Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the present invention is further described, a kind of high-salt high-organic waste water treatment process, concrete process steps are as follows:

[0012] 1. The air is introduced into the low-temperature falling film evaporation concentrator through the fan along the air duct. The working temperature of the falling film evaporation concentrator is 50-70°C. The high-salt and high-organic waste water is introduced into the low-temperature gas-liquid falling film evaporation concentrator through pumps and pipelines , High-salt and high-organic waste water exchanges gas-liquid with air in the gas-liquid falling film evaporator, high-salt and high-organic waste water is converted from liquid phase to gas phase and enters the air to concentrate brine;

[0013] 2. After the brine is concentrated, it flows into the crystallizer through the pipeline. The crystallizer adopts the crystal seed method crystallization tec...

Abstract

The invention discloses a high-salinity and high organic matter wastewater treatment process which comprises the following steps: by means of waste low-temperature exhaust heat in a plant, at a low temperature of 50-70 DEG C, concentrating high-salinity and high organic matter substances in wastewater into solids to be collected in a gas-liquid falling film evaporator through five process steps; and converting the high-salinity and high organic matter water into evaporated vapor water, and condensing and recovering so as to recover the high-salinity and high organic matter wastewater. The process provided by the invention is low in working temperature, does not cause scale formation and can prevent corrosion, and equipment is simple and convenient to maintain, low in investment cost and small in occupied area. The process completely separates water and pollutants in the high-salinity and high organic matter wastewater, no medicaments are added in the treatment process, and residual heat is used in treatment and operation, and little power is just consumed, so that zero emission of the wastewater system is realized, the water source is saved while the environment is protected. The process is suitable for being popularized and applied to wastewater treatment in the industries such as petrochemicals and chemical engineering and the like.

Description

Technical field [0001] The invention relates to the technical field of petrochemical wastewater treatment, in particular to a high-salt and high-organic-matter wastewater treatment process. Background technique [0002] With the rapid development of my country's industry, more and more high-salt and high-organic waste water is produced in the daily production of petroleum, chemical, metallurgical and electric power industries. Due to the chemical oxygen demand (COD) index and salt content of waste water The amount is very high, which seriously pollutes the environment. The discharge of high-salt and organic-containing wastewater has brought salinization of river soil, especially industrial saline wastewater, which contains a large amount of toxic and refractory substances in addition to high-concentration salt itself. Due to the high salt content and high organic matter, these wastewaters cannot be treated by traditional biochemical methods or cannot meet the discharge stand...
