Background technology
At present along with the improvement of people's life, developing rapidly of industry, the pollution of following environment is also more and more serious.And sewage disposal is widely used in building, agricultural, the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, also come into the daily life of common people more and more.Owing to containing a large amount of heavy metal elements in waste water, can not reach emission standard when discharging, therefore we need cleaning and the process of carrying out a heavy metal element before discharging.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of modified meerschaum is provided to remove the refining plant of heavy metal in polluted water, its structure is simple, reasonable in design, effectively can remove solid particulates a large amount of in heavy metal contaminants and sewage in sewage.
The technical scheme that the utility model adopts is: a kind of modified meerschaum removes the refining plant of heavy metal in polluted water, comprise coagulation tank and second-stage treatment tank, described coagulation tank top is provided with sealing cover, described coagulation tank top is provided with water inlet pipe, side, coagulation tank top is provided with exhaust-valve, opposite side is provided with rising pipe, piston is provided with in described coagulation tank, piston base is connected with the piston rod stretched out outside coagulation tank, one end that described piston rod stretches out coagulation tank is connected to driving cylinder, also aeration tube is provided with in described coagulation tank, described aeration tube is between exhaust-valve and piston and near aeration tube place, several aeration head is provided with bottom described aeration tube, water outlet pipe part in described coagulation tank is provided with particle filtration net, one end of described rising pipe is positioned at coagulation tank, the other end is communicated with second-stage treatment tank, whipping appts is provided with in described second-stage treatment tank, described whipping appts is circumscribed with motor, modified meerschaum medium is filled with in described second-stage treatment tank, second-stage treatment pot bottom is provided with water shoot.
As preferably, the downward-sloping setting of described aeration head, and and in 45 degree of angles between aeration tube.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the immobilized particles in sewage can be removed fast and effectively, and the heavy metal contaminants can removed in sewage, adopt modified meerschaum medium simultaneously, sepiolite wide material sources, cheap, and can use be regenerated, greatly save decontamination cost and a large amount of natural resourcess, there is higher economic benefit.

Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the utility model comprises coagulation tank 1 and second-stage treatment tank 2, described coagulation tank 1 top is provided with sealing cover 3, described coagulation tank 1 top is provided with water inlet pipe 4, side, coagulation tank 1 top is provided with exhaust-valve 5, opposite side is provided with rising pipe 6, piston 7 is provided with in described coagulation tank 1, the piston rod 8 stretched out outside coagulation tank 1 is connected with bottom piston 7, one end that described piston rod 8 stretches out coagulation tank 1 is connected to and drives cylinder 9, aeration tube 10 is also provided with in described coagulation tank 1, described aeration tube 10 is between exhaust-valve 5 and piston 7 and near aeration tube 10 place, several aeration head 11 is provided with bottom described aeration tube 10, rising pipe 6 place in described coagulation tank 1 is provided with particle filtration net 12, one end of described rising pipe 6 is positioned at coagulation tank 1, the other end is communicated with second-stage treatment tank 2, whipping appts 13 is provided with in described second-stage treatment tank 2, described whipping appts 13 is circumscribed with motor 14, modified meerschaum medium 15 is filled with in described second-stage treatment tank 2, water shoot 16 is provided with bottom second-stage treatment tank 2.
Embodiment 2: identical with above-described embodiment 1, the wherein downward-sloping setting of above-mentioned aeration head 11, and and in 45 degree of angles between aeration tube 10.
Sewage enters in coagulation tank 1 from water inlet pipe 4 by the utility model, by outer bound pair aeration tube 10 air feed, aeration head 11 is downward aeration in coagulation tank 1, solid particulate is rushed at piston 7, simultaneously piston 7 moves upward extruding, sewage is upwards pushed away, make sewage by rising pipe 6 discharged to second-stage treatment tank 2, substantially increase the efficiency of solid-liquid separation like this, thus accelerate the processing efficiency of sewage, sewage enters after second-stage treatment tank 2 through rising pipe 6, owing to being filled with modified meerschaum medium 15 in second-stage treatment tank 2 and being provided with whipping appts 13, sewage constantly contacts with modified meerschaum medium 15 in constantly stirring, by physical adsorbability and the chemical adsorptivity of modified meerschaum medium 15, by the heavy metal contaminants absorption in sewage, final sewage is discharged by water shoot 16.
The utility model structure is simple, reasonable in design, the immobilized particles in sewage can be removed fast and effectively, and the heavy metal contaminants can removed in sewage, adopt modified meerschaum medium 15 simultaneously, sepiolite wide material sources, cheap, and can use be regenerated, greatly save decontamination cost and a large amount of natural resourcess, there is higher economic benefit.
