Underground integrated sewage treatment system

Abstract

The invention discloses an underground integrated sewage treatment system, comprising: a water inlet pipe unit matched with an external sewage output device; a sewage treatment bucket; and a sludge treatment bucket, in which a drying component for accommodating sludge is arranged ; Wherein, the water outlet end of the water inlet pipe unit communicates with the inner barrel through the water inlet pipe, and the bottom of the outer barrel communicates with the drying assembly through the sludge pump and the sludge pumping pipe; the other end of the drying assembly passes through the discharge The outlet is communicated with the discharge bin, and the discharge bin is communicated with the external organic fertilizer storage pool through the vertical lifting assembly. The invention provides an underground integrated sewage treatment system, which can not only realize the treatment of sewage, but also carry out the treatment of the sludge produced by the buried sewage treatment barrel and the sludge treatment barrel through the cooperation of the two. The treatment realizes the secondary processing of the sludge after sewage treatment, making it a recyclable organic fertilizer, and at the same time produces corresponding economic benefits.

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.
