Not susceptible to plugging municipal wastewater treatment system
Technical field
The utility model relates to a kind of Sewage treatment systems, specifically is a kind of difficult obstruction, the municipal wastewater treatment system in prolongation municipal sewage system life-span.
Background technology
In a city, water drain is an important component part of a municipal administration, is to guarantee the Aorta that the city is able to turn round, and therefore, the processing of municipal wastewater must guarantee that it is difficult for stopping up and running well throughout the year, does not need frequent replacing.
In the municipal wastewater system of existing city, because the many dusts in city, leaf etc., when raining in torrents; These foreign material in city are washed in the water drain through regular meeting; Result in blockage, and in this anoxic environment of water drain, mikrobes such as anerobes can breed in a large number; Make water drain often damage, therefore must reduce this damage.
The utility model content
The municipal wastewater treatment system that the technical problem that the utility model will solve provides a kind of difficult obstruction, prolongs the municipal sewage system life-span.
The content of the utility model is to comprise water inlet pipe, the settling bowl that is connected with water inlet pipe, and the pipe that is connected with settling bowl, be connected to flocculation basin, sterilization pool and aeration tank on pipe in turn, and the rising pipe that is connected with the aeration tank.
The beneficial effect of the utility model is, the settling bowl of the utility model is used for some foreign material of sedimentation city municipal wastewater, such as leaf etc., makes it to flow in the water drain of city municipal systems, avoided needing often to remove the work of water drain foreign material.After the water of a plurality of water inlet pipes was gathered together, water entered into flocculation tank, added flocculation agent, can further know physics impurity and impurity atom, guaranteed the safety of pipe.
Through sterilization is that municipal effluent is further sterilized through sterilization pool and aeration tank then, kills anaerobion, discharges through rising pipe then.
Description of drawings
Accompanying drawing 1 is the structural representation of the bottom surface of the utility model.
In the drawings, 1 water inlet pipe, 2 settling bowls, 3 pipe, 4 flocculation tanks, 5 sterilization pools, 6 aeration tanks, 7 rising pipes.
Embodiment
Shown in accompanying drawing, the utility model comprises water inlet pipe 1, the settling bowl 2 that is connected with water inlet pipe 1, and the pipe 3 that is connected with settling bowl 2, be connected to flocculation basin 4, sterilization pool 5 and aeration tank 6 on pipe 3 in turn, and the rising pipe 7 that is connected with aeration tank 6.
The settling bowl 2 of the utility model is used for some foreign material of sedimentation city municipal wastewater, such as leaf etc., makes it to flow in the water drain of city municipal systems, has avoided needing often to remove the work of water drain foreign material.After the water of a plurality of water inlet pipes 1 was gathered together, water entered into flocculation tank 4, added flocculation agent, can further know physics impurity and impurity atom, guaranteed the safety of pipe.
Through sterilization is that municipal effluent advances step sterilization one by one through sterilization pool 5 and aeration tank 6 then, kills anaerobion, discharges through rising pipe 7 then.
