Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of buried phosphate fertilizer reclamation set and sewage disposal side on the spot
Method.
Background technology
In daily life, the sanitary sewages such as cheap Powdered Detergent Containing Phosphate pass through due to a lack of perfect sewage disposal system
The approach such as diafiltration or directly unordered discharge enter river, lake etc., and the discharge of a large amount of phosphorus causes water pollution and eutrophication
The problems such as.Therefore, phosphorous domestic sewage treatment becomes a research hotspot urgently to be resolved hurrily.
It is mainly focused on the removal of phosphor in sewage both at home and abroad at present, and the recycling of phosphorus is not affected by abundant attention always.
For the removal of phosphorus, bioprocess technology, ecological process and biological-ecological group technology are mainly used in engineering at present, specifically
Method includes A/O, biofilter, septic tank, stabilization pond, artificial swamp and soil filtration technology etc..From the point of view of operational effect,
Each technique all there are it is more or less the problem of.For example, stabilization pond treatment technology is to utilize microbial degradation, sedimentation, conversion, retention
The effects that remove pollutant, however total phosphorus content is high in water outlet, water outlet situation not up to standard occurs, and with take up a large area,

Power, but its dephosphorization efficiency is relatively low.Using more ripe anaerobic-aerobic biological treatment technique-reinforced phosphor-removing technique fortune
In row, although phosphorus ligands efficiency is higher, industrial wastewater is unavoidably mixed into city domestic sewage, causes heavy metal and other
Poisonous and harmful substance is coexisted in phosphorus in excess sludge, it is difficult to recycle, solid is used as after final concentrated, digestion, dehydration
Waste is landfilled processing.In this way, phosphorus is not only wasted as a kind of scarce resource, if also to Groundwater after permeating the ground
Matter causes profound influence, and being discharged into rivers and lakes after the molten leaching of rainwater is also easy to cause body eutrophication.In fact, new rural village society
There are dramatically different, which is not polluted by industrial enterprise for area's sanitary sewage and city domestic sewage, without heavy metal and other
Poisonous and harmful substance, organic constituents only contain COD（COD）, nitrogen, phosphorus etc..Therefore, the phosphorus in domestic sewage in rural areas
Recycle the interference from undesirable element.In this way, sanitary sewage excess sludge after biological treatment passes through and stalk, green manure, weeds
Vegetable matters is waited to become composting fertilizer after stack retting.Compared with municipal sewage phosphorus recycles, new rural planning is nearer from farmland, raw
The phosphorus recycling of sewage living not only has more advantage in feasibility, but also can realize and apply on the spot or closely have and save fortune
The advantages such as take, be easy to operate.
