Description
Technical field
The present invention relates to the water-supply technology field, be specifically related to a kind of device for separating mud and water that is used for low discharge.
Background technology
Depositing reservoir technology is two technical process of flocculation and precipitation to be incorporated in the structures finish, and mainly relies on active sludge to reach the clarification purpose.When taking off steady impurity and contact with the active sludge layer with current, just tackled by slime layer, make mud-water separation.At present, be mechanical accelerating purifying pool at the maximum depositing reservoir of real project using, advantage such as adaptability is strong, stable because mechanical accelerating purifying pool has, effluent quality is good.But in actual moving process, traditional mechanical accelerating purifying pool still exists a lot of problems, mainly contains:
1, backflow active sludge concentration is little, causes the depositing reservoir floor space big.Because the active sludge concentration that refluxes in the standard machinery accelerating purifying pool is less, cause 3-5 that required active sludge capacity of returns is generally flow of inlet water doubly, the area of flocculation zone will be very big like this, and then increase whole depositing reservoir volume, increases cost and operating cost.
2, the problem of space availability ratio deficiency.The current that enter in the mechanical accelerating purifying pool scarcely can look like the design path track: enter first flocculation zone by the triangle distribution channel, finish good flocculation in first flocculation zone; But, directly risen to second flocculation zone by the impeller lifting device by after the water distribution of triangle distribution channel, and so just shortened flocculation time, influence flocculating effect, cause the effluent quality variation, or increase the dosage of medicament.
3, the backflow seam easily stops up.All there is the seam phenomenon of blocking that refluxes in mechanical accelerating purifying pool in a lot of water factories, and simultaneously, in the process of design mechanical accelerating purifying pool, the value of the seam that refluxes also is a more doubt problem.
4, power consumption is big.Because need to promote 3-5 doubly to the body refuse amount of inflow, so need to consume more energy, it is bigger to consume energy.
Therefore, running mechanical accelerating purifying pool in the reality exists shortcomings such as space availability ratio deficiency, backflow body refuse amount are big, floor space big, power consumption is big.
Summary of the invention
The present invention seeks to the above-mentioned not enough a kind of novel muddy water device for effectively separating that proposes at traditional mechanical accelerating purifying pool.
Backflow muddy water device for effectively separating in the pipe/cartridge type body refuse, its be with mechanical flocculation zone, waterpower flocculation zone, depositing technology, concentration technology centralized arrangement in a cylindrical shape pond body.
Described device is that two concentric drums are set in the body of cylindrical shape pond, is separated out mechanical flocculation zone, waterpower flocculation zone, settling zone from inside to outside successively, and the top in three districts is all opened wide, and the bottom is the body refuse enriched chamber.
Described mechanical flocculation zone is communicated with from the top with the waterpower flocculation zone, and the waterpower flocculation zone is communicated with from the lower end with the settling zone, and the water outlet of mechanical flocculation zone enters the waterpower flocculation zone from the top, and the water outlet of waterpower flocculation zone enters the settling zone from the lower end.
Water inlet pipe is inserted in described mechanical flocculation zone bottom, and the middle part is provided with the impeller lifting device, bottom lock, and in the center is provided with active sludge bottom the straight-through body refuse of the return duct/tube enriched chamber; The machinery flocculation zone promotes by the high concentration active sludge of lifting device to bottom, body refuse enriched chamber, the high concentration active sludge is back to mechanical flocculation zone by return duct/tube in the active sludge, the activity and the former water that make full use of body refuse carry out contact flocculation, reinforcement mud-water separation effect, and high concentration active sludge amount can be by rotating speed or convenient, the accurate adjusting of open degree that changes the impeller lifting device.Lifting device can comprise lifting and stir two parts; Lifting can change the body refuse capacity of returns, stirs and carries out the machinery flocculation, and have quantitative coupled relation between capacity of returns and the stirring intensity, can be by changing lifting device mixing speed and open degree adjustment.
Described waterpower flocculation zone is provided with multilayer aperture orifice plate along depth direction, and according to little vortex theory enhanced flocculation, each section energy distribution is reasonable, and the time of staying is short, and flocculating effect is good.
The top outer periphery of described settling zone is equipped with braiding channel, and picks out water pipe by braiding channel.
Middle part, described settling zone is provided with swash plate/pipe, with reinforced deposition, improves capacity utilization, reduces floor space.
Centrifugal pump, pipeline static mixer, flowmeter are housed on the described water inlet pipe, establish chemical feed pipe on the pipeline static mixer; Described body refuse enriched chamber establishes the bottom blow-down pipe and body refuse bucket, and the body refuse bucket is divided into discharge pipeline, is equipped with control valve on every pipe.By electricity (hand) movable valve all is installed on the pipeline, reach automatic medicament feeding system and online flowmeter, nephelometer, can realize automatic control, be convenient to operation and management.
This device is set up active sludge return duct/tube at mechanical flocculation zone bottom centre place, the bottom of straight-through body refuse enriched chamber, cancelled body refuse backflow seam, and change traditional umbrella shape plate of mechanical flocculation zone into straight tubular, increased the waterpower flocculation zone, compare with traditional mechanical accelerating purifying pool, have the following advantages:
1, backflow active sludge concentration is bigger.Machinery flocculation zone bottom centre place has set up active sludge return duct/bottom, the straight-through body refuse of tube enriched chamber, because the active sludge solid content of bottom, body refuse enriched chamber is higher, under the identical condition of required amount of solid, can reduce the capacity of returns of active sludge, be generally handle the water yield 0.5-1.5 doubly, much smaller than the 3-5 of traditional mechanical accelerating purifying pool doubly.Thereby reduced the floor space of flocculation zone and whole device.
2, the active sludge capacity of returns can make things convenient for, control, regulates by the rotating speed or the open degree that change the impeller lifting device accurately.
3, owing to reduced the capacity of returns of active sludge, so can reduce the energy consumption of impeller lifting device, reduced the operating cost of equipment, the energy consumption of specific yield is about about 50% of traditional mechanical accelerating purifying pool.
4, the energy utilization is more thorough and reasonable, and it is more abundant to flocculate.Owing to increased the waterpower flocculation zone in the outside of mechanical flocculation zone, and in the waterpower flocculation zone, added orifice plate, optimize energy distribution, the G value of mechanical flocculation zone is 120S
-1, the G value that waterpower flocculation zone from first to the 3rd flocculation zone adopts successively is 32.8 S
-1, 9.3 S
-1, 4.6 S
-1, the average G value of waterpower flocculation zone is 20 S
-1The total energy input is lower, but because active sludge is recycling, has strengthened the energy reuse indirectly, thereby improves flocculating effect.
5, the backflow of having cancelled in traditional mechanical accelerating purifying pool is stitched, and has avoided the blockage problem of device.
6, space availability ratio height.Tracer test shows that the flow-shape in this equipment carries out according to the flow-shape of design fully, current flow through successively mechanical flocculation zone, waterpower flocculation zone, settling zone, and no space is wasted, and the space availability ratio height almost reaches 100%.
