Buried-type integrated sewage treatment system

Abstract

The invention discloses a buried-type integrated sewage treatment system. The system comprises a sewage inlet pipe unit cooperating with an external sewage generation device, a sewage treatment bucketand a sludge treatment bucket internally provided with a drying assembly for containing sludge, wherein the sewage outlet end of the sewage inlet pipe unit is communicated with an inner bucket through a sewage inlet pipe, and the bottom of an outer bucket is communicated with the drying assembly through a sludge pump and a sludge pumping pipe; the other end of the drying assembly is communicatedwith a discharging chamber through a discharging port, and the discharging chamber is communicated with an external organic fertilizer storage pond through a perpendicular lifting assembly. Accordingto the buried-type integrated sewage treatment system, through cooperation of the buried-type sewage treatment bucket and the sludge treatment bucket, sewage can be treated, sludge generated from thesewage can also be treated, after sewage treatment, secondary processing treatment for the sludge is achieved so that the sludge can become a recyclable organic fertilizer, and meanwhile, the corresponding economic benefits are generated.

Description

technical field [0001] The invention relates to a system for use in environmental pollution treatment situations. More specifically, the present invention relates to an underground integrated sewage treatment system used in the environment treatment of scattered polluted areas. Background technique [0002] At present, mature sewage treatment technologies are divided into activated sludge method and biofilm method, and many technological processes are derived from engineering, such as A / 0, A 2 / 0 process, IFAS process of biofilm method, and A / 0-IFAS process of combining activated sludge and biofilm method. [0003] Traditional sewage treatment equipment and processes are attached Figure 1-4 As shown, according to the above process, the sewage before its treatment needs to be treated with the sewage after the first level of pretreatment (blocking and removing floating matter, sedimentation, etc.). Based on the existing relevant reports, the A / 0-IFAS process can combine the ...

Problems solved by technology

[0008] In order to meet these requirements, although the equipments of patent No. 200920022699.6 and patent No. 201120152594.X have solved some of the above problems, they cannot solve the problem of not requiring professional technicians to be on duty and maintain them. Specifically, 201120152594.X is only an anti-A / 0 process , there is no IFAS process; when the amount of sewage and pollutants fluctuate, the treatment effect is poor; and although the A / 0-IFAS process is adopted in 200920022699.6, the biological filler carrier used in the inner barrel is a suspended hollow ball. During aeration, The biological filler balls will be hit by the agitating aeration pan, break and sink into the sludge area. After running for a period of time, as the suspended hollow balls continue to break, not only the IFAS effect cannot be achieved, but the suspended hollow balls need to be manually removed by shutting down and opening the cover Fragments, increasing maintenance and re-implantation costs

[0009] In addition, these technologies can only treat sewage into dischargeable water and sludge, but there are problems in the discharge of sludge, such as on-site discharge, because of its own humidity, it will affect the environment of the place where it is discharged. At the same time, due to the problem of the treatment capacity, there is no way to carry out large-scale treatment so that it can be recycled to agricultural production. Therefore, although it has carried out sewage treatment, it has not produced any economic benefits.
