Description
Technical field
The utility model belongs to technical field of sewage, more particularly to secondary sedimentation tank of sewage treatment work removes algae cleaning device.
Background technology
Second pond is secondary sedimentation tank（secondary settling tank ）Second pond is the weight of activated Sludge System
Part is wanted, it, which is acted on, mainly separates sludge, makes mixed liquor clarification, concentration and returnedactivatedsludge.Its working effect
The effluent quality and returned sludge concentration of activated Sludge System can be directly affected.
Its role is to carry out outside mud-water separation, sludge condensation is also carried out, it is also temporary transient due to the change of water, water quality
Store sludge.Because second pond will carry out sludge condensation, required pool area is more than the pond face only carried out needed for mud-water separation
Product.Sludge has flocculability, belongs to layered precipitation.Precipitation is that have clearly interface between muddy water, and floccule body combines overall common
Sink.
The characteristics of due to second pond and the characteristic of sludge, cause on the outside of the effluent weir of second pond on pool wall to have largely
Sludge and algae, for the existing resourcefulness for removing algae using worker's cleaning, efficiency is low, and when worker is cleaned, exists
Potential safety hazard, lose time to grow so that pond processing is affected.It is although ineffective now with the use of mud scraper.
Utility model content
In order to reach the effective purpose for removing pool wall algae, cleaning performance meets standard, solves worker and cleans in the presence of peace
The problems such as full hidden danger, propose that a kind of secondary sedimentation tank of sewage treatment work removes algae cleaning device.
The technical solution adopted in the utility model is as follows：
Secondary sedimentation tank of sewage treatment work removes algae cleaning device, including second pond and service bridge, it is characterised in that：The service bridge
Central rotating shaft be arranged on second pond center, the service bridge is provided with water pump, and the water pump inlet connects water inlet pipe, described
Water pump water outlet end connects outlet pipe, and the outlet pipe connects water injector, and water injector is placed between mill weir side wall, the water spray
Device is made up of four water pipes, and water pipe is provided with shower nozzle and nozzle.
Further, the outlet pipe is connected by bend pipe.
Further, the shower nozzle is placed in the both ends of top water pipe, the shower nozzle bending, for rinse water weir crest portion.
Further, the nozzle is placed on the water pipe of both sides.
Further, the nozzle uses three-way connection.
Further, water outlet water column pressure is more than 0.8Mpa.
The utility model has the advantages that：
The self-priming water pump of algae-removing device is fixed on service bridge using existing second pond mud scraper rotation, water pump suction pit
Interior supernatant is attenuated by pipeline pressurization and caliber enables water outlet water column pressure to reach 0.8Mpa and then spray to second pond
On the outside of mill weir on pool wall, to reach the purpose for removing pool wall algae.Service bridge rotary speed 1.5m/min, shower nozzle rinse pool wall one
Zhou great Yue 2 hours.General two circles that rinse can rinse pool wall algae well, and flushing frequency can be arbitrarily adjusted according to field condition
It is secondary.About 3 degree or so of once flushing power consumption, 2.5 yuan of expense.
The utility model is simple in construction, can effectively clean algae, realizes automatic cleaning, is combined using shower nozzle and nozzle,
It can simultaneously be cleaned above pool wall on the outside of mill weir and mill weir, under the rotation of service bridge, realize one week and clean, the time
It is short, efficiency high.

Further, the shower nozzle 10 is placed in the both ends of top water pipe, and the shower nozzle 10 is bent, for rinse water weir crest
Portion.
Further, the nozzle 11 is placed on the water pipe of both sides.
Further, the nozzle 11 uses three-way connection.
Further, water outlet water column pressure is more than 0.8Mpa.
Embodiment：
Shown in Fig. 1, the self-priming water pump of algae-removing device is fixed on service bridge using existing second pond mud scraper rotation, water
In the suction pit of pump 4 supernatant by pipeline pressurization and caliber attenuate enable water outlet water column pressure reach 0.8Mpa then spray arrive
On the outside of secondary clarifier effluent weir on pool wall, to reach the purpose for removing pool wall algae.Service bridge rotates speed of travel 1.5m/min, spray
Water installations 7 rinse pool wall about 2 hours one week.General two circles that rinse can rinse pool wall algae well, according to field condition
