Description

A device for collecting rainwater in arid areas

technical field

The utility model belongs to the technical field of rainwater storage devices, in particular to a rainwater storage device in arid areas.

Background technique

The scarcity of water resources is a global ecological problem, and how to save water resources is a major problem faced by mankind. For arid areas, water resources are even scarcer, and how to effectively use and collect rainwater resources is particularly important.

Most of the rainwater storage devices currently on the market have the following problems:

(1) Few of the existing rainwater collection and storage devices are specially designed for arid areas, and most of them are not suitable for use in arid areas.

(2) The existing rainwater collection and storage devices in arid areas are costly and ineffective, and the collected rainwater is turbid and cannot be used directly, so it is not popular.

Utility model content

The purpose of the utility model is to provide a rainwater storage device in arid areas to solve the problems of high cost, poor use effect and poor water purification effect of the prior art in arid areas.

In order to achieve the above-mentioned purpose of the invention, the technical scheme that the utility model takes is:

A rainwater collection device in arid areas is provided, which includes a water storage tank, a filter box, a clean water tank and a water storage tank sequentially connected by water pipes;

The water storage tank includes a cover body with an aperture and a water pump connected with a water pipe and arranged at the bottom of the tank body;

The filter box includes a filter layer arranged in the box;

The clean water tank includes a black cover body, a hydrolysis acidification pool and a microlysis pool arranged at intervals through a partition, and an adsorption layer is arranged above the microlysis pool.

Preferably, the hole diameter on the cover is 1-3 cm.

Preferably, the diameter of the hole on the cover is 2 cm.

Preferably, the filter layer includes an upper layer, a middle layer and a lower layer; the upper layer, the middle layer and the lower layer are all composed of pebbles or gravels; the radii of the pebbles or gravels in the upper layer, the middle layer and the lower layer decrease successively.

Preferably, the hydrolytic acidification pool is communicated with the microlysis pool through water pipes.

Preferably, the black cover is a curved cover.

The rainwater collection and storage device in arid regions provided by the utility model has the following beneficial effects:

(1) Large water storage capacity: The water storage tank is a box with a large enough capacity to collect a large amount of rainwater. In addition, the filter box, clean water tank and water storage tank can also store a large amount of rainwater to ensure that when it rains in arid areas Collect as much rainwater as possible.

(2) Good filtering effect: in arid areas, turbid rainwater usually contains leaves and sandstones. When the rainwater flows into the storage tank through the cover, the cover with holes will filter out leaves and sandstones with large diameters. Most of the water-insoluble solid impurities are removed through the filter layer, and the multi-level filter settings ensure the filter effect.

(3) Good water purification effect: the arc-shaped setting of the black cover body increases its surface area, and the black cover body setting can fully absorb sunlight and increase the temperature in the hydrolysis acidification pool and microlysis pool without additional heating devices. It can speed up the reaction rate in the purification box, save resources and ensure the water purification effect.

detailed description

Below in conjunction with accompanying drawing, the embodiment of the technical solution of the utility model is described in detail:

According to one embodiment of the present application, as shown in Figure 1, the rainwater collection device in the arid area of this program includes a water storage tank 2, a filter box 5, a clean water tank 7 and a water storage tank 12 connected in sequence by a water pipe 3;

The water storage tank 2 includes a cover body 1 with an aperture and a water pump 4 connected to the water pipe 3 and arranged at the bottom of the tank body;

The filter box 5 includes a filter layer 6 arranged in the box;

The clean water tank 7 includes a black cover body 9 , a hydrolytic acidification pool 8 and a microlysis pool 11 arranged at intervals through a partition, and an adsorption layer 10 is arranged above the microlysis pool 11 .

Wherein, the cover body 1 on the water storage tank 2 has an aperture of 1-3 cm, preferably 2 cm, which can effectively prevent leaves and large particles of sand from flowing into the box when rainwater passes through the cover body 1 .

Filter box 5 is provided with filtering layer 6, and filtering layer 6 comprises upper strata, middle stratum and lower stratum, and its upper strata, middle stratum and lower stratum are all made up of cobblestone or gravel, wherein the radius of cobblestone or gravel of each layer is the same, upper strata, The radii of the pebbles or gravels in the middle layer and the lower layer decrease in turn, which can effectively filter out most of the insoluble solid impurities, and the multi-level filter settings ensure the filter effect.

The purification box 7 is provided with a hydrolytic acidification pool 8 and a microlysis pool 11 connected by a water pipe 3, wherein the microlysis pool 11 is equipped with aerobic bacteria and anaerobic bacteria, and the rainwater treated in the hydrolysis acidification pool 8 enters the microlysis pool 11, first feed aerobic bacteria into the microlysis pool 11, and when the aerobic bacteria consume most of the oxygen in the pool and initially decompose the organic matter in the pool, then feed anaerobic bacteria to further decompose the organic matter in the pool.

The arc-shaped setting of the black cover body 9 on the purification box 7 can fully absorb sunlight, improve the temperature in the hydrolytic acidification pool 8 and the microlysis pool 11, and accelerate the rate of hydrolysis acidification and decomposition of organic matter. Adsorbent is housed on the adsorption layer 10, which can Toxic heavy metal ions are adsorbed and filtered.

Concrete process, when the turbid rainwater flows into the water storage tank 2, under the effect of the cover body 1 with the aperture, the leaves and the sand and gravel of large particles in the water are filtered, and the water pump in the water storage tank 2 is pumped under the action of the water pump 4 into the filter box 5, and then pass through the filter layers 6 arranged from large to small radii, and filter to remove water-insoluble solid impurities.

Under the action of the water pump, the water is pumped into the hydrolysis acidification tank 8, and the non-dissolved organic matter is intercepted and converted into dissolved organic matter. The water is pumped into the microlysis tank 11, and flows through the adsorption layer 10 to remove toxic heavy metal ions. Under the action of anaerobic bacteria, the dissolved organic matter is decomposed, and finally the water reaching the standard is pumped into the water storage tank 12 for storage for use.

The device is set up for arid areas, has low price and low cost, can collect a large amount of rainwater, and has strong practicability and popularization.

Although the specific implementation of the utility model has been described in detail in conjunction with the accompanying drawings, it should not be construed as limiting the scope of protection of this patent.
