As shown in Figure 1, 2, traditional tube settler comprises inlet channel 1, tube settling district 2, brace summer 3, mud drainage slot 4 and perforated sludge discharge pipe 5.6 is invalid discharge area.The sludge drainage system of tradition inclined tube (swash plate) sedimentation basin generally adopts perforated sludge discharge pipe 5 spoil disposals or siphon suction dredge spoil disposal.Owing to adopt the perforated sludge discharge pipe spoil disposal usually can produce the problem that spoil disposal is inhomogeneous, the local deposition of inclined tube affects effluent quality, therefore, generally adopt siphon suction dredge as the soil discharging facility of tube settler in the design at present.The sludge discharge effects of this system is good, but has following limitation.
1) be subjected to the restriction of siphon suction dredge device fabrication requirement, the suction dredge span is generally less than 17m, so pond body width is also corresponding limited, and pond body flexible arrangement is under some influence.
2) owing to the equipment installation requirement of suction dredge, twice beam fastening all need be arranged in both sides in the body of pond, will reduce thus the effective area of sedimentation basin.With 7.5 ten thousand m
3The tube settler of/d is example, adopts the siphon suction dredge spoil disposal, and its effective inclined tube area will reduce about 15%.
3) because siphon suction dredge does not possess the mud concentrating function, and generally speaking, the spoil disposal water concentration is lower than 1%, sludge from sedimentation tank water must be introduced into concentration basin concentrated after, the dehydration machine room of being allowed for access is processed.
To sum up, in traditional inclined tube (swash plate) sedimentation basin technique, exist the pond body to arrange that size-constrained, effective inclined tube area reduces and the relatively low problem of spoil disposal water concentration.
The utility model content
The purpose of this utility model is to provide a kind of inclined tube or inclined-plate clarifying basin with mud concentrating function, is suitable for limited newly-built (enlarging) Waterworks of construction land.Solved traditional tube settler water inlet width dimensions limited, exist invalid discharge area, spoil disposal not thoroughly and the relatively low problem of spoil disposal water concentration.
To achieve these goals, the technical solution of the utility model is: a kind of inclined tube or inclined-plate clarifying basin with mud concentrating function, comprise the pond body, it is characterized in that on body top, pond inclined tube or swash plate being set, inclined tube or swash plate top arrange water leg, in sedimentation basin one side mud-removing bucket is set, body bottom in pond arranges first and continues push type concentrated soil discharging facility under water.Also be provided with the collection mud pit in the described mud-removing bucket, the mud-removing bucket bottom arranges second and continues push type concentrated soil discharging facility under water.In the pond external body mud counterbalance cell is set, the collection mud pit is connected to the mud counterbalance cell by discharge pipeline.
Supernatant is delivered to the filter tank after collecting by the stainless steel water leg, deposition is then at the bottom of inclined tube or swash plate fall into the pond automatically, continue push type by first and concentrate the concentrated pusher of soil discharging facility under water to bucket, concentrate soil discharging facility under water by the second lasting push type that arranges in the bucket again and be pushed into again the collection mud pit, after deposition reaches some within collecting the mud pit, directly drain into the mud counterbalance cell by discharge pipeline, send into again dehydration machine room and process.The utility model continues push type concentrated soil discharging facility under water by arranging at the bottom of the pond, it is more flexible that pond body size is arranged, avoided simultaneously traditional tube settler to have the problem of invalid discharge area.In addition, this pond sediment brings up to 2% ~ 3%,, mud extraction can satisfy the centrifugal dewatering of sludge machine or plate and frame filter press advances the mud requirement, thereby has saved spoil disposal water regulating reservoir and sludge concentration tank in traditional spoil disposal water treatment technology.In addition, concentrated soil discharging facility under water is set separately in the bucket, makes deposition concentrate on the discharge pipeline entrance, spoil disposal is thorough, makes at the bottom of the whole pond in long-time running without local deposition block.The utlity model has that construction investment is economized, floor space is little, management advantage relatively easily, realized the optimum organization of water treatment plant's treatment process.
