An aerobic artificial wetland winter unsupported heat preservation system for treating oil production sewage

Abstract

The invention relates to an aerobic constructed wetland winter unbraced insulation system for treating oilfield produced wastewater, which comprises insulation shed bodies, fixing ground bolts and an aerating apparatus. The insulating shed bodies are insulating films; the insulating films cover the upper surface of an aerobic constructed wetland; the edges of the insulating films are fixed below the water surface at the edge of the aerobic constructed wetland by the fixing ground bolts; the parts of the insulating films, which are above the water surface, are provided with vent holes; the aerating apparatus comprises an aerator pipe and an air pump; the aerator pipe is arranged under the water surface of the aerobic constructed wetland; and the air pump is connected with the aerator pipe. According to the invention, the aerating apparatus is adopted to fill air into the insulating films, so that the insulating films cover the space above the wetland which needs to be subjected to heat preservation, an air insulating layer is formed between the wetland and the cold air outside a shed and a heat preservation effect is achieved; and moreover, a bracket is not adopted, so that the span of an insulation device can be ensured and the defect of small span of an existing insulating shed is overcome.

Description

technical field [0001] The invention relates to an aerobic artificial wetland winter unsupported heat preservation system for treating oil production sewage, belonging to the technical field of artificial wetlands. Background technique [0002] As a new type of ecological sewage purification and treatment method, artificial wetland has developed rapidly in recent years because of its low construction cost, low operating cost, and its own landscape effect, which is easy to be accepted by the public. [0003] Constructed wetlands in a broad sense can include pond wetlands, ecological ditches, fish ponds, reservoirs, surface flow wetlands, vertical flow wetlands, subsurface flow wetlands, etc. Pond wetlands can be further divided into anaerobic ponds, facultative ponds, aerobic ponds, aerated Pond and so on. In addition, there are anaerobic and aerobic zones in wetlands. [0004] However, due to the influence of temperature and climate in winter, it cannot operate normally, e...

AI Technical Summary

Problems solved by technology

[0007] This technical solution uses ordinary greenhouses as thermal insulation means. Although it can achieve thermal insulation effect, due to the limited span of greenhouses, only small artificial wetlands can be used, which restricts the amount of sewage treatment.
