Abstract
The present invention relates to sewage treatment technology, and it features that domestic sewage is first treated in the pre-treating part comprising sewer well, grille well, setting tanks and pumping channel and then percolated in the percolating part comprising the first water distributing channel, the second distributing channel, water dispersing pipe and special soil. The percolated water through completely enclosed running is led to water collecting part comprising water collecting tank and centrifugal pumps and the water out of the centrifugal pumps can be used as middle water for various uses. The present invention adopts the in-situ sewage collecting, treating and reusing method, can save large amount of sewage conveying equipment and cost and save water resource. Building the underground system can protect ground environment.
Description
The invention belongs to technical field of sewage, is water treatment and water reclamation technology that sewage disposal combines with middle water recycling.
City domestic sewage is handled the mode that focuses on that adopts usually at present both at home and abroad, need cost a large amount of sewage collecting and handling charges, the general activated sludge process that adopts of municipal sewage treatment, the shortcoming of bringing is capital cost and working cost height, energy consumption is big, and pollutants removal rate such as nitrogen, phosphorus is low in the water outlet.
The objective of the invention is shortcoming, provide a kind of capital construction and working cost of making lower, save energy, the good sewage disposal technology of middle water water quality at above-mentioned existence.
The present invention is according to the practical situation of the economic condition and the northern area shortage of water resources of China, adopt processes such as pre-treatment and subsurface wastewater infiltration system to realize that effluent quality can satisfy various reuse requirements, adopt unique technique measures such as increasing thermal insulation layer and preparation special soil, can guarantee continuous operation and the result of system at north cold area.Simultaneously, screened multiple novel building equivalent material, reduced construction cost effectively, this technology can be become a reality in the popularization of China.Give the treating part based on physical process, after sewage enters subsurface wastewater infiltration system through pre-treatment, in the special soil medium, pass through physics, the chemistry and biology effect, pollutants in sewage matter is removed, thereby obtain good reuse water water quality, it is characterized in that sanitary sewage is via the cloudy well of water drain, grille well, multifeed clarifier, the preprocessing part that pressure feeding pump tank constitutes, deliver to and contain the first distribution tank, second distributes tank, water distributor, the diafiltration part that water spraying pipe and special soil constitute, cause by underground totally-enclosed operation gained water from diffusion and to have water collecting basin, water carried out various reuses during the part of catchmenting of centrifugal pump house, the water outlet of its centrifugal pump house can be used as.This reusing sewage technology has strengthened giving the processing intensity of processing, the cloudy well of its water drain, grille well are mainly removed bigger foreign material, the settling tank that is provided with reduces the pollution load in the sewage, its objective is sewage is handled in preprocessing part preferably, guarantee the effluent characteristics of subsurface wastewater infiltration system and the operation life of this system.
The present invention adopts sewage collection on the spot, on-the-spot disposal, reuse method on the spot, can save large amount of sewage handling equipment and expense, and alleviate the not enough problem of water resources.The invention belongs to the nature treatment process, have capital construction and working cost is low, save energy, middle water water quality is good, can be used for the advantage of multiple reuse purposes, and simultaneity factor is built in underground, protection face of land view and surrounding environment.
