Abstract

The invention discloses a municipal wastewater treatment device and method. The municipal wastewater treatment device comprises a tank body; the tank body is internally provided with a first water delivery pipe, a second water delivery pipe, a purification tank and a sedimentation tank; two ends of the first water delivery pipe are respectively connected with a water inlet pipe and the sedimentation tank; the first water delivery pipe is provided with a first wastewater interception device; an impurity grabbing mechanism is arranged above the sedimentation tank; a transportation device is arranged between the impurity grabbing mechanism and the sedimentation tank; two ends of the second water delivery pipe are respectively connected with the sedimentation tank and the purification tank; and the water inlet end of the second water delivery pipe is provided with a second wastewater interception device. The wastewater treatment method comprises the steps: mounting the pipes; mounting thefirst wastewater interception device; mounting the transportation device; mounting the impurity grabbing mechanism; mounting the second wastewater interception device; and treating wastewater. The wastewater treatment method is simple; and the wastewater treatment device is integrated into the tank body, so that not only can the occupied space be reduced, but also the cost can be reduced, and thewastewater treatment device is simple and convenient to maintain and suitable for treating municipal wastewater and also reducing the wastewater treatment pressure of a municipal pipe network.

Description

technical field [0001] The invention relates to an urban sewage treatment device and method. Background technique [0002] Urban sewage treatment refers to the measures taken to change the nature of sewage so that it will not cause harm to environmental waters. Urban sewage treatment is generally divided into three levels: primary treatment, the application of physical treatment to remove insoluble pollutants and parasite eggs in sewage; secondary treatment, the application of biological treatment to oxidize and degrade various complex organic substances in sewage into simple Substances; tertiary treatment, the application of chemical precipitation, biochemical methods, etc. to remove nitrogen, phosphorus, potassium and other refractory organic substances in sewage. [0003] The sewage treatment devices in the prior art generally occupy a relatively large area, and the construction is cumbersome. Although sewage treatment can be realized, the maintenance cost is high and th...
