Building sewage treatment system

Abstract

The invention discloses a building sewage treatment system. The building sewage treatment system comprises a reactor I, a reactor II and a reactor III, which are sequentially connected with one another. By utilizing a chemical treatment way, a flocculating agent, a sterilizing agent, a decoloring agent, a denitrition and dephosphorization agent, a deodorizing agent and the like are respectively charged into the sewage to be stirred, flocculated and precipitated, precipitated solids are compressed by virtue of a pressure chamber to form sludge with low water content, the sludge is bagged to be transported to a refuse landfill or to be secondarily biochemically treated, liquid naturally flows out by utilizing the water level height difference and enters an urban rainy water discharging pipe network, the escaping, overflow, dropping and leakage problems of the sewage pipe network can be solved; the internet technology also can be utilized to realize the centralized management remote monitoring of the building sewage treatment system, and the problem that the requirement of the biochemical treatment later management technology is high can be solved.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a building sewage treatment system. Background technique [0002] At present, there are two ways of urban sewage treatment: one is to directly use the grid tank, hydrolysis tank, sedimentation tank, sludge tank, clear water tank, adjustment tank, etc. for sewage pretreatment, and then use biotechnology for biochemical treatment; the other One is to use the urban drainage pipe network to discharge the sewage to the sewage treatment plant for centralized treatment. [0003] The biochemical treatment of building sewage has the following difficulties: [0004] 1. The composition of sewage changes greatly, especially the oil composition and fiber content in sewage. [0005] 2. The sewage flow rate changes greatly, the sewage discharge volume is the largest during the peak period, and the sewage discharge volume is close to zero during the low peak period; [0006] 3. In the process o...

AI Technical Summary

Problems solved by technology

[0004] 1. The composition of sewage changes greatly, especially the oil composition and fiber content in sewage.

[0005] 2. The sewage flow rate changes greatly, the sewage discharge volume is the largest during the peak period, and the sewage discharge volume is close to zero during the low peak period;

[0006] 3. In the process of sewage treatment, it is difficult to control the content of biological bacteria used to treat sewage, which affects the quality of sewage treatment;

[0007] 4. During the operation of sewage biochemical treatment, management technology requirements are relatively high, and it is difficult for general property management companies to master management technology

[0008] Utilize the urban sewage collection pipe network to centrally collect the sewage and send it to the sewage treatment plant for centralized treatment, which requires a large amount of sewage pipe network construction. Due to the change of the foundation of the pipe network and the reasons of the pipe network itself, it is easy to cause the sewage in the pipe network to leak out. Thus polluting the soil and groundwater in the area where the pipe network is located
