Embodiment 1

[0030] A biochemical system wastewater treatment process, comprising the following steps:

[0031] Step 1: Primary filtration: perform preliminary solid-liquid separation on the biochemical wastewater, filter out and collect the solid waste residue inside the biochemical wastewater, and use filter paper to filter the biochemical wastewater during the primary filtration, and filter the solid waste residue inside the biochemical wastewater out and collect, and pass the biochemical wastewater that has completed the primary filtration into the acid-base neutralization pool;

[0032] Step 2: Acid-base neutralization: adjust the pH value of the biochemical wastewater, and neutralize the acidic or alkaline substances inside the biochemical wastewater. When the acid-base is neutralized, first measure the pH value of the biochemical wastewater. If the result is acidic, add an appropriate dose of sodium hydroxide solution into the acid-base neutralization tank. If the measurement result...

Abstract

The invention discloses a wastewater treatment process for a biochemical system, which comprises the following steps of 1, primary filtration: carrying out primary solid-liquid separation on biochemical wastewater, filtering out solid waste residues in the biochemical wastewater, and collecting the solid waste residues, 2, acid-base neutralization: adjusting the pH value of the biochemical wastewater, and neutralizing acidic substances or alkaline substances in the biochemical wastewater, 3, oxidizing and aerating, namely aerating the aeration tank to enable the biochemical wastewater to do rotational flow motion, and removing organic matters in the biochemical wastewater, 4, sedimentation: standing the biochemical wastewater in the sedimentation tank for a certain time, and concentrating floating matters in the biochemical wastewater at the bottom of the sedimentation tank, and 5, electrodialysis: separating heavy metal ions in the biochemical wastewater from the biochemical wastewater. According to the wastewater treatment process for the biochemical system, harmful substances in the biochemical wastewater can be comprehensively removed, so that the environment is prevented from being harmed when the biochemical wastewater is directly discharged.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a wastewater treatment process for a biochemical system. Background technique [0002] Biochemical system is a general term for biological system and chemical system. It is mainly used to study the structure and function of various components in cells, such as proteins, sugars, lipids, nucleic acids and other biological macromolecules. As for chemical biology, it focuses on using methods in chemical synthesis to answer related questions discovered in biochemistry. [0003] In the biochemical system, various experiments need to be carried out, and a large amount of biochemical wastewater will be produced. There are many types of harmful substances in it. If it is discharged directly, it will cause great harm to the environment. Therefore, it is necessary to Treat it before discharge. [0004] However, the existing wastewater treatment process for biochemical sys...
