Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to an algae removal structure for a water plant. Background Art
[0002] Drinking water safety has always been a hot topic of social concern and a core guarantee for water supply production. In recent years, my country has experienced a number of water crisis incidents caused by algae outbreaks in water sources, which has attracted widespread public attention. Under high nitrogen and phosphorus concentrations and suitable temperature and light, algae will proliferate in large numbers in water bodies. After algae die, they will release odor-causing substances such as mercaptans and sulfides, which puts high demands on the treatment process of water plants. If the treatment is not in place, the tap water will have an odor, which seriously affects the safety of water supply. In particular, reservoirs with small storage capacity, shallow water, and high nitrogen and phosphorus concentrations are prone to eutrophication problems, which will cause seasonal outbreaks of algae under suitable temperature and light conditions.
[0003] At present, the algae control strategies adopted by most water plants are comprehensive measures such as adding free chlorine, potassium permanganate and powdered activated carbon at the water inlet. These strategies are short-term algae killing or odor removal methods after an outbreak of algae such as green algae and red algae. They do not suppress the problem of algae outbreaks from the root, are costly and have limited effects. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] Please refer to Figure 1 As shown, an algae removal structure of a water plant includes a water tank and an algae removal plate, wherein a water inlet is provided on one side of the water tank and a water outlet is provided on the other side thereof, a slot is provided on the inner side of the water tank, both ends of the algae removal plate are slidably engaged in the slot, the water outlet and the water inlet are respectively located on both sides of the slot, the algae removal plate includes a metal frame, filter nets are provided on both end surfaces of the metal frame, and a filter element for filtering algae is provided between the filter nets.
[0021] In this embodiment, the filter element comprises an alkaline ceramsite layer, a zeolite layer and a feldspathic sandstone layer arranged in parallel in sequence, wherein the thickness ratio of the alkaline ceramsite layer, the zeolite layer and the feldspathic sandstone is 1:3:1, and the particle diameters of the alkaline ceramsite layer, the zeolite layer and the feldspathic sandstone are 1 to 5 mm.
[0022] The water flows into the water tank through the water inlet, passes through the algae removal plate, is filtered, and then flows through the water outlet. During this process, the alkaline ceramsite layer is filled with ceramsite, which is effective in removing green algae and turbidity, and has ion exchange, removal of harmful substances, decomposition of heavy metals, as well as pH adjustment and water purification to adjust water quality. Because it is weakly alkaline, it can improve the purity of water, adjust hardness, maintain oxygen content, reduce BOD and COD, and increase dissolved oxygen.
[0023] The zeolite layer is filled with zeolite particles. Among natural minerals, zeolite (Si, Al) is a microporous aluminum silicate component that can effectively remove green algae, red algae and turbidity. In particular, zeolite has an excellent ability to adsorb nitrogen oxides (NOx). Oxidation and reduction reactions occur simultaneously during the adsorption process, and hydrogen peroxide (H2O2) is produced during the reaction. However, the hydrogen peroxide generated at this time is reduced to an unstable state and produces oxygen. The amount of dissolved oxygen in the water increases, inhibiting the growth of suspended matter such as green algae.
[0024] The feldspar sandstone layer is mainly filled with feldspar sandstone, which is an aluminum layered silicate mineral containing potassium, sodium and calcium. It has an effective removal effect on arsenic and cesium. The adsorption test results show that Pb, Cu and Fe are 99%, 98% and 97% respectively. It can be adsorbed within 1 hour and used as a heavy metal adsorbent for water purification.
[0025] Therefore, after the water flows through the algae removal plate, the algae in the water can be physically filtered through the alkaline ceramsite layer, zeolite layer and feldspar sandstone layer. At the same time, the water quality in the water can be changed to inhibit the growth of suspended matter such as green algae, thereby achieving the purpose of algae removal.
[0026] It should be noted that in order to facilitate the replacement of the algae removal board, the utility model also changes the metal frame into a stainless steel anti-corrosion frame, and provides a handle on the top of the metal frame. Through the handle, it can be quickly pulled out of the card slot of the water tank for replacement, which is convenient and quick to use.
[0027] Among them, an activated carbon filter is arranged on the water outlet pipe to filter out heavy metals that may be contained in the discharged water eliminator, so as to prevent the pollution of water by heavy metals in advance, and an inlet electromagnetic control valve is arranged on the water inlet pipe.
[0028] The utility model discloses an algae removal structure for a water plant, which is installed at the front end of the water plant. That is, the tap water passes through the algae removal structure of the present application before being processed, and the algae in the water flow passing through the water tank are filtered by an algae removal plate to reduce the algae content, thereby avoiding algae outbreaks and affecting water quality during the subsequent tap water treatment process.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
