Description
Technical field
The invention belongs to technical field of sewage, in particular to a kind of train is filled with vacuum sewage biodegrade dirt box
It sets and sewage water treatment method.
Background technique
Currently, the closet sewage of high-speed rail and motor train unit train is collected under vehicle by vacuum feces collecting system in dirt box.
Since dirt box only collects not waste discharge in train operation, passenger-flow rush hours often will appear dirt box spill-over, lead to vacuum
The case where closet pause uses, makes troubles to passenger.Waste water in dirt box must be taken out by surface personnel daily
Fortune, waste water are unified to carry out processing discharge by sewage treatment plant into city planting ductwork after septic tank pre-processes.It not only expends big
Manpower and material resources are measured, and working environment is poor, adversely affects to the health care belt of worker.
Existing online sewage-treatment plant is that theoretically may be implemented mostly, and actually train wastewater pollutants concentration
Height, COD, ammonia nitrogen, suspension content are high, although B/C ratio, in 0.5 or so (good biodegradability), C:N:P nutrition is lost than serious
The strain and filler that weighing apparatus, conventional anaerobism and aerobic treatment use are suppressed under such mal-condition, it is difficult to be carried out
Normal vital movement, or even can not survive, it is fairly limited to the treating capacity and processing capacity of sewage, GB18918- is not achieved
Secondary standard in 2002 " urban wastewater treatment firm pollutant emission standards ".And train dirt box it is daily sewage quantity it is reachable
600L, the railway network is intensively flourishing at home, and in the environment of core city, even if carrying out enough sterilizings to water outlet
Processing, also can not negate that it accumulates over a long period to ecological pollutions such as periphery people, big gas and waters.
Summary of the invention
The present invention solves the technical problem of provide a kind of not only certifiable effluent quality and meet in line standard, but also can
The train vacuum sewage biodegrade dirt case apparatus of sewage treatment capacity is greatly improved, while a kind of dirt of device being provided
Method for treating water.
To achieve the above object, the technical scheme is that
A kind of train vacuum sewage biodegrade dirt case apparatus, including dirt box and control system, the dirt box
Interior to have interconnected Biological Pretreatment room and advanced oxidation room, the Biological Pretreatment room is for tentatively dropping dirt
Solution, by pollutant norm controlling within the scope of primary criteria, the advanced oxidation room is used for by dirty in pretreated water
Contaminate object carry out exhaustive oxidation decomposition, by pollutant norm controlling within the scope of discharge standard direct emission rail.
Further, there is the biological culture room and biological room being sequentially communicated in the Biological Pretreatment room；The life
Object culturing room separates for solid and liquid, and solids is trapped in biological culture room, and liquid flows into biological room, in institute
Stating biological culture indoor location has upper layer and lower layer strainer, and filler, the filler are filled between lower screen and upper screen
On be attached with anaerobism high-efficiency strain；There is anoxic zone, aerobic zone and the ultrafiltration membrane group area being sequentially communicated in the biological room,
Biologic packing material and aeration tube are installed in anoxic zone and aerobic zone, treated, and water flows into ultrafiltration membrane group area；Described
Ultrafiltration membrane group indoor location has MBR filter membrane component and the pipeline that catchments, and treated, and clear water enters the advanced oxidation room.
Further, being mounted on the indoor filler of the biological culture is ceramics filling, and the ceramics filling is pressed from bottom to top
Partial size difference is divided into multilayer from large to small.
Further, the biologic packing material of the biological indoor location is polyurethane biologic packing material, adds high-efficiency strain training
Support biomembrane.
Further, the high-efficiency strain is made of nitrifier, denitrifying bacterium and the bacillus tamed.
Further, ultrafiltration membrane group area is provided with high-order liquid-level switch, low level liquid-level switch and warning liquid-level switch,
The liquid level in ultrafiltration membrane group area attain to a high place liquid-level switch when control draining, reach low level liquid-level switch time control stop only drain, reach
To warning liquid-level switch alarm prompt.
Further, have a multiple stack electrolyser and power module in the advanced oxidation indoor location, the electrolysis unit by
The titanium-matrix electrode plate that muti-piece is alternately arranged is constituted, and every group of electrolysis unit is connect in the form of concatenated with power module.
Further, it is provided with the high pressure washing valve for rinsing dirt box, flushing drain valve on the dirt box and is used for
The dosing purge valve of dosing cleaning dirt box.
Another technical solution of the invention is:
A kind of train sewage water treatment method of vacuum sewage biodegrade dirt case apparatus, specifically comprises the following steps:
A, sewage and dirt flow into biological culture room first, and solids is trapped the bottom in biological culture room, sewage according to
It is secondary to enter biological room after filter screen and filler filtering, anaerobism high-efficiency strain is cultivated in the filler of biological culture room, is made
Sewage is sufficiently reacted with anaerobic bacteria, completes the process of hydrolysis acidification；
B, sewage successively passes through the indoor anoxic zone of biological, aerobic zone and ultrafiltration membrane group area, pollutant and successively passes through
The biodegrade processing of anaerobic and aerobic microorganism, realizes mud-water separation using ultrafiltration membrane group area, filtered water is pumped
To in advanced oxidizing chamber, the pretreated water of biodegrade meets the primary criteria for entering advanced oxidation step；
C, in advanced oxidation room, the oxidizing species generated using electrolysis unit, exhaustive oxidation decomposes residual in water
Remaining pollutant, treated, and water reaches discharge standard；
D, through treated for advanced oxidation room, water is directly discharged to outside vehicle on rail.
Further, biological room is controlled when the liquid level of biological room attains to a high place liquid level to drain to advanced oxidation
Room controls biological room when the liquid level of biological room is reduced to low level liquid level and stops draining；When the liquid of biological room
Position reaches warning liquid level alarm prompt.
To sum up content, a kind of train vacuum sewage biodegrade dirt case apparatus and sewage treatment side of the present invention
Method realizes the online processing function of sewage and dirt, passes through each works such as biodegrade pretreatment and advanced oxidation advanced treating
The rationalization of skill step, it is ensured that under train operation state, water can be handled daily and reach 600L, solid matter is trapped storage
It deposits, treated, and water fully meets secondary standard in GB18918-2002 " urban wastewater treatment firm pollutant emission standard ", water
Rail can be emitted into vehicle, solids is by website periodic cleaning.The present invention is not only interior in a limited space have been played to greatest extent
Processing capacity, it is ensured that water treatment efficiency and quality, it is low to solve conventional treatment mode treating capacity, the defect of poor processing effect,
And the website clean-up operation period is extended, original Ground Processing System is saved, mitigates the load of back-end processing factory, while also not
Ecological pollution can be caused to ambient enviroment and geology, the requirement of train on-line operation can be fully met, realized really ON TRAINS
It is applied.
The present invention can be used for the train of high-speed rail motor-car, common speed, can be used for vacuum feces collecting system or gravity type system is received
The sewage treatment of collection.
