Embodiment Construction

[0012] Construct the constructed wetland shown in Figure 2. The constructed wetland of the present invention is a vertical flow constructed wetland in form, which can be constructed into regular or irregular shapes on the ground, and the depth can fluctuate, and can also be artificially excavated to form regular or irregular shapes. , the depth can be seen depending on the terrain change, generally greater than 60cm; the perforated mud distribution pipe 1 is located above the wetland surface 2, higher than the appropriate position where the maximum thickness of the sludge layer 3 is accumulated, and the mud can be distributed at one end or evenly distributed through the pipe; the packing layer The particle size of the filler in 4 is generally fine at the top and coarse at the bottom, and can also be adjusted according to needs. Natural or artificial fillers can be used, such as furnace ash, gravel, sand, gravel, volcanic slag, construction waste, etc., and fillers with well-deve...

Abstract

The present invention relates to sewage and sludge treatment, and is especially artificial wetland ecosystem for treating sewage, sludge and percolate. The technological scheme of the present invention includes: planting phreatophyte in vertical current artificial wetland, draining sewage and sludge intermittently to the surface of the artificial wetland, making the liquid flow through the sludge layer and the wetland filling layer for effective purification before being collected in the collector pipe and drained, intercepting sludge in the surface of wetland for reducing and stabilizing, and eliminating sludge regularly for producing compost. The present invention has simple technological process, easy management, low cost and excellent sewage and sludge treating effect.

Description

technical field [0001] The invention relates to a treatment method of sewage sludge, specifically refers to a technology for treating sewage sludge and leachate thereof by utilizing an artificial wetland ecosystem, and belongs to the technical field of sewage sludge treatment. Background technique [0002] In recent decades, with the rapid development of my country's urban social economy, the construction of urban drainage infrastructure in my country has made great progress. According to the "Urban Sewage Treatment and Pollution Prevention Technology Policy" promulgated by the state in 2000, by 2010 the sewage treatment rate in key cities across the country shall not be lower than 70%. According to such a process, by 2015, the number of urban sewage treatment plants in the country will reach more than 2,000, the sewage treatment capacity will reach more than 80 million tons of sewage per day, and the sewage treatment rate will reach more than 70%, and my country's water pol...
