Integrated waste liquid treatment device for oily industrial wastewater treatment equipment

Integrated waste liquid treatment device for oily industrial wastewater treatment equipmentIt is an equipment used to treat oily industrial wastewater, mainly applied in industrial fields such as petroleum, chemical, and machinery manufacturing. These devices use various technological methods to remove oil and other harmful substances from wastewater, ensuring that the discharged water quality meets environmental standards. Next, Zhongke Huarui will provide you with a detailed introduction to the device.

Main purpose and processing objects

Oil containing industrial wastewater treatment equipment is mainly used to treat oil containing industrial wastewater, which mainly comes from industries such as petroleum extraction, petrochemicals, and machinery manufacturing. The oil substances contained in wastewater include suspended oil, dispersed oil, and emulsified oil, which cause serious pollution to water bodies and ecological environments.

Main types and principles

Oil containing industrial wastewater treatment equipment mainly includes the following types:

Physical treatment: Remove suspended solids and oil substances through precipitation, filtration, adsorption, and other methods. For example, fiber ball filter and walnut shell filter are used for filtering and adsorbing oil substances.

Chemical treatment: The use of chemical reagents to react with harmful substances in wastewater, converting them into harmless or low toxicity substances. Common chemical treatment methods include neutralization, oxidation, reduction, etc.

Biological treatment: utilizing the metabolic processes of microorganisms to decompose organic matter. Biological treatment methods include activated sludge process and biofilm process.

Air flotation method: By generating tiny bubbles that adhere to oil droplets, causing them to float to the surface of the water, oil-water separation is achieved.

Emulsification method: By adding chemical reagents to disrupt the stability of emulsified oil, it condenses into large particles for easy separation.

Typical equipment and its working principle

Floating oil separator: Separate floating oil through buoyancy, suitable for wastewater with high oil content.

Coagulation device: Adding coagulants to coagulate emulsified oil and suspended solids into large particles for subsequent separation.

Bioreactor: Utilizing microorganisms to decompose organic matter and remove COD and BOD.

Adsorption tower: using activated carbon and other adsorption materials to remove residual oil and organic matter.

Box type filter press: used for filtering and dehydrating sludge.

Application scenarios and effect evaluation

Oil containing industrial wastewater treatment equipment is widely used for high standard water treatment, circulating water treatment, and wastewater recycling in industries such as petroleum, chemical, and machinery manufacturing.
