Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
When the novel composite sand filter is implemented specifically, the novel composite sand filter comprises a reaction inner cavity, wherein a buffer layer 1 is arranged on the top layer of the reaction inner cavity, the lower part of the buffer layer 1 is a horizontal plane 2, and corresponding water level scale marks are carved on the wall of the cavity; the lower part of the buffer layer 1 is provided with an electrode plate 4, the lower part of the electrode plate 4 is provided with a sand filter layer 5, the lower part of the sand filter layer 5 is provided with a novel material filter layer 6, the lower part of the novel material filter layer 6 is provided with a fine gravel layer 7, and the lower part of the fine gravel layer 7 is provided with a coarse gravel layer 8; the main body of the electrode plate 4 is an electric flocculation device, and is connected with a solar cell panel arranged outside the device through a power line, and the power supply is realized through the solar cell panel; the novel material filtering layer 6 takes titanium dioxide powder loaded by iron as a substrate;
An electromagnetic valve port is formed in the wall of one side of the coarse gravel layer 8, and the electromagnetic valve port is connected with a water outlet 3 through a pipeline.
Porous titanium dioxide powder and ferric salt activated carbon composite materials are added into the novel material filtering layer 6, activated carbon adsorption is used as a main means for filtering pollutants, and efficient filtering of organic pollutants and heavy metals is achieved by combining electric flocculation.
The working principle of the utility model is as follows: the device takes iron-loaded titanium dioxide powder as a substrate and relies on electric flocculation, so that heavy metal substances in water can be efficiently filtered. The solar cell panel covered by the device can supply power to the electric flocculation device, and the requirement of sustainable development is met. In the filtration of organic micropollutants, the active carbon adsorption is taken as a main means, and the high-efficiency filtration is realized through the strong interaction between the active carbon and organic matters.
The activated carbon adsorbent has a strong adsorption force by utilizing the rich microporous structure and a high specific surface area, and can be used for treating toxic and harmful substances in water. The titanium dioxide (TiO) has photocatalytic degradation property, can degrade organic matters in water, loads TiO2 on the activated carbon, increases the photocatalytic performance on the original adsorption performance of the activated carbon, and can effectively improve the removal rate of the organic matters in the drinking water.
In the electric flocculation process, alloy metal such as aluminum, iron and the like is used as a main electrode, an electrochemical reaction is generated under the action of an external pulse high voltage, electric energy is converted into chemical energy, a metal cation flocculating agent is generated by a sacrificial anode metal electrode, and pollutants are separated from a water body through coagulation, flotation, reduction and oxidative decomposition, so that the water body is purified.
The device comprises three main improvements:
(1) the cheap active carbon improves the filter material;
(2) an electric flocculation device capable of effectively absorbing arsenic (As);
(3) the solar cell panel can continuously provide electric energy for the electric flocculation process.
During the initial test period of the sand filter, the arsenic removal rate of the filter medium layer of TiO2 coating active carbon with the thickness of 1cm after being combined with the electric flocculation process reaches 99.5%, the phosphorus removal rate reaches 94.5%, and the ammonia nitrogen removal rate reaches 88%, and the filter is expected to provide higher filtering capacity compared with the traditional filter.
