Brief description
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is this utility model second pond structural representation；
Fig. 2 is this utility model a2o biochemistry pool structural representation.
Specific embodiment
With reference to Fig. 1, Fig. 2, that show the concrete structure of the preferred embodiment of this utility model.Will be detailed below
The construction featuress of each element of this utility model, and during if there are being described to direction (upper and lower, left and right, before and after), be with Fig. 1
Shown structure is with reference to description, but actually used direction of the present utility model is not limited thereto.
The modal technological process of traditional life Sewage Plant is: coarse rack, elevator pump, fine fack setting pot, a20 are biochemical
Pond, second pond, ultraviolet disinfection, water outlet, effluent quality commonly reaches " urban wastewater treatment firm pollutant emission standard "
(gb18918-2002) one-level b, one-level b water outlet leading indicator ammonia nitrogen 8mg/l, cod60mg/l, total phosphorus 1mg/l.Using this practicality
New mbr technique be applied to built Sewage Plant carry mark extending capacity reformation, make full use of original cell body, by changing to original cell body
Make and reach the purpose carrying mark extending capacity reformation, on the premise of not increasing total floor space, only newly-built preprocessing part (coarse rack,
Elevator pump, fine fack, setting pot) cell body, this part accounts for the Sewage Plant gross area 2%, the Sewage Plant process water yield is doubled, goes out
Water water quality reaches terrestrial reference four class water quality standard in addition to total nitrogen, earth's surface four class water water outlet leading indicator ammonia nitrogen 1.5mg/l, cod30mg/l,
Total phosphorus 0.3mg/l.Below Sewage Plant actual water outlet ammonia nitrogen 0.5mg/l, below cod15mg/l.
Specifically, this utility model provides a kind of sewage treatment plant and carries mark extending capacity reformation treatment tank, the master of transformation
Body is a20 biochemistry pool 1 and second pond 2, and a2o biochemistry pool 1 and second pond 2 are along water inlet to the setting of water outlet direction, traditional life sewage
Treatment plant's second pond 2 floor space is big, setting partition wall in described second pond 2, and second pond 2 is divided into membrane cisterna aerobic zone by partition wall
21st, mbr membrane cisterna 22 and sludge reflux area 23, membrane cisterna aerobic zone 21, the both sides of the 23 points of row mbr membrane cisternas 22 in sludge reflux area, film
The space of pond aerobic zone 21 is more than the space in sludge reflux area 23, setting mbr membrane component, sludge reflux in described mbr membrane cisterna 22
Area 23 is connected with a2o biochemistry pool 1 by being provided with the pipeline of sludge pump, and mud is back to a20 biochemistry pool 1 in a large number, improves biochemistry pool
Sludge concentration, improves and processes load, thus reducing the time of staying, processes the double purpose of the water yield.Meanwhile, by second pond
The newly-built corresponding equipment room in side 2, one layer of equipment room mainly has mbr water production system, backwashing system, purging wind system, evacuation
System, medicine system etc., the equipment such as aerator, air compressor machine is installed on one layer of equipment room, and two layers of equipment room is used for distribution, automatic control system
System.After ultraviolet disinfection canal, effluent quality reaches terrestrial reference four class water quality standard in addition to total nitrogen for membranous system water outlet.
The Modification of Secondary Settling Tank of original system is three parts: 1. membrane cisterna aerobic zone 21 by this utility model, increases aerobic unit and stops
Stay the time, 2. sludge reflux area 23, the mud after mbr filtering and concentrating is pumped into a2o biochemistry pool, 3.mbr membrane cisterna 22, by mbr film
Element is positioned in membrane cisterna, by the high-precision filtration of mbr film, obtains the water outlet of high-quality, goes out aqueous suspension and almost detects not
Arrive, thus reaching the purpose of lifting water quality.
12 hours traditional wastewater treatment plant a20 biochemistry pool time of staying, sludge concentration 3500mg/l about, by mbr skill
Art, sludge concentration can be promoted to more than 7000mg/l, and the a2o biochemistry pool time of staying can foreshorten to 6 hours, utilizes from realization
Original cell body reaches the double purpose of aquifer yield.The function of only original cell body need to being carried out again divides, and increases parting wall, real
Existing original function.That is, setting drain wall in a2o biochemistry pool 1, a2o biochemistry pool 1 is divided into along water side of intaking drain wall
To the anaerobic pond 11, anoxic pond and the Aerobic Pond that are sequentially distributed.One jiao of described a2o biochemistry pool 1 and set in the upstream of anaerobic pond 11
Have and select area 12 into water.It is provided with the first training wall 13, anaerobic pond 11 is formed by the first training wall 13 in the middle part of described anaerobic pond 11
Annular walks aquaporin.Described anoxic pond includes 14, the two grades of anoxias of one-level anoxic pond being sequentially distributed along the water outlet direction that intakes
Pond 15, three-level anoxic pond 16 and level Four anoxic pond 17, are provided with the second training wall 18, one-level anoxia in the middle part of described one-level anoxic pond 14
Aquaporin is walked by what the second training wall 18 formed annular in pond 14, two grades of anoxic pond 15, three-level anoxic pond 16 and level Four anoxic pond
The 17 drain walls passing through each other form the aquaporin of walking of s shape, and anoxic pond arranges level Four, increases the anoxia time of staying, reduces
Total nitrogen difficulty up to standard.Described Aerobic Pond includes 19, the two grades of Aerobic Ponds of one-level Aerobic Pond being sequentially distributed along the water outlet direction that intakes
110th, three-level Aerobic Pond 111 and level Four Aerobic Pond 112,19, two grades of Aerobic Ponds 110 of one-level Aerobic Pond, three-level Aerobic Pond 111 and four
Level Aerobic Pond 112 walks aquaporin by drain wall formation s shape each other.
By upgrade expanding transformation is carried out to traditional wastewater factory using technique scheme, before not increasing floor space newly
Put, make full use of original cell body, it is possible to achieve aquifer yield doubles, effluent quality is by " urban wastewater treatment firm pollutant
Discharge standard " (gb18918-2002) one-level b, directly it is promoted to earth's surface four class water quality standard (except total nitrogen), with using traditional work
The technique of skill+advanced treating is compared, and saves floor space more than 50%, and cost of investment saves more than 40%, solves city built
In Sewage Plant upgrade expanding transformation process because of floor space not, need newly-increased soil, removing of bringing is difficult, difficult the asking of expropriation of land
Topic.
Certainly, the invention is not limited to above-mentioned embodiment, and those of ordinary skill in the art are without prejudice to this
Equivalent variations or replacement also can be made, these equivalent modifications or replacement are all contained in the application on the premise of utility model spirit
In claim limited range.
