AI Technical Summary

Technical Problem

In the prior art, dust-containing acid water treatment efficiency is low, equipment area is large, investment cost and operation energy consumption are high, resulting in the purification of acid water cannot meet the requirements of subsequent treatment or reuse, and the dust-containing acid reuse is increased. Difficulty.

Method used

The pre-filtration unit is used to filter and separate the large-particle-sized suspensions in dusty acid water, and then the small-particle-sized suspensions are completely removed through the high-precision membrane filtration unit. The separated clean acid water can be directly reused or treated in the next step. The separated concentrate is separated again by circulating and excluding when the solid content of the concentrate exceeds the set value by pre-filtration.

Benefits of technology

It improves the recovery rate of acid water, reduces the load of the membrane filtration unit, extends the running time, stabilizes the filtration operation, reduces the system's land occupation, investment and energy consumption, and achieves an efficient purification effect.

Abstract

The utility model discloses a dust-containing acid water purification system which is characterized in that large-particle-size suspended matters in dust-containing acid water are filtered and separated through a pre-filtering unit, small-particle-size suspended matters in the dust-containing acid water are thoroughly removed by adopting a high-precision membrane filtering unit, and the separated clean acid water can be directly reused or subjected to next-step treatment. And after the solid content of the concentrated liquid exceeds a set value, a part of the concentrated liquid is discharged into the pre-filtering unit at the front end for pre-filtering treatment, so that the dust-containing acid water is thoroughly purified, the recycling rate of the acid water is high, the treatment efficiency is high, the energy consumption of the whole operation of the system is low, and the energy consumption is low. And the device also has the advantages of high automation degree, simplicity in operation, long service life, small occupied area and the like, and has relatively high practicability and relatively good application prospects.
