Description
Technical Field
[0001] The utility model relates to the technical field of wastewater treatment, in particular to an integrated salt-containing wastewater treatment device. Background Art
[0002] Saline wastewater refers to wastewater with a total salt content of at least 3.5wt%, which mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). Saline wastewater is produced in a wide range of ways, and it is crucial to remove the impact of organic pollutants in saline wastewater on the environment.
[0003] Reverse osmosis membrane filters, MVR evaporation concentrators, etc. are mainly used for the treatment of high-salt wastewater such as saline wastewater from chemical enterprises and desulfurization wastewater from power plants. However, the existing saline wastewater treatment devices do not have a reflux structure, and cannot return the unqualified and qualified wastewater to the reverse osmosis filter for further treatment. Therefore, an integrated saline wastewater treatment device is proposed. The wastewater treated by the reverse osmosis filter is tested by a detection component. If it does not meet the standard, it will be returned to the reverse osmosis filter through the reflux component for further treatment to ensure that the wastewater meets the treatment standard. Utility Model Content
[0004] In response to the problems in the prior art, the utility model provides an integrated salt-containing wastewater treatment device, which detects the wastewater treated by the reverse osmosis filter through a detection component. If the wastewater does not meet the standards, it will flow back to the reverse osmosis filter through a reflux component for further treatment to ensure that the wastewater meets the treatment standards.
[0005] The technical solution adopted by the utility model to solve the technical problem is an integrated salt-containing wastewater treatment device, comprising a reverse osmosis filter, an MVR evaporation concentrator is arranged on one side of the reverse osmosis filter, a connecting pipe is fixed between the MVR evaporation concentrator and the reverse osmosis filter through a flange, a detection component is arranged on the outside of the connecting pipe, the detection component comprises a pipe sleeve arranged on the outside of the connecting pipe, a pH meter is installed on the top of the pipe sleeve through a mounting seat, and a detection probe is installed on the top of the pipe sleeve located on one side of the pH meter through a mounting frame;
[0006] A first water pump is arranged at one end of the reverse osmosis filter away from the MVR evaporation concentrator, a butt joint pipe is fixed to the water inlet end of the first water pump through a flange, a reflux assembly is arranged between the butt joint pipe and the connecting pipe, the reflux assembly comprises a reflux pipe fixed between the connecting pipe and the butt joint pipe through a flange, and a second water pump is sleeved on the outer side of the reflux pipe.
[0007] By adopting the above technical scheme, the saline wastewater is treated by the reverse osmosis filter and the MVR evaporation concentrator to remove the excess salt in the wastewater. The pH meter detects the wastewater treated by the reverse osmosis filter through the detection probe. If it does not meet the standard, the second water pump will pump the wastewater into the reflux pipe to make it reflux so that the reverse osmosis filter can treat it again.
[0008] Specifically, a second valve is sleeved on one end of the return pipe close to the butt-joint pipe, and a first valve is sleeved on one end of the return pipe close to the connecting pipe.
[0009] Specifically, a water inlet pipe is fixed between the water outlet of the first water pump and the water inlet of the reverse osmosis filter via a flange, and a flow meter is connected to the top of the water inlet pipe via a threaded groove.

[0013] Beneficial effects of the utility model:
[0014] (1) The utility model discloses an integrated salt-containing wastewater treatment device. The detection probe can detect the pH value of the wastewater discharged from the reverse osmosis filter and transmit it to the pH meter for display. If the pH value of the wastewater does not meet the standard, the personnel close the third valve, open the first valve and the second valve, and turn on the second water pump to draw the wastewater in the connecting pipe after being treated by the reverse osmosis filter out of the connecting pipe, and return it to the docking pipe through the reflux pipe so that it can be transported to the reverse osmosis filter for treatment again.
[0015] (2) The utility model discloses an integrated salt-containing wastewater treatment device. The first water pump is turned on to pump out the salt-containing wastewater and transport it to the reverse osmosis filter through the water inlet pipe. Under the action of the osmotic pressure higher than the solution pressure, the reverse osmosis filter can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water by separating these substances from the semipermeable membrane because other substances cannot pass through these substances. The third water pump is turned on to pump the treated wastewater flowing into the connecting pipe to the MVR evaporation concentrator. The MVR evaporation concentrator evaporates the wastewater at high temperature to crystallize the salt in the wastewater and separate it from the water, thereby removing the salt in the wastewater and converting the water into pure water by high-temperature evaporation to meet the discharge standard or for recycling.

The pH meter 702 detects the wastewater treated by the reverse osmosis filter 1 through the detection probe 703. If it does not meet the standard, the second water pump 802 pumps the wastewater into the reflux pipe 801 to make it reflux so that the reverse osmosis filter 1 can treat it again.
