Embodiment Construction

[0024] In order to achieve the purpose of using the urban sewer system to treat domestic sewage, domestic garbage, and produce biogas, the sewer system must undergo the following necessary and feasible technological transformations to meet the needs of anaerobic microorganisms to digest and degrade organic pollutants Conditions, and the advanced technology related to improving the efficiency of anaerobic digestion and degradation can be applied in the transformation. The specific modification plan and functions are as follows:

[0025] 1. Comparison of process flow before and after transformation

[0026] ①The sewer process before renovation: the sewage from the road outlet flows into the sedimentation tank; the sewage from the indoor sewage outlet flows into the septic tank; then flows into the sewer main pipe, and finally discharges to the ground.

[0027] ②Anaerobic treatment process of the sewer after transformation: the water from the pavement drain flows into the sedime...

Abstract

A method and apparatus for reforming the sewer in order to anaerobically treat life sewage and garbage and recover marsh gas features that the sewage is discharged sewag from deposition pool and septic tank via regulating pool to fermenting pool, the garbage is directly fed in fermenting pool, the acidic liquid flows from fermenting pool into pH regulating tank and then in methane generating pool, and the generated marsh gas is stored after washed by lime milk. Its advantages are low cost and high effect.

Description

Technical field: [0001] The invention relates to a sewage discharge treatment method of a sewer pipeline system, in particular to a method and device for anaerobic treatment of domestic sewage, garbage and biogas recovery. Background technique: [0002] Urban domestic sewage and domestic garbage have brought more and more serious pollution to the environment, and have become the world's pollution hazard with the widest scope and largest amount of pollution in the world. In order to control pollution, people have studied many methods, such as physical methods, chemical methods, physical chemical methods, biological treatment methods, etc. for sewage treatment. Landfill method, incineration method, composting method, comprehensive method of resource utilization, etc. to deal with domestic waste. These methods can reduce the pollutants that have been formed, but the construction of water treatment plants and domestic waste treatment plants requires time and a large amount of c...
