Background technology
To in the endogenous pollution control techniques of riverbed silted by mud and sand, Sediment Dredging technology rate of utilization is relatively high.Although, propose to improve technology for environmental dredging that water surrounding is target both at home and abroad and put into practice, but in Dredging Process, produce a large amount of dredging residual water, suspended substance wherein containing high density, nitrogen, phosphorus and organic pollutant etc., the English abbreviation of the suspended substance of high density is SS, and directly discharge will pollute receiving water body.Therefore, while meeting environmental dredging requirement, the qualified discharge of dredging residual water must be met.Correlative study shows, COD, TP, TN and NH3-N concentration of Yu Shuizhong and the remarkable positive correlation of SS concentration.When SS concentration reaches " integrated wastewater discharge standard " (GB8978-2002) secondary standard, COD, TP, TN and NH3-N also all can reach respective standard.Therefore, using SS as the principal pollutant of remaining water and characteristic index, the effluent quality controlling remaining water can be imitated by control SS content.
Existing dredging residual water process all needs to be undertaken by stockyard, is roughly divided into two kinds of modes: one adds flocculation agent in dredging tube, makes its short mix in dredging tube, then reaction precipitation in stockyard.Although this mode does not need separately to build water processing establishment, its chemical feeding quantity is large, and water Chinese medicine residual quantity is higher simultaneously, and being disposed to receiving water body will impact hydrobiological growth and breeding; Another kind then adds flocculation agent to stockyard water outlet, and by removing suspended substance after flocculation sedimentation tank, though which significantly can reduce flocculant dosage, need to build water processing establishment in stockyard, initial cost is large.Obviously, these two kinds of modes all with efficiently, fast ship dredging construction require not to be inconsistent, be badly in need of exploitation dredging residual water online treatment equipment.Meanwhile, correlative study result shows, when gravel particle diameter is lower than 150 μm, pollutent can be polymerized the flco forming macrobead, be easy to precipitation under the effect of flocculation agent, thus accelerates the settling velocity of pollutent, improves scrubbing efficiency.

The problem that the utility model disconnects mutually mainly for residual water treatment and dredging operation, achieves the online treatment of dredging residual water.Different from traditional dredging technique, this equipment can be placed on ship, with suction cutter dredger in working district operation, making Yu Shui dredging simultaneously just energy qualified discharge, greatly improving dredging efficiency.This equipment is boat-carrying online treatment equipment simultaneously, breach tradition dredging facility be all build near stockyard, irremovable limitation, make dredging process realize integration, decrease cost needed for slurry transportation system, at environmental dredging, there is significant advantage economically.
The micro-sand remained in water more than the utility model utilizes realizes micro-sand and increases the weight of flocculating effect.Research shows, the micro-sand being less than 150 μm can aggregate into the oarse-grained flco being easy to precipitate under the effect of polymeric flocculant with pollutent, thus accelerates the settling velocity of pollutent, improves scrubbing efficiency.
The utility model, by the rational modification to settling pit process structure, introduces Coanda effect, improves sand setting effect, achieves continuous sand discharge.Tradition cyclone-type sand precipitating pool can not ensure that away from ingress's flow-shape sand setting effect is not remarkable into effective desanding eddy current flow field.And settling pit gas system channel bend is many, local losses is large, and blower efficiency is low, so remove helical stir equipment, changes into and the process water in post precipitation pond is back to settling pit, apart from water-in remotely jet water outlet, strengthens eddy current flow field.Simultaneously, the flow deflector 13 of eight pieces of arcs is increased in whole eddy flow district, strengthen the gravity settling effect of rotary settling pit 4, and make current along the flowing of flow deflector 13 convex surface, because current and this convex surface exist friction, flow velocity can slow down, according to Bernoulli's theorem, flows decrease causes current to be attracted to flow deflector 13 surface flow, produces Coanda effect, gravel is adsorbed on flow deflector 13 outside surface by this effect, is sink to sludge hopper 11 under gravity.Last sludge hopper 11 is communicated with grit water separator 12, makes gravel discharge settling pit in time, reaches the effect of continuous sand discharge.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
