Rail type in-situ purification system for water discharge pipeline

Abstract

The invention provides a rail type in-situ purification system for a water discharge pipeline. The rail type in-situ purification system comprises a chain type rail, a suspension type bracket, a processing unit and an auxiliary unit, wherein the chain type rail is installed in an inspection well and a water discharge pipeline, the suspension type bracket is suspended on the chain type rail, the processing unit is nested in the suspension type bracket, and the accessory unit is matched with the processing unit and assists the processing unit in normal operation. According to the invention, theinternal spaces of the inspection well and the water discharge pipeline are fully utilized, the conveying and arrangement of the processing unit in the water discharge pipeline can be realized throughthe ingenious design of the chain type rail and the suspension type bracket, and the in-situ water purification, disinfection sterilization and dredging of the water discharge pipeline are realized through the flexible combination of the processing unit and the auxiliary unit; and compared with the system in the prior art, the system of the invention has the outstanding characteristics of high applicability, easiness in implementation, multiple functions, flexibility in operation, remarkable effect and the like.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to an orbital in-situ purification system for drainage pipes. Background technique [0002] Drainage pipes are engineering facilities that collect and transport urban domestic sewage, industrial wastewater and rainwater. In recent years, with the acceleration of my country's urbanization process, the number and scale of construction of drainage pipes are also increasing year by year. On the basis of the total length of about 9,530 km of drainage pipes in Shanghai, about 100 km of supporting drainage pipes in the central urban area and about 310 km of new drainage pipes in the suburbs. The increasingly perfect drainage pipeline system provides convenience for the transportation of various types of sewage and rainwater in cities and towns. However, with the gradual expansion of the drainage pipeline system, the problems of water quality pollution and secondary ...

AI Technical Summary

Problems solved by technology

[0003] These problems are mainly manifested in: 1) Harmful microorganisms (such as iron bacteria and sulfur bacteria) that grow in drainage pipes can easily cause corrosion and blockage of pipelines and related equipment; 2) Anaerobic hydrolysis of organic polluted wastewater in drainage pipes can produce a large amount of Toxic, flammable, explosive gases (such as: carbon monoxide (CO), hydrogen sulfide (H 2 S)), accumulation to a certain extent can cause poisoning or explosion in case of open fire; 3) Mosquitoes, flies, cockroaches and other vectors are easy to breed in drainage pipes or inspection wells, endangering human health; 4) If the drainage pipes have not been dredged for a long time, the Scum or sediment will easily block the pipeline and affect the normal drainage; 5) The lack of oxygen-enriched environment and aerobic microorganisms in the drainage pipeline will cause black and odorous sewage and a large amount of odor will escape from the inspection well, which will stimulate the public's senses

[0004] Faced with the above problems, the existing urban drainage pipeline system in my country still only has the capacity of transportation, but does not have the function of water purification.
