Description

Anti-blocking pipeline for urban sewage discharge

Technical Field

The utility model relates to the technical field of sewage discharge, in particular to an anti-blocking pipeline for urban sewage discharge.

Background

The direct discharge of sewage is always the 'culprit of water pollution', and the sewage interception nano tube is key to fundamentally treat the water environment. The sewage zero direct discharge is to cut sewage from production, living and operation activities, collect the sewage uniformly, and discharge the sewage to the external environment after reaching the standard, so that the sewage is not discharged in sunny days and no sewage is generated in rainy days.

The sewage and rainwater diversion is mainly carried out by two modes of a confluence system and a diversion system, wherein the confluence system is divided into a direct confluence system and a closure-type confluence system. The drainage system in many cities is to directly discharge washing sewage, catering sewage, domestic sewage and the like into river water through a sewer pipeline without treatment, so that the river surface source water body is seriously polluted.

The method is characterized in that the goal of zero and direct discharge of wastewater is immediately achieved when a company factory building is built, and a rain and sewage diversion pipe network is paved. The sewage pipeline needs to contain domestic sewage and kitchen sewage, is easy to block due to foreign matters, and is difficult to dredge due to the small pipe diameter of the sewage pipeline. In the prior art, the pipeline dredging method mainly comprises spring steel wire type dredging, pneumatic type dredging, hydraulic pressure type dredging and the like, and can dredge a pipeline under certain conditions, but has the following problems: the spring type dredging is adopted, so that the dredging is difficult in a sharp turning condition, the labor intensity is high, and the pipeline is easy to damage when the spring is rotated and forwards moved; when the hydraulic dredging is adopted, the pressure is limited, and when the hydraulic dredging is not adopted, water easily flows out of a water tank and becomes water in the full ground; the current vapour-pressure type dredger is difficult to dredge the condition that is not totally stifled, and its reason is that current vapour-pressure type dredger adopts rubber bowl shape structure shutoff, because rubber itself compression volume is limited, and the shutoff can not really seal, the shutoff can not adapt to the pipeline inner chamber of different shapes, and compressed air reveals from the gap easily and makes pressure decline, and artificial righting is compressed tightly when current vapour-pressure type dredger uses in addition, also can't control pressure, causes the pipeline to burst easily. In order to solve the problems, a new method for optimizing the design of the sewage discharge pipeline is required to be researched, the pipeline design and external force dredging cooperate with each other, and the pipeline smoothness is better ensured.
