+SBR is preferred.

Cosmetics process flow: industrial wastewater - grid - regulating tank - dosing device - coagulation and sedimentation - SBR tank - SBR tank - sludge concentration tank - filter press - clean water tank - sludge transportation.

IIIAdvantages of Cosmetics Wastewater Treatment Equipment

1. Strong ability to withstand impact loads, with an average residence time of over 6 hours for contact oxidation method; 2. It has the ability to remove nitrogen and phosphorus, and can achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage by adjusting the structure of the equipment; 3. The fillers in the contact oxidation tank are mostly composite soft fillers, which are lightweight, high-strength, physically and chemically stable, have a large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilm; 4. An aerator is used in the contact oxidation tank for air blowing aeration, causing the fiber bundles to continuously float and aerate evenly, resulting in mature microbial growth and possessing the characteristics of activated sludge process; 5. Stable effluent quality, low sludge production and easy treatment; 6. Submersible pumps can be installed in equipment to reduce project investment; 7. The equipment can be installed on the ground or buried underground. When buried underground, the upper cover can be used for greening, resulting in a smaller factory area and fewer ground structures; 8. Easy to achieve automatic control and simple management operation; 9. The device can be connected to a car to make a mobile integrated sewage treatment equipment.

4、 Cosmetics wastewater treatment equipment brings profits to customers

The main benefits include small capital investment and relief of pressure on municipal pipeline construction; Effectively saving construction area; Effectively realize the reuse of reclaimed water and save water; We can design buried equipment according to customer needs, and plant flowers and grass on the ground without affecting the surrounding environment.

(1) Small capital investment. The investment pressure for building large-scale sewage treatment plants is high, while the total investment for buried integrated equipment is very small, with market prices ranging from tens of thousands to hundreds of thousands, making it suitable for small-scale social capital investments such as real estate and small factories. This is also more in line with the pollution control principle of who pollutes, who governs in our country.

(2) Relieve the pressure on municipal pipeline construction. The construction of sewage treatment plants often requires the construction of large-scale municipal pipeline systems. For areas with underdeveloped pipelines such as residential areas, scenic spots, and factories, building sewage treatment plants is neither convenient nor economical. In this case, using integrated equipment is more suitable. In addition, for the diversion drainage system, smaller flow sewage can be directly discharged into rainwater pipes or water bodies after being treated by integrated equipment without increasing the pressure of the sewage pipes.

(3) Effectively save construction area. The construction of sewage treatment plants inevitably occupies a large area of land and damages the ecology. With the process of urbanization, land use is becoming increasingly scarce. The buried integrated equipment has high processing efficiency and can be buried for processing. It basically does not occupy surface area and does not affect the overall layout and environmental landscape of the building complex.

(4) Effectively achieve the reuse of reclaimed water and save water. The main obstacle for sewage treatment plants to carry out reclaimed water management is also the need to lay a large network of reclaimed water pipelines. Integrated equipment can be configured more flexibly, and usually the drainage point is also a reclaimed water reuse point, which can completely save the construction of reclaimed water channels. With the increasing demand for reclaimed water reuse in China, underground integrated equipment will demonstrate greater advantages.
