Abstract

The invention provides a method for wastewater treatment by using a mechanical compression evaporation crystallizer system and belongs to the technical field of industrial wastewater treatment. A storage tank of the mechanical compression evaporation crystallizer system is connected with a balance tank which is connected with a tubular preheater, the tubular preheater is connected with an evaporation separation crystallization device and a condensation water tank, and the evaporation separation crystallization device is connected with a centrifugal separator which is connected with the storage tank. The treatment method includes: pretreated wastewater is pumped in the storage tank and enters a heat exchanger to perform heat exchange after buffering of the balance tank, material temperature rises by 5-8 DEG C, the wastewater enters the evaporation separation crystallization device to be evaporated and crystallized, high-speed separation is performed on crystal mush in a centrifugal machine, separated saturated solution returns to the evaporation crystallizer system again to be evaporated, and separated solid particles are packed. The method for the wastewater treatment by using the mechanical compression evaporation crystallizer system achieves effects regulated by the state of zero emission, circular economy and waste recovery, and evaporated distilled water can achieve the national first class discharging standard.

Description

technical field [0001] The invention belongs to the technical field of industrial waste water treatment, and relates to a method for treating waste water by using a mechanical compression evaporation crystallizer system. Background technique [0002] Drilling wastewater is the product of drilling fluid, production fluid, groundwater or crude oil mixed with production anhydrous. Its composition, properties and hazards are related to the type of drilling fluid and the composition of treatment agents. The main sources include mechanical sewage, flushing sewage, drilling fluid Sewage, operational sewage (sewage generated from downhole operations such as cementing, fracturing and acidification, workover, and well washing). Drilling sewage and waste mud in oil and gas fields have become the main sources of pollution in the oil and gas industry. If these pollutants are not effectively treated, they will pollute the soil, surface and groundwater, and cause serious impact and damage...
