Slow-release reagent adding system for drainage pipe network and using method thereof

Abstract

The invention provides a slow-release reagent adding system for a drainage pipe network. The system comprises chain type guide rails, a suspension type support, a feeder and a slow-release reagent. The chain type guide rails are installed in an inspection well and a drainage pipeline. The suspension type support is suspended on the chain type guide rails, and is connected to the feeder. The slow-release reagent is arranged in the feeder. The invention further provides system mounting, operation and maintenance method. According to the system, the internal spaces of the inspection well and thedrainage pipeline are fully utilized, the delivery and placement of the feeder filled with the slow-release reagent in the drainage pipeline are realized through the ingenious design of the chain typeguide rails and the suspension type support, and the water quality regulation and in-situ purification of the drainage pipeline are realized through the reasonable matching of slow-release reagents with different functions. Compared with the prior art, the system 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 a slow-release medicament dosing system for a drainage pipe network and an application method thereof. 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. For example, during the "Thirteenth Five-Year Plan" period, on the basis of the total length of about 9,530 km of drainage pipelines in Shanghai, about 100 kilometers of supporting drainage pipelines were built in the central urban area, and about 310 kilometers of new drainage pipelines were newly built in the suburbs. The increasingly perfect drainage pipeline system provides convenience for the transportation of various types of sewa...

AI Technical Summary

Problems solved by technology

[0003] These problems are mainly manifested in: 1) The acidic or alkaline wastewater received by the drainage pipes, and the industrial wastewater containing oxidizing substances are easy to corrode the pipes; 2) The oily substances in the drainage pipes are difficult to dissolve in water and are easy to stick On the pipe wall, dirt that is difficult to wash is formed, causing the pipe to be blocked; 3) Harmful microorganisms (such as: iron bacteria, sulfur bacteria) that grow in the drainage pipe can easily cause corrosion and blockage of the pipe and related equipment; 4) Organic waste in the drainage pipe Anaerobic hydrolysis of polluted wastewater can produce a large amount of toxic, flammable and explosive gases (such as: carbon monoxide (CO), hydrogen sulfide (H 2 S)), the accumulation to a certain extent can cause poisoning or explosion in case of open fire; 5) Mosquitoes, flies, cockroaches and other vectors are easy to breed in drainage pipes or inspection wells, endangering human health

[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.
