Weak stream river side ditch repair system with pollutant reduction and landscape utilization functions

Abstract

The invention relates to a weak stream river side ditch repair system with pollutant reduction and landscape utilization functions. The weak stream river side ditch repair system is characterized in that a sewage pipe is connected to the downstream of a river, and is connected with the water inlet end of a filler reinforcement biological treatment system; the water outlet end of the filler reinforcement biological treatment system is connected with the water inlet end of a ceramsite reed bed advanced treatment system; the water outlet end of the ceramsite reed bed advanced treatment system isconnected with the water inlet end of a wetland landscape; and a water outlet pipe of the wetland landscape is connected to the upstream of the river. The weak stream river side ditch repair system has broad market popularization prospect in small towns with financial strain, low technical levels and water shortage, and is low in running cost and high in comprehensive performance; most of processlinks are naturally formed, so that less capital investment and low running cost are required; and moreover, water body pollution abatement can be combined with a farming technology, so that the technical requirements of running and maintenance are lower, and a construction mode and management rules are simpler.

Description

technical field [0001] The invention relates to a slow-flowing river channel side ditch repair system with both pollutant reduction and landscape utilization, in particular to one, which belongs to the technical field of polluted water body repair. Background technique [0002] The traditional method of sewage treatment is to separate sewage from the environment and introduce it into a specific area to carry out human intervention measures to purify the sewage. In contrast, the remediation method of polluted water is a pollution treatment method that considers the water body and its surrounding environment as a whole, and the remediation process includes the protection of the surrounding environment. Based on the different spatial locations of project implementation, the remediation of polluted water bodies is divided into ex-situ remediation, in-situ remediation and bypass side ditch treatment. Among them, the bypass side ditch treatment method is to flow a part of the pol...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a system for repairing side ditches of slow-flowing rivers with both pollutant reduction and landscape utilization, focusing on the poor fluidity and complex pollutant components of rivers in small towns in water-deficient areas , the source of pollutant discharge is not clear and the discharge method is uncertain, the sediment pollution is serious and the conditions for dredging are not yet available, to solve the reality that small towns in water-deficient areas have a large demand for resource utilization of polluted water bodies but limited investment in treatment funds question
