Abstract

The invention discloses a wastewater comprehensive treatment method. The method comprises the following steps: performing former treatment of domestic wastewater, and adjusting the PH value of the domestic wastewater, so as to ensure that heavy metal in a dissolved state in the domestic wastewater is precipitated; performing former treatment of initial rainwater, and adjusting the PH value of the rainwater, so as to ensure that heavy metal at dissolved state in the rainwater is precipitated, and gathering suspended solids in the rainwater through a coagulation reagent; performing former treatment of domestic sewage, and degrading solid waste organism in the domestic sewage through a microbial agent; performing post comprehensive treatment, pumping treated water into a sedimentation basin, so as to be sufficiently precipitated, and ensuring that treated water meeting standards is isolated. The method can effectively remove various heavy metal ions, such as chromium, arsenic, nickel, mercury, lead and zinc ion, in wastewater, so as to enable the discharged wastewater to meet the standards, is short in technology processing flow and high in economic efficiency, has higher heavy metal removal rate, and can realize the recycling and reuse of wastewater.

Description

technical field [0001] The invention relates to a comprehensive wastewater treatment method. Background technique [0002] Common harmful heavy metal elements include chromium, arsenic, nickel, mercury, lead, zinc, etc. These heavy metals and their compounds only change in form during the process of water migration and transformation, and will not disappear. They are cumulative poisons, which are harmful to both plants and humans. Has a toxic effect. For plants, it is mainly absorbed into the plant body through plant roots. Excessive amount will directly affect the growth and development of plants, and in severe cases, it will cause the plants to wither and die. For the human body, harmful heavy metals will also enter the human body through the skin and other channels, and mainly remain in the liver. , kidney, brain and other organs and tissues, when excessive, it will cause poisoning to these human organs, and in severe cases, it will cause functional damage or even comple...
