Abstract
The invention provides an integrated refractory wastewater treating and reusing device and a sewage treatment method. With the device provided by the invention, the interior of an advanced oxidation reaction unit is provided with baffle plates which separate the advanced oxidation reaction unit into a plurality of reaction sections; a membrane separation component is arranged inside the last reaction section along the direction of water flow; the advanced oxidation reaction unit respectively communicates with a water inlet unit and an oxidant supply unit; and a water outlet unit communicates with the membrane separation component. In the advanced oxidation reaction unit, sewage, an oxidant and a powder catalyst undergo a contact reaction, so pollutants in the sewage are degraded, and a water phase is discharged after filtered through the membrane separation component. The device provided by the invention combines advantages of an advanced oxidation method and a membrane separation method, solves the problem of difficult separation of the powder catalyst in the advanced oxidation method by utilizing membrane separation, can well control pollution of a separation membrane at the same time, and has advantages like small occupied land area, short reaction time, low investment cost, and capability of synchronously realizing up-to-standard treating and reusing.
Description
technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an integrated refractory waste water treatment and reuse device and a sewage treatment method. Background technique [0002] In recent years, the shortage of water resources in my country has intensified, but the water pollution situation has not improved significantly, which has led the country to introduce stricter discharge standards from the policy level and actively promote the reuse of wastewater. [0003] As a major source of wastewater, industrial wastewater has the characteristics of complex components, refractory, toxic and harmful, and it is extremely difficult to deal with it in practice. Due to problems such as imperfect industrial wastewater operation and service system, inadequate supervision, and statistical limitations, the actual compliance rate of industrial wastewater discharge is far lower than the statistical data. In addition, the reuse rate of ...
