Description

A kind of efficient high-turbidity sewage cleaner

The utility model belongs to the environmental protection equipment effluent treatment plant.

In the age of current develop rapidly, environmental pollution has become the significant obstacle of human survival and development, especially rationally the quoting and redeveloping of water resources, and the effect that sewage purification device played has obtained people's common attention and care.But it is not high that existing sewage purification device all exists influent turbidity to some extent, water production rate is little, and efficient is low, a series of problems such as operational management and maintenance trouble, its technical process, aspects such as quality of purifying waste water and comprehensive technical performance also remain further to be improved and improve.

The purpose of this utility model be to provide a kind of with mixing, reaction, suspension clarification, precipitation, filtration, clear water compiles and mud simmer down to one, has the effluent treatment plant that can handle high turbidity.Has the purification efficiency height, the ideal effect that technical process is short.

The utility model sewage purification device is according to chemical coagulation, filtering under pressure and hydraulic principle design.This device is made up of institutes such as retort (1), main cylinder (15), spoil disposal bucket (17) and pipe arrangements.The principle of work of this device is: the fs, characteristics according to coagulation process, requirement sewage and coagulating agent uniform mixing, is arranged on the sump pump suction inlet place that draw sewage with dosing mouth with utmost dispatch, utilizes the water pump impeller of high speed rotating can play good stirring action.Sewage at first enters retort (1) and carry out contact reacts with porcelain ball layer (2) in reaction zone (3), tangentially enters in the inner barrel (20) through water folding pipe (4) then, and the sewage that is in turbulent state begins rotation and plays stirring action.

Subordinate phase suspension zone (6) is the zone that alumen ustum forms and grows up gradually, and structure design herein is the taper inner barrel (18) that flow velocity slows down gradually, requires to slow down stirring velocity gradually, in order to avoid the bulk alumen ustum is smashed.

Phase III is settling section (7), and tank body sectional area maximum makes the flow velocity that makes progress the slowest herein, is beneficial to alumen ustum in this sedimentation.

The tetravalence section is filtrating area (9), adopts the poly-third vinyl plastics pearl as filtrate (13) water after the clarification further to be purified again through media filtration.In order to increase the relative velocity of flow of filtering layer, make and form the pressure reduction increase that bypass refluxes, improve the separating power that mud enters mud concentration compartments (5) simultaneously main cylinder (15) top filtrating area (9) is located to be made as back taper cylindrical shell (14), the sectional area that makes filtrating area (9) purifies the big fireballing effect of the water yield gradually less than the sectional area of main cylinder (15) so that reach.Constantly the current that rise enter catchment area (12) through filter head plate (10), directly send clear water to go into water tower or supply user by rising pipe (11) then.

The utility model also is provided with mud concentration compartments (5) and forces effluent recycling pipe (8), and the settled mud in cohesion back is concentrated to the tank body center, through spoil disposal bucket (17), enters mud concentration compartments (5) sedimentation by radiator tube (19).In order to improve amount and the speed that mud enters spoil disposal bucket (17), the top of spoil disposal bucket (17) is made as spoil disposal bucket cone (16) greater than bung, strengthened spoil disposal bucket area suitable for reading like this, slowed down the speed that suspension zone (6) mud rises.According to the filtered water mechanics principle, filtrating area (9) adopts the poly-third vinylic foam pearl to constitute filter bed and flow rate of water flow, under this flow rate regime, force below effluent recycling pipe (8) the level part, filtrate head loss calculated value is greater than 6.6 meter water columns, and force the drag losses calculated value in the effluent recycling pipe (8) only is 0.5 meter water column, by the formed pressure reduction of both pressure differences, having formed jar intravital bypass flows, be that alumen ustum constantly enters mud concentration compartments (5), the more clear water in top, concentration compartments (5) is pressed into automatically forces effluent recycling pipe (8), enters in the filtrating area (9), becomes clear water through the filtration of first half filtrating area and enters catchment area (12).And settled mud is concentrated in the concentration compartments, has prolonged sludge discharging period, has promptly reduced the water ratio of mud, has increased total water production rate again relatively.When reaching certain sludge concentration and after the work period, opening annular shore pipe outlet (22), discharge the mud in the annular shore pipe (21).

The back flushing of filtrate (13) is generally shut down after 8 hours when work, opens recoil pump, and recoil water is entered by rising pipe (11), opens the sewage after recoil blow-off pipe (23) is discharged flushing after flushing finishes.

The retort design is outside main cylinder (15) in addition, and the knot that can increase water and medicament like this touches the time, and also helps maintaining.The primary features of this device is: current tangentially enter formation " point unit vortex " with certain angle and flow, and form, grow up the stage at alumen ustum, spiral motion, the chance that has increased collision between particulate, absorption greatly and condensed makes coagulation more fill part.Main is that after entering settling section, speed of rotation reduces, promptly " circulation strength " is controlled at a threshold value when following, the centrifugal force that alumen ustum obtained is less, according to " point unit vortex " flow principles, and the tank body center of radius minimum, the speed maximum, pressure is then less, and radially under the inside and outside differential pressure effect, alumen ustum is concentrated to the tank body center rapidly at tank body, and enter the spoil disposal bucket, thereby improved the separating effect of alumen ustum (mud) significantly with water.

The utility model is a kind of refining plant of high-turbidity sewage efficiently, and its floor space is little, operates tube just, and working cost is low, and comprehensive technical performance all can reach ideal effect.Can realize the process water closed cycle, and recyclable precious raw material.Especially be fit to boiler granite duster, coal mine sewage, casting, pottery, papermaking, metallurgy, chemical industry every profession and trade, and the application of waste water such as water mill marble, wet dedusting.To the control environmental pollution, water saving all has remarkable social benefit and economic benefit.
