Embodiment Construction

[0031] Contraction below figure 1 Further detailed description of the present application.

[0032] The examples of the present application disclose a wastewater moiety. Refer figure 1 A wastewater component process includes the following processing steps:

[0033] Wastewater classification: First, discharge copper-containing wastewater into the copper-containing wastewater treatment device by drainage tube. Thereafter, the nickel-containing wastewater that has not been processed is introduced into the treatment apparatus of copper-containing wastewater, and the pH of copper-containing wastewater is greater than 7 by the characteristics of the nickel wastewater. When the amount of nickel wastewater reached a third of the total copper wastewater, the pH of copper-containing wastewater has not reached 7 or more, the operator can add sodium hydroxide to accelerate the alkalization speed of the wastewater, Furthermore, it is easy to precipitate the copper ions.

[0034] When the pH of...

Abstract

The invention relates to a wastewater classified treatment process which comprises wastewater classified treatment: respectively treating five types of wastewater with different pollutions; tail-end wastewater treatment: mixing cyanide-containing wastewater, copper-containing wastewater and acid-alkali wastewater; performing reverse osmosis treatment on the wastewater: introducing all the wastewater into an adjusting tank, electrifying, adjusting the pH to be alkaline, and adding a flocculating agent to reduce heavy metals in the wastewater; discharge detection: discharging the wastewater into a monitoring water tank, inspecting whether each index meets the national discharge standard or not, and discharging the wastewater outwards after the indexes meet the discharge standard; if the wastewater does not meet the standard, returning the wastewater into the adjusting tank for retreatment. The process has the effects that simultaneous purification treatment of various types of wastewater is facilitated, and the safety of outward discharge of the wastewater is effectively improved.

Description

Technical field [0001] The present application relates to the field of wastewater treatment processes, and more particularly to a wastewater component treatment process. Background technique [0002] The wastewater treatment process refers to the economic, reasonable and scientific treatment of urban life sewage and industrial wastewater. With the advancement of science and technology and the continuous improvement of people's living standards, the process level of wastewater treatment is also continuously improved and improved. [0003] China Patent Publication No. CN102120660B discloses a chromium-containing ion wastewater treatment process and its equipment, including a security filter, an ion exchanger containing an H-type strong acid cation exchange resin and an ion exchanger loaded with a chromium anion exchange resin. . After the waste water is pre-filtered, the cation in the wastewater is enriched and replaced by the H-type strong acid cation exchange resin and replaces t...
