Description
Technical field
The present invention relates to a kind of sewerage integrated treatment unit, be specially adapted to train sealed-type toilet urinal fecal sewage integrated treater.
Background technology
In order to protect railway ecotope along the line; world's pilosity reaches country the defecate collection device was installed ON TRAINS in a large number since the seventies in 20th century; in order to collect passenger's movement, avoid arbitrarily draining along railway, also set up perfect ight soil simultaneously on ground and received and treatment facility.Developed country is very perfect because of municipal sewage pipe network and treatment system, population is less relatively, therefore generally all be after simple process, to drain into municipal sewage pipe network to collecting ight soil, discharge after transporting to municipal sewage plant and municipal effluent combination treatment, that defecate collection device sewage is handled separately and directly discharged is less.Though there are indivedual countries to adopt methods such as membrane bioreactor, charcoal absorption, High Temperature High Pressure wet oxidation, electrofloatation to handle defecate collection device waste water, processing costs costliness, complex management as Japan, Germany, Korea S etc.
The urinal fecal sewage water quality BOD of analysis-by-synthesis China passenger train sealed-type toilet
5Concentration is generally 2000～4500mg/L, COD
CrBe between 5000～8000mg/L, ammonia nitrogen is 800～1300mg/L, and ss suspended solid is 650～1500mg/L.To this water quality, at present, China mainly takes to transfer to the outward transport of local environmental sanitation department and handles.But because the outward transport expense is higher, the passenger station that has builds sewage works defecate collection device sewage is carried out special disposal in the whole institute of visitor, and a kind of method is to enter municipal sewage system to converge to the municipal sewage plant after simple precipitation is handled; Another kind is that fecal sewage can not import the municipal sewage plant through simple process, needs individual curing and qualified discharge.Present running condition from individual curing, its complex treatment process, operation conditions is relatively poor, and the water outlet ammonia nitrogen concentration is higher, can not realize qualified discharge.
Make a general survey of the present Research that fecal sewage is handled, urinal fecal sewage is directly handled does not also have the economically feasible method at present.High speed development along with Chinese Railway, starting in a large number of EMUs, a large amount of motor-car urinal fecal sewages will be produced, water quality and quantity altered a great deal with compare in the past, press at current Chinese passenger train urinal fecal sewage water quality characteristics, at Chinese fecal sewage emission request, development new technologies new installation.
