Embodiment 1

[0046] The high-concentration wastewater treatment process of the embodiment of the present invention is used to simultaneously treat high-concentration acid wastewater and high-concentration alkaline wastewater. The high-concentration wastewater treatment process includes the following steps:

[0047] Dilution step: mixing high-concentration acidic wastewater and low-concentration acidic wastewater into suitable concentrated acidic wastewater, mixing high-concentrated alkaline wastewater and low-concentrated alkaline wastewater into suitable concentrated alkaline wastewater, the high concentration refers to dichromate The index is 200-500 mg / L, the low concentration means that the dichromate index is 0-50 mg / L, and the appropriate concentration means that the dichromate index is 50-150 mg / L;

[0048] Mixing step: mixing suitable concentrated acidic wastewater and suitable concentrated alkaline wastewater into comprehensive wastewater;

[0049] Wastewater pH adjustment step: a...

Embodiment 2

[0058] The high-concentration wastewater treatment line of the embodiment of the present invention is used to treat high-concentration acid wastewater and high-concentration alkaline wastewater at the same time, see figure 1 , the treatment line of the high-concentration wastewater is provided in turn according to the treatment process: a dilution pool for mixing high-concentration alkaline wastewater and low-concentration alkaline wastewater into suitable concentrated alkaline wastewater. Mixing with low-concentration acidic wastewater into suitable concentrated acidic wastewater, and then mixing the suitable concentrated acidic wastewater and the suitable concentrated alkaline wastewater into comprehensive wastewater mixing pool 5, used to add alkaline solution and / or acid to comprehensive wastewater The solution is to adjust the comprehensive wastewater to a neutral wastewater pH value adjustment tank 6. It is used to add a flocculant to the comprehensive wastewater so that ...

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a high-concentration wastewater treatment technology and treatment production line. The technology comprises the steps of diluting, mixing, wastewater pH value regulating, flocculating, clearing, precipitating and draining. According to the treatment technology and treatment production line, high-concentration acidic wastewater and high-concentration alkaline wastewater are simultaneously treated, the wastewater treatment efficiency is improved, and the wastewater treatment cost is reduced; the high-concentration acidic wastewater and low-concentration acidic wastewater are mixed into appropriate-concentration acidic wastewater, the high-concentration alkaline wastewater and low-concentration alkaline wastewater are mixed into appropriate-concentration alkaline wastewater, that is to say, the high-concentration acidic wastewater is diluted into the appropriate-concentration acidic wastewater, and the high-concentrtion alkaline wastewater is diluted into the appropriate-concentration alkaline wastewater (the concentration of the alkaline wastewater is correspondingly decreased), and then the appropriate-concentration acidic wastewater and the appropriate-concentration alkaline wastewater can be thoroughly purified in the treatment production line; the dosage of an acidic solution and/or an alkaline solution is decreased, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment process and a treatment line for high-concentration wastewater. Background technique [0002] In the prior art, acidic wastewater and alkaline wastewater are generally treated separately, which not only has low treatment efficiency but also high treatment cost. [0003] In addition, the processing capacity of the treatment line of the wastewater treatment plant is not infinite. If the concentration of acidic wastewater or alkaline wastewater is too high, for example, the dichromate index in the wastewater is 200-500mg / L, the wastewater treatment The assembly line cannot completely treat highly concentrated acidic wastewater or highly concentrated alkaline wastewater, which brings trouble to the wastewater treatment plant. Contents of the invention [0004] The purpose of the present invention is to address the deficiencies in the prior art, and provide...
