Abstract
The invention provides a removing method of exceeding iron-manganese heavy metal in underground seawater. The removing method comprises the following steps: underground seawater is pumped by a water pump to enter a pretreatment device for removing particles in the underground seawater; after the particles are removed, the underground seawater is led to an ozone treatment pool for ozone aeration treatment, and the exceeding heave metal in the underground seawater are oxidized into water-insoluble precipitates by virtue of the strong oxidizing property of ozone; the treated seawater is adsorbed and filtered by a sand filter tank filled with medium manganese sand; after being filtered with the medium manganese sand, the seawater is aerated in an aeration pool so as to remove the exceeding iron-manganese heavy metal in the underground seawater. The removing method is economical, applicable, high in treatment efficiency and convenient to promote. Devices needed by the removing method are low in construction cost, the operation is simple and easy to learn, and operators do not need special training. The removing method is specifically suitable for mariculture enterprises.

Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of underground sea water ferrimanganic heavy metal removal method that exceeds standard.
Background technology
Underground water is the important component part of water resources, and within one very long period, because the water yield is stable, water quality is good, is one of the important water source in agricultural irrigation, industrial and mineral and city.And in recent years, application and popularization along with turbot " warmhouse booth+deep-well seawater " industrialized aquaculture pattern, make full use of the water temperature homoeostasis of underground water, successfully solved in some fish industrialized cultures and need to heat up and survive the winter in winter, cooling in summer crosses the problem that summer aspect is brought, greatly saved production cost, some famous and precious fish are as turbot, Cynoglossus semilaevis, the aquacultures such as filefish are rapidly developed in coastland, but the underground water heavy metal in most areas is as severe overweights such as ferrimanganics, some areas are (as Laizhou, Shandong, Changyi, Ganyu, Jiangsu, the ground such as Dalian) iron in underground water, manganese index surpasses respectively 18 times and 210 times of aquaculture water code requirement, the breeding water heavy metal that exceeds standard can affect the normal growth of fish, the fish speed of growth is slowed down, even cause its death by suffocation, therefore how the removal underground sea water of the economical and efficient heavy metal that exceeds standard becomes the matter of utmost importance that numerous breeding enterprises face.
At present in water, heavy metal removal method has chemical precipitation method, ion exchange method, By Bubble-floating Method, biotechnology method, electrolytic process etc., and aforesaid method respectively has advantage, but also there is secondary pollution accordingly, complex process, the problem such as cost is high, processing efficiency is low.
Summary of the invention
For addressing the above problem, the underground sea water of the object of the present invention is to provide a kind of economic and practical, highly-efficient treatment, being convenient to the to promote ferrimanganic heavy metal removal method that exceeds standard.
Technical scheme provided by the invention is: a kind of underground sea water ferrimanganic heavy metal removal method that exceeds standard, comprises the steps:
Step 1: the underground sea water extracting by water pump enters pretreatment unit, removes particulate matter by precipitation;
Step 2: the underground sea water of removing particulate matter is passed into and carries out ozonation aerated processing in ozonize pond;
Step 3: the seawater after ozonation aerated processing carries out adsorption filtration through filling the sandfiltration pot of ripe matter manganese sand;
Step 4: the seawater after sand filtration enters aeration tank Air Exposure, thus the removal to the heavy metal that exceeds standard in underground sea water completed.
Optimize, the ozone source of carrying out ozonation aerated processing in step 2 is ozonizer, and the ozone that ozonizer produces passes into ozonize pond by jet-pump, makes the uniform and pending sea water mixing of ozone.
Optimize, fill the manganese sand that particle diameter is 0.5～1.5mm in the sandfiltration pot in step 3, the seawater after ozonation aerated processing passes through manganese layer of sand from top to bottom.
Optimize, the manganese sand in the sandfiltration pot in step 3, fills according to the order that particle diameter increases gradually from top to bottom.
Optimize, the bottom of the pretreatment unit in step 1 arranges wash water valve, and the particulate matter that precipitation is produced is regularly discharged.
Optimize, the sandfiltration pot bottom in step 3 is provided with wash water valve, regularly the sewage retaining and the too much sedimentary manganese sand of absorption is cleared up, and fills new manganese sand.
The invention has the beneficial effects as follows:
1. facilities and equipment of the present invention is cheap simple.Facilities and equipment required for the present invention, buys or builds cheapness simply as ozonizer, jet-pump, sandfiltration pot, ozonize pond, aeration tank etc., and floor space is less, and construction cost is low.
2. convenient operation and management of the present invention, level of automation is high.The inventive method, without complicated physics, chemical operation process, gets final product operational administrative without Special Training, and level of automation is high, only needs periodic cleaning throw out and changes manganese sand.
3. environmental friendliness of the present invention, highly-efficient treatment.The throw out producing after heavy metal oxidation in the present invention or the manganese sand of its absorption etc. can periodic cleanings, and fixed point is placed, pollution-free to surrounding environment; The inventive method highly-efficient treatment, reaches good removal effect to the underground sea water heavy metal that exceeds standard, and meets the fishery water standard of national regulation.
