Problems solved by technology
[0002] At present, due to the excessive discharge of sewage and other environmental problems, with the development of society and economy, the people's awareness of environmental protection is constantly increasing, and the country's requirements for environmental protection are becoming more and more stringent. Emission reduction work has reached the point of no delay, otherwise, it will seriously hinder the sustainable development of social economy

Embodiment Construction
[0021] figure 1 As shown, it relates to an artificial quick-seepage sewage treatment system, which is mainly composed of a pretreatment unit, an artificial quick-seepage treatment unit and a post-treatment unit.
[0022] 1. Preprocessing unit
[0023] If the CRI system (Constructed Rapid Infiltration Technology, referred to as the CRI system, the same below) contains a large amount of inorganic and organic particles in the influent, directly dosing the sewage into the quick-seepage tank will cause the quick-seepage tank to be blocked and fall. Increased dry time, reduced hydraulic load, etc. In order to give full play to the advantages of the artificial quick infiltration system, check the particulate matter and reduce the load of other pollutants, a pretreatment system is usually set up before the sewage enters the quick infiltration tank. CRI systems generally use coagulation sedimentation process, composite hydrolysis process and improved A2O process as pretreatment units...

The present invention discloses a sewage treatment method using artificial fast seepage. The sewage treatment method comprises that S1, domestic sewage enters a grid pool, and large-block floating substances in the sewage are separated and removed by the grid pool; S2, the obtained sewage enters a sand precipitation pool, and the sand particles in the sewage are removed by the sand precipitation pool; S3, the obtained sewage is discharged into a coagulation pool, and is subjected to coagulation treatment with the coagulation pool; S4, the obtained sewage is discharged into a primary sedimentation pool, and mud-water separation is completed by the primary sedimentation pool; S5, the sewage is discharged into a pre-aeration pool, and aeration is performed by the pre-aeration pool so as to increase the concentration of dissolved oxygen in the water; S6, the sewage water is distributed by a water distribution system, and the obtained material is discharged into an artificial fast seepage pool; S7, the effluent is discharged into a disinfection pool, and is subjected to ultraviolet disinfection by the disinfection pool; and S8, the effluent achieves the discharge standard, is discharged into an effluent pool, and is discharged into a receiving water body through a total discharging port. The sewage treatment method of the invention has advantages of simple process, high hydraulic load of the system, low investment and operation cost, short construction period, and good effluent effect.
Description
technical field [0001] The invention relates to a method for treating artificial quick seepage sewage, which belongs to the technical field of sewage treatment. Background technique [0002] At present, due to the excessive discharge of sewage and other environmental problems, with the development of society and economy, the people's awareness of environmental protection is constantly increasing, and the country's requirements for environmental protection are becoming more and more stringent. Emission reduction work has reached the point of no delay, otherwise, it will seriously hinder the sustainable development of social economy. [0003] The meaning of sustainable development is "development that meets the needs of the present without compromising the needs of future generations." This definition is recognized around the world. The core of sustainable development is economic development, and economic development is an irreversible inevitable trend. In order to meet the ...
