Embodiment Construction

[0010] Take the establishment of a landscape park on the edge of Dianchi Lake in Kunming as an example:

[0011] The total land area of ​​the project area is about 275 hectares, and the entire project area is basically rectangular. A composite artificial wetland system of about 200 mu will be built to treat domestic sewage in the landscape park and some river water near the landscape park (class IV or inferior V surface water) .

[0012] 1. Biomass Energy Conversion Center

[0013] It mainly treats the drainage of toilets and kitchens in the wetland park area and the plant waste generated in the area, and the design treatment capacity is 500m of domestic sewage 3 / d, adopt adjustment → oil separation → anaerobic → aerobic → sedimentation process, after the effluent reaches the secondary standard of "Integrated Wastewater Discharge Standard", it will enter the constructed wetland pretreatment unit for advanced treatment. Considering the impact of residential area landscape an...

Abstract

The invention relates to a purifying art for a water system in a landscape park. Surface water is delivered through a sand basin (3) and then to an oxidation pond (4) with filler, the water then flows into an artificial swamp (1), and the water which flows out of the artificial swamp is regulated and deposited by a stabilizing pond (5), finally the water flows into the water pond of the landscape park; the water is pumped into a stream swamp (2) of the park by a pumping device (6), the water in the stream swamp is pumped to a mudflat swamp (7), thus the water in the mudflat swamp can automatically flow back to the water pond of the landscape park; the domestic sewage in the landscape park is treated in the biomass energy transforming center and then is delivered into the oxidation pond (4) with filler. The biomass energy transformation includes the procedures of adjusting, oil separation, anaerobic reaction, aerobic reaction and depositing; the biomass energy transformation is mixed with the common domestic sewage after two grades of anaerobic reactions. The invention can assure the water quality in the landscape park to be equal to or better than the water quality for entertainment in the landscape park; the treatment procedure can protect environment, thereby providing satisfactory water source for an artificial lake as well as effectively treating the waste; and the invention can provide the needed energy for the whole treatment system and have great social and economic benefits.

Description

technical field [0001] The invention relates to a water system purification process of an artificial lake, in particular to a water quality purification process for a large-capacity water body landscape park. Background technique [0002] In recent years, with the improvement of people's living standards, a hydrophilic living environment has become a major demand, and the number of landscape parks has continued to increase. Water-related issues such as water supply, water purification costs, and post-management have gradually emerged, especially in landscape parks. The management of artificial lakes has not been well resolved. At present, the treatment of artificial lakes mainly adopts water diversion, circulation filtration, microbial methods, ecological water purification and other methods. Water diversion and water exchange are only suitable for small water bodies due to the consumption of a large amount of water resources; circulating filtration is a direct application ...
