Wastewater treatment process of integrated MVR (mechanical vapor recompression) evaporation system

Abstract

The invention discloses an integrated MVR evaporation system wastewater treatment process, the top of a bottom plate is fixedly connected with a box body and a storage box, the front and back surfaces of the bottom plate are movably connected with outer sealing doors through hinges, an inner cavity of the box body is provided with a wastewater treatment device, and the top of the storage box is movably connected with a top cover through a hinge. The surface of the storage box is fixedly connected with a water pump, the output end and the input end of the water pump fixedly communicate with water pipes, and a filtering device is arranged in an inner cavity of the storage box. The wastewater treatment process of the integrated MVR evaporation system solves the problems that when an MVR evaporator wastewater treatment device is used for treating high-salinity wastewater, the wastewater amount is large, so that the treatment needs a long time, in addition, obtained salt crystals need to be manually taken out from the device, and crystals formed by salt can be adhered to the inner wall of the device, so that the equipment is inconvenient to operate, and the like. Therefore, the problem of salt crystal waste caused by the fact that the salt cannot be removed is solved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an integrated MVR evaporation system wastewater treatment process. Background technique [0002] MVR evaporator is a new type of high-efficiency and energy-saving evaporation equipment mainly used in the pharmaceutical industry. It is an upgraded product to replace the traditional evaporator. It adopts staged evaporation according to the required product concentration, that is, when the product cannot reach the required concentration after passing through the effect body for the first time, the product passes through the lower part of the effect body after leaving the effect body. The vacuum pump draws the product through the external pipeline of the effect body to the upper part of the effect body and passes through the effect body again, and then passes through the effect body repeatedly to achieve the desired concentration. [0003] In the process of industrial w...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated MVR evaporation system wastewater treatment process, which solves the need for high-salt wastewater treatment due to the large amount of wastewater caused by the existing MVR evaporator wastewater treatment device. For a longer period of time, the obtained salt crystals need to be manually removed from the device. Secondly, the crystals formed by the salt will stick to the inner wall of the device, making it impossible to remove them, resulting in a waste of salt crystals.
