Embodiment 1

[0031] A small wetland in Linyi, Shandong Province was selected as the experimental area. The wetland is an advanced treatment wetland for the tail water of a domestic sewage treatment plant. Tail water discharge is 400m 2 / h, the winter wetland is almost unable to operate to treat the tail water. At the outlet of the tail water, Ⅰ bionic membrane aeration area, Ⅱ submerged plant purification area, Ⅲ ecological floating bed purification area and Ⅳ aquatic plant mixed planting area are arranged.

[0032] Area Ⅰ The length and width are 100×50m, the channel width is 1m, the channel spacing is 1m, the top is covered with film, and the interior is equipped with aeration pipes and bionic film. The channel is 1.5m deep and the effective water depth is 1.3m.

[0033] Part II is divided into front and back parts, each part is 100×50m in length and width, 1m in width and 1m in channel spacing, film-covered on the top, aeration tubes and bionic film hanging inside. The channel is 1.5...

Embodiment 2

[0041] A small wetland in northern my country was selected as the experimental area, and the wetland was an advanced treatment wetland for domestic sewage in a village. Before entering the wetland, go through an approximately 3000 m 2 The ponds are collected intensively, and lotus roots are planted inside the ponds, but there are almost no other aquatic plants withered in winter. After centralized collection by the pond, the sewage discharge is 50m 2 / h, Ⅰ bionic membrane aeration area, Ⅱ thermal insulation submerged plant purification area, Ⅲ thermal insulation ecological floating bed purification area and Ⅳ cold-resistant + warm-loving aquatic plant mixed planting area are arranged at the outlet.

[0042] Area Ⅰ The length x width is 50 x 40m, the channel width is 1m, the channel spacing is 1m, the top is covered with film, and the interior is equipped with aeration pipes and bionic hanging film. The channel is 1.5m deep and the effective water depth is 1.3m.

Abstract

The invention relates to the field of water purification and provides a wetland purification system for heat preservation in winter. The wetland purification system comprises a bionic biofilm culturing aeration area, a submerged plant purification area, an ecological floating bed purification area and an aquatic plant mixed plantation area sequentially arranged along the water flowing direction. The wetland purification system normally operates in northern China, the wetland plant normally grows in winter, the purification efficiency of a water body is improved by aerating and inoculating indigenous flora through bionic biofilm culturing, the purification efficiency is relatively high, the solar energy is fully utilized, and the system is simple in design and convenient in management, and is suitable for large-scale reconstruction.

Description

technical field [0001] The invention relates to the field of water quality purification, in particular to a wetland purification system for winter heat preservation. Background technique [0002] The constructed wetland system is a wetland system designed and supervised by humans for the purpose of treating sewage. It uses the comprehensive effects of soil, plants, and microorganisms in the wetland system to purify some sewage and industrial wastewater through the comprehensive effects of soil, plants, and microorganisms in the physical, chemical, and biological aspects of the wetland system. The absorption and utilization of plants themselves, the interception of plant roots, the adsorption and interception of fillers, and the action of microorganisms are used to purify sewage and some industrial wastewater, thereby improving the water quality to varying degrees. However, the operating effect of constructed wetlands is greatly affected by seasons, especially in northern Chi...
