Description

Micro-power landscape type village and town sewage treatment device

Technical Field

The utility model belongs to the technical field of sewage treatment, concretely relates to oligodynamic view type villages and small towns sewage treatment plant.

Background

In recent years, rural economy in China is rapidly developed, the rural living standard is remarkably improved, but the improvement of the living environment of vast rural areas does not achieve ideal results. Because the environment protection awareness of residents in rural areas is generally thin, environment protection facilities are incomplete, the management is not in place and the like, most villages and towns do not have perfect sewage collection systems, and untreated domestic sewage in vast village and town areas is discharged randomly; untreated domestic sewage is discharged at will, so that the water quality of ditches and ponds blackens and becomes smelly, mosquitoes breed, the rural living environment is affected, and the physical health of residents is threatened. The rural domestic sewage is mainly from toilet flushing water, kitchen washing water, washing machine drainage, washing drainage and other drainage of peasants. The sewage quality has larger variation range along with the sewage source, whether the toilet is flushed or not, time interval characteristics and the like. Therefore, although the rural economy of China develops rapidly, the rural sewage treatment rate is very low, and the problem of rural water environment pollution is not optimistic.

Aiming at the treatment of sewage in villages and towns, the research of foreign scholars mainly focuses on: (1) the high-efficiency algae pond is provided and developed on the basis of the stable pond to treat pollutants, but the technology is obviously influenced by environmental factors such as temperature, climate and the like, when the temperature is too high or low, the growth of algae is inhibited to influence the treatment effect, and the water body characteristics, humus, algae and non-biological suspended matters influence the absorption of the algae to light and influence the treatment effect; (2) the new technology of efficient and continuous sewage irrigation of 'FILTER' is utilized to obtain better sewage treatment effect, but the cost of a hidden pipe drainage system is higher, so that the treatment method is influenced by the growing season of crops and the underground water level; (3) the sewage treatment method adopts a biomembrane method, a plankton method and a method combining physical, chemical and biological measures to achieve good effect, but has higher requirements on process conditions, needs professional personnel to operate and maintain, and is not suitable for the actual conditions of villages and towns in China; (4) the wetland sewage treatment system ensures that pollutants in the sewage are filtered by the wetland, absorbed by soil or converted into harmless substances by microorganisms, and has the defects of large occupied area and influence by oxygen supply, air temperature and plant growth season; (5) the distributed urban infrastructure system adopts an advanced membrane bioreactor built in a remote village without a drainage pipe network, simultaneously develops the research of sewage treatment of the undercurrent type artificial wetland, and purifies sewage by utilizing the interception action of microorganisms growing on the surface of the filler, plant roots, surface soil and the filler.

The research on the sewage of villages and towns in China starts late, the sewage treatment facility of the villages and the towns is still in the development stage, and the construction and the operation management are relatively lagged. The existing village and town domestic sewage treatment method mainly adopts processes of septic tanks, constructed wetlands, anaerobic ponds, land infiltration and the like without power or micro-power consumption. In addition, the method also comprises a rapid land infiltration method, a biological contact oxidation method, a nitrogen and phosphorus removal activated sludge method, a membrane bioreactor and the like. However, the method has certain limitations, and generally has the problems of complicated capital construction, large engineering quantity, large occupied area, low economic benefit, poor treatment effect, high requirements on process conditions and the like. And the sewage collection in rural areas is difficult, the investment of pipe networks is large, and the level of operation management personnel is not high, so the technology can not completely meet the treatment requirement of the domestic sewage of dispersive villages and towns.
