Description
Technical field
The invention belongs to environmental wastewater and administer the field, concrete a kind of dispersed domestic sewage in rural areas by using treatment system and the sewage treatment process thereof of relating to.
Background technology
Known; Taihu Lake basin belongs to the highly developed area of China's rural economy; People in the countryside are intensive, and the sewage quantity discharged is big, in its contribution rate to the Taihu Lake pollution; Nitrogen, phosphorus account for respectively about 35% and 60%, and the domestic sewage in rural areas by using that has a large capacity and a wide range enters water body has become the major reason that causes body eutrophication.Therefore, research and development application construction investment province, the domestic sewage in rural areas by using treatment technology that working cost is low, scrubbing usefulness is high have important practical significance to promoting Chinese society doctrine new countryside construction.
The structure of country sewage treatment system should be established the theory of " suit measures to local conditions, biological and ecological, comprehensive utilization, the system integration "; The principle that, scrubbing usefulness low in line with processing cost is high, realize recycling; Adopt biological and ecologic facies bonded processing mode, form the treatment technology that meets domestic sewage in rural areas by using water quality, the water yield and discharging and collection characteristic.
Anaerobic baffled reactor (ABR) is as a kind of high-efficiency sewage anaerobic biological treatment technology; It is high to handle load; Capacity of resisting impact load is strong; ABR has been carried out certain research both at home and abroad; The content of research mainly concentrate on different factors to the influence of the treatment efficiency of ABR, with the comparison of other anaerobic treatment process, reactor drum in Changing Pattern, the usefulness of handling high, medium and low concentration waste water and the aspect such as stable of mikrobe, mainly be the treatment of high concentration trade effluent, the less domestic sewage treatment that is applied to.
Artificial swamp is to use the rational environmental technology in a kind of economy of domestic sewage in rural areas by using processing; Its not only can suit measures to local conditions to utilize existing place and topographical condition; Realize processing through absorbing of plant to waste water with mikrobe and physicochemical acting in conjunction; Being beneficial to simultaneously handling the recycling of back water outlet, is the treatment technology comparatively widely of research at present.But this art breading load is low, takes up an area of extensively, is difficult to directly accept without pretreated former water, and the due pre-treatment of waste water process that requires to get into this treatment process is to reduce SS and the COD in the water inlet
Cr
