Description

A water cellar water purification device using a biological slow filter module

technical field

The utility model relates to a water cellar water purification device, in particular to a water cellar water purification device using a biological slow filtration module.

Background technique

As one of the main forms of decentralized water supply projects, water cellars are widely used in the southeast coast and northwest hilly areas of our country. However, although it has been widely used for many years, the safety of the water cellar has been difficult to be guaranteed.

The current water cellar mainly has the following defects:

(1) The water quality of ordinary cellar water is very poor, and the content of COD, total phosphorus, selenium, mercury, and E. coli exceeds the standard.

(2) The vast majority of water cellars are disinfected with chlorine gas, which easily produces trihalomethanes, haloacetic acids and other disinfection by-products, causing secondary pollution. In the case of using rubber and plastic water cellars, strong oxidizing disinfectants such as chlorine will also react with the carbon-carbon double bonds in the water cellar, increasing the organic content of the cellar water and reducing the service life of the water cellar.

(3) Due to the structural limitation of water entering and taking water from the top of the water cellar, the water at the bottom of the water cellar hardly flows and becomes "dead water", which is extremely easy to breed microorganisms.

(4) Since the water cellar has no control over the water inflow, livestock feces, firewood, domestic garbage, chemical fertilizers, pesticides, etc. attached to the ground enter the water cellar under the action of rainwater, causing sensory and toxicological indicators to exceed the standard, resulting in water pollution. Cellar water quality is difficult to guarantee.

detailed description

Below in conjunction with accompanying drawing 1 to 5 the utility model is described further.

Referring to Fig. 1, a cellar water purification device using a biological slow filter module, the main body of the device is a reinforced concrete structure, including: a cellar body 1, a water intake device 2, a biological slow filter module 3 and an initial rain discharge device 4.

The rainwater flowing through the ground enters the sump 41 after being filtered by the stagnation grid plate 44 and the water-permeable packing layer 411 . The rainwater after the first rain abandonment flow flows to the water collection cellar 11 by the water inlet pipe 45 . The water collection cellar 11 is designed as a square cylinder, and the concave surface is designed as a detachable sedimentation tank 113 to gather the sediment in the water collection cellar 11 to reduce the risk of blockage of the biological slow filter module 3. At the same time, the concave surface is designed as Detachable, the concave surface can be taken out as a whole for cleaning during dredging. The top of the water collection cellar 11 has a water collection cellar cover plate 111, and the water collection cellar emptying pipe 112 is deep into the water from the top of the water collection cellar 11, and water samples can be taken from the top, which is convenient for maintenance. The water in the water collection cellar 11 enters the biological slow filtration module 3 under the action of the water head difference. The water purified by the biological slow filter module 3 enters the water purification cellar 12 . Equally, clean water cellar 12 tops have clean water cellar cover plate 121 and clean water cellar emptying pipe 122, also have water intake device 2 at the top, conveniently purified water is taken out.

Referring to Fig. 2, the first rain abandonment flow device 4 comprises a sump 41 and an abandoned rain chamber 42 adjacent to each other up and down by a middle baffle 43, the middle baffle 43 is provided with a through hole 431, and the bottom of the through hole 431 is provided with a limiter. The position net 432 and the limit net 432 are equipped with a floating ball 433 and a water blocking plate 434 fixed on the top of the floating ball and capable of covering the through hole. The top of the sump 41 is provided with a retardation grid 44 covering the sump, the top of the sump 41 is a horizontally arranged water-permeable filler layer 411, and the bottom of the rain-discarding chamber (42) is a horizontally arranged permeable concrete layer 421; the sump 41 A water inlet pipe 45 for diverting the rainwater inside to the cellar body 1 is arranged on the outside. The upper side of the middle partition 43 is provided with a water-proof trap door 435 capable of covering the through hole 431 , and one end of the water-proof trap door 435 is rotatably connected to the upper side of the middle partition 43 .

The stagnation grid 44 is mesh-shaped, installed on the ground, and can be disassembled. The permeable filler layer 411 is placed in the metal or plastic mesh and can be taken out together with the metal or plastic mesh. The diameter of the floating ball 433 is slightly larger than the diameter of the through hole 431, and it can only move up and down under the limit of the limit net 432. The water inlet pipe 45 is located outside the sump 41 . After the rainwater collects on the ground, it flows into the sump 41 through the stagnation grid 44 and the permeable packing layer 411 . Under the action of the blocking grid 44, larger pollutants such as firewood, plastic bags, and fallen leaves are blocked outside the device to avoid blocking the device. The water-permeable packing layer 411 is composed of crushed stones or brick chips, and is placed in the metal mesh cover to play a filtering role. In the initial stage of rainfall, the initial rainwater carrying a large amount of fertilizer and sediment directly enters the rain disposal chamber 42 through the through hole 431 on the middle partition 43, enters the soil through the permeable concrete layer 421, and is removed together with the fertilizer and pesticide it carries. When the rainfall reaches a certain value, the floating ball 433 floats up, and the water blocking plate 434 on the floating ball blocks the through hole 431, and the rainwater enters the water collection cellar 11 through the water inlet pipe 45. When the dry season, the water-proof movable panel door 435 can be closed to block the through hole 431, so that all rainwater can be collected into the water collection cellar 11.

Referring to FIG. 3 and FIG. 4 , the biological slow filter module 3 is composed of a metal mesh housing 32 , a filter packing block 31 and a support column 33 to prevent deformation of the metal mesh housing 32 .

The filter packing block 31 is placed in the metal mesh housing 32 and can be taken out freely. The metal mesh housing 32 adopts a pluggable design, and there are slides on the walls on both sides of the biological slow filter module 3. In the dry season, the biological slow filter module 3 can be pulled out to clean and replace the filter material . The interior of the bio-slow filter module 3 is filled with river sand filter substrate 312. In order to prevent the sand particles from slipping out, the mesh diameter of the metal mesh housing 32 should be smaller than the average diameter of the substrate particles. At the position where the biological slow filter module 3 is close to the metal mesh housing 32, gravel 313 whose diameter is obviously larger than the matrix particles is arranged to play a supporting role. An activated carbon layer 311 made of activated carbon is added to the river sand filter matrix layer 312 . Under the effect of water head difference, the water flow passes through the biological slow filter module 3, and a layer of biofilm composed of microorganisms and algae will be formed on the surface of the internal filter material of the biological slow filter module 3. The main components of the biofilm are bell worms, bell worms, rib worms and so on. In order to adapt to the water level in different periods, reduce the pressure of the inner packing of the biological slow filter module 3 on the outer metal mesh shell 32, and avoid its deformation, the biological slow filter module 3 is designed as a brick. In actual use, multiple biological slow filter modules 3 are stacked together to form a slow filter device. Increase the number of biological slow filter modules 3 in wet seasons, and reduce the number of biological slow filter modules 3 in dry seasons. When the internal filter material of the biological slow filter module 3 is clogged, the biological slow filter module 3 is pulled out from the water cellar, the biofilm is scraped off, and then rinsed.
