Description

Lime adding device of pretreatment system in sewage treatment system

Technical Field

The utility model particularly relates to a pretreatment systems lime dosing unit among sewage treatment system belongs to sewage treatment device technical field.

Background

For sewage treatment systems, lime addition is a commonly used mode in the pretreatment process. In most sewage treatment plants, the existing process is to store lime milk in a lime storage tank and to add chemicals (lime) to a plurality of sewage pools simultaneously. The setting adds the medicine pump with the effluent water sump equivalent, and every adds the medicine pump and adds the medicine for an effluent water sump, and a plurality of medicine pumps that add of this kind of mode are worked simultaneously, and the pipeline is complicated and big to lime breast disturbance, cause lime breast pipeline to block up easily to the clearance difficulty.

The Chinese utility model patent, CN202729871U, discloses a device for solving the problem of lime dosing pipe pollution and blockage in water treatment, and the method has a complex structure and can not fundamentally solve the problem.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model discloses throw with throwing problem that pipeline easily blockked up to sewage pretreatment lime among the prior art, design a pretreatment system lime and throw feeder apparatus among sewage treatment system.

The novel specific scheme is as follows:

the utility model provides a pretreatment systems lime dosing unit among sewage treatment system, includes lime storage tank, dosing pump, distribution ditch, effluent water sump quantity is more than 6, and dosing pump quantity is more than two, and two in the whole dosing pumps are connected between lime storage tank and distribution ditch, and distribution ditch intercommunication effluent water sump.

Further, the sewage tank comprises a sedimentation tank, a front mixing tank, a mixing tank and a flocculation tank.

Further, the number of the dosing pumps is 6, and two dosing pumps are connected between the lime storage tank and the distribution ditch.

Further, the number of the sewage pools is 6.

Furthermore, the 6 dosing pumps are also directly communicated with the 6 sewage pools respectively.

Further, the dosing pump is a horizontal centrifugal pump.

This neotype beneficial effect lies in: the utility model provides a pretreatment systems lime dosing unit in sewage treatment system sets up the distribution ditch through throwing the change of adding the point, only needs two dosing pumps just can satisfy the lime of a plurality of effluent water ponds and throw the needs, has realized improving high-density effluent water quality of pond, has avoided the factor of puzzlement production such as easy jam of dosing pipeline, clearance difficulty, has practiced thrift electric energy and spare part consumption.

Detailed Description

The following description of the embodiments of the present invention is provided with reference to the accompanying drawings:

as shown in fig. 1, the lime adding apparatus of the pretreatment system in the sewage treatment system provided in this embodiment is used to solve the problem of lime pipeline blockage in sewage pretreatment.

As shown in fig. 1, the lime adding apparatus of the pretreatment system provided by this embodiment includes a lime storage tank 1, a distribution ditch 2, and 6 sedimentation tanks, which are respectively a # 1 sedimentation tank 31, a # 2 sedimentation tank 32, a # 3 sedimentation tank 33, a # 4 sedimentation tank 34, a # 5 sedimentation tank 35, and a # 6 sedimentation tank 36, and each sedimentation tank includes a front mixing tank 6, a mixing tank 5, and a flocculation tank 7.

In this embodiment, the dosing pump is a centrifugal horizontal pump, the dosing pumps for dosing are a 3# dosing pump 43 and a 4# dosing pump 44, one end of each of the 3# dosing pump 43 and the 4# dosing pump 44 is communicated with the lime storage tank 1, the other end of each of the 3# dosing pump 43 and the 4# dosing pump 44 is connected with the distribution channel 2, the distribution channel 2 is communicated with the 6 sedimentation tanks, and lime is pumped out of the lime storage tank 1 by the dosing pumps and is added into the 6 sedimentation tanks through the distribution channel 2. Two dosing pumps meet the lime feeding requirements of 6 sedimentation tanks.

As a preferred embodiment, the device is improved on the basis of the original device, the original device has 6 dosing pumps in total, and the 1# dosing pump 41, the 2# dosing pump 42, the 5# dosing pump 45 and the 6# dosing pump 46 are arranged in addition to the two dosing pumps, and a pipeline directly communicated with the sedimentation tank of the 6 dosing pumps of the original device is reserved and is not used as a standby dosing scheme under normal conditions.

Through implementing the technical scheme of this embodiment, the technical effect that produces is as follows:

1. the quality of the outlet water of the high-density water tank is greatly improved.

2. Can save the lime adding amount and save the medicament.

3. Spare part consumption is saved: the replacement period of the stator of the lime dosing pump is 3 months, and the spare part cost of 4 dosing pumps is saved by 4 x 4000 64000 yuan all the year according to the current high-density running amount, so that the power consumption of 4 pumps is saved. The running frequency of each pump is 50HZ for one year, so that the power consumption can be saved by 4KW 4h 24h 365 kWh 140160KWh, and the power consumption is calculated according to the following power consumption per degree: the calculation of 0.38 yuan/KWh can save the electricity charge: 140160KWh 0.38 yuan/KWh 53261 yuan.
