In the use process of the rural livestock-raising sewage treatment system, when the average air temperature is high in summer or autumn and plants are in a metabolism vigorous period, the reclaimed water containing ammonia nitrogen and phosphorus obtained after the centralized treatment of the sewage of the breeding base is sent into the constructed wetland 400, and after the ammonia nitrogen and phosphorus content in the reclaimed water is reduced through physical, biological and chemical actions, the reclaimed water is discharged or recycled. When the average air temperature is low in winter and spring and plants are in a slow metabolism or non-metabolism period, the reclaimed water containing ammonia nitrogen and phosphorus obtained after the centralized treatment of the sewage of the culture base is sent into a reclaimed water storage pool 210 for storage, and after the air temperature is increased and the plant metabolism is recovered, the reclaimed water stored in the reclaimed water storage pool 210 is sent into an artificial wetland 400 for treatment and then is discharged or recycled. By arranging the reclaimed water storage pool 210, when the average air temperature is low and the plant metabolism is not active, the reclaimed water is temporarily stored, the reclaimed water can be recycled to the cultivation base for use, when the air temperature rises, and the plant metabolism is vigorous, the reclaimed water is intensively treated, so that the problem that the constructed wetland 400 cannot normally operate due to the influence of the air temperature and the plant growth period in the north of China is effectively solved, the treatment effect of the reclaimed water is ensured, and the standard treatment of the waste water of the cultivation base is ensured.
For example, the reclaimed water storage pool 210 is divided into a main storage pool 210-1, at least one auxiliary storage pool 210-2, and at least one tertiary storage pool 210-3, the upper portions of the plurality of auxiliary storage pools 210-2 are all communicated with the main storage pool 210-1 through a reclaimed water overflow pipe 212, and the plurality of tertiary storage pools 210-3 are all connected with the at least one auxiliary storage pool 210-2 through the reclaimed water overflow pipe 212. After rural sewage is treated, reclaimed water is discharged into the main storage pool 210-1 nearby, after the main storage pool 210-1 is filled, the reclaimed water is split into the auxiliary storage pool 210-2 through the reclaimed water overflow pipe 212, and after the auxiliary storage pool 210-2 is filled with water, the reclaimed water is split into the tertiary storage pool 210-3 through the reclaimed water overflow pipe 212.
It will be appreciated by those skilled in the art that it may be optional to construct only the primary storage pool 210-1 and the secondary storage pool 210-2, as the case may be, and not the tertiary storage pool 210-3. It may also be optional to build a four-level storage pool, a five-level storage pool, etc. on the basis of the three-level storage pool 210-3. The second level reclaimed water storage pool 210 and the subsequent levels of reclaimed water storage pools 210 may be provided in plurality so as to form a reclaimed water storage network.
In the above embodiment, the reclaimed water is sequentially split into the auxiliary storage pool 210-2 and the tertiary storage pool 210-3 from the near main storage pool 210-1, on one hand, only a group of water inlet pumps are needed to be arranged or water is directly fed in a self-flowing mode, and the pump does not need to have excessive lift, so that the number and the running time of the pump are reduced, and the construction cost and the running cost are reduced. On the other hand, in the whole storage process of the reclaimed water, the reclaimed water in each reclaimed water storage pool 210 is in a flowing or disturbed state, so that the fluidity of the reclaimed water is enhanced, and the reclaimed water is prevented from being stored for a long time in a static state to form dead water, so that secondary pollution is caused.
During storage of reclaimed water, because the reclaimed water level in the main storage pool 210-1 is always higher than the reclaimed water level in the auxiliary storage pool 210-2, the reclaimed water cannot flow back to the main storage pool 210-1 through the return pipe 213 under the action of static pressure. During the draining process, water can be pumped from the main storage pool 210-1 only, when the level of the reclaimed water in the main storage pool 210-1 is reduced to be smaller than the level of the reclaimed water in the auxiliary storage pool 210-2, the reclaimed water in the auxiliary storage pool 210-2 flows back to the main storage pool 210-1 through the return pipe 213 under the action of static pressure, and so on, when the level of the reclaimed water storage pool 210 in the previous stage is reduced to be smaller than the level of the reclaimed water storage pool 210 in the next stage, the reclaimed water in the reclaimed water storage pool 210 in the next stage flows back to the reclaimed water storage pool 210 in the previous stage until the water in the water storage pool 210 in the next stage is pumped. Preferably, the bottom of the latter-stage reclaimed water storage pool 210 is higher than the bottom of the former-stage reclaimed water storage pool 210 so that reclaimed water in the latter-stage reclaimed water storage pool 210 can be completely drained.
In the above embodiment, the return pipe 213 and the non-return assembly 214 disposed at the bottom of the reclaimed water storage pool 210 can discharge water from one or a few reclaimed water storage pools 210, so as to reduce the investment on machine pump equipment and facilitate the unified treatment of reclaimed water.
In a preferred embodiment, at least one multifunctional auxiliary pipe 215 is disposed in the middle of the reclaimed water storage pool 210, the multifunctional auxiliary pipe 215 is connected to at least one reclaimed water storage pool 210 close to the water storage well 200, and a stop assembly 216 is disposed on the multifunctional auxiliary pipe 215.
That is, the upper stage reclaimed water storage pool 210 communicates with the lower stage reclaimed water storage pool 210 not only at the upper and lower portions thereof, but also at least one multifunctional auxiliary pipe 215 for communicating the upper stage reclaimed water storage pool 210 with the lower stage reclaimed water storage pool 210 is provided at the middle portion thereof. Normally, the shut-off assembly 216 is closed and no water can flow through the multifunction auxiliary tube 215. In one case, to facilitate the flow of water between the water storage tanks 210 of each stage, the stop assembly 216 is opened in time to allow the water in the water storage tank 210 of the upper stage to flow into the water storage tank 210 of the lower stage, and to replenish fresh water in the water storage tank 210 of the lower stage, so as to prevent the water in the water storage tank 210 of the lower stage from flowing for a long time to form dead water, thereby causing secondary pollution. Or in yet another embodiment of the present utility model, when the water pressure is insufficient to open the check assembly 214, the shut-off assembly 216 may be opened to draw water from the lower level water reservoir 210 into the upper level water reservoir 210 in advance. In yet another case, when it is desired to utilize nearby water from the next-level water storage pool 210, the shut-off assembly 216 may be opened so that water in the previous-level water storage pool 210 is introduced into the next-level water storage pool 210 in advance for nearby use.
In some embodiments, the check assembly 214 is a one-way valve. Referring to fig. 3, in one preferred embodiment, for facilitating construction and reducing construction costs, the check assembly 214 includes a receiving member 2141 and a check gate 2142 disposed at the water outlet end of the return pipe 213, wherein the upper end of the check gate 2142 is hinged to the receiving member 2141 or the wall of the water storage well, and the check gate 2142 can be covered on the receiving member 2141. In the water inlet state, the non-return gate 2142 is tightly attached to the receiving member 2141 under its own weight and water pressure, so as to prevent water from entering the water storage pool 210 in the next stage. In the water-out state, when the liquid level of the water storage pool 210 in the upper stage falls below the liquid level of the lower stage and the back pressure exerted by the water in the water storage pool 210 in the lower stage on the check gate 2142 is greater than the sum of the pressure exerted by the water in the water storage pool 210 in the upper stage and the gravity of the check gate 2142, the check gate 2142 is separated from the receiver 2141 and the water in the water storage pool 210 in the lower stage returns to the water storage pool 210 in the upper stage.
Preferably, to prevent the non-return gate 2142 from being opened smoothly, an auxiliary float 2143 is further provided on the non-return gate 2142, and the auxiliary float 2143 causes the non-return gate 2142 to be biased away from the receiver 2141. Under the action of water buoyancy, the non-return flashboard 2142 is always stressed by a force far away from the adapting piece 2141, so that when the liquid level of the water storage pool 210 in the previous stage is reduced to be lower than that of the water storage pool 210 in the next stage, the back pressure can be opened without overcoming the gravity of all the non-return flashboard 2142, and the smoothness of water flow is effectively ensured.
In one embodiment, the shut-off assembly 216 includes a shut-off ram disposed at an end of the multi-functional auxiliary pipe 215, the shut-off ram being capable of being lifted in a well depth direction. The shutoff gate is provided with a shutoff portion 2161, and the shutoff portion 2161 can be covered with an end portion of the multifunctional auxiliary pipe 215. Normally, the blocking portion 2161 is covered on the end of the multifunctional auxiliary pipe 215, and when the multifunctional auxiliary pipe 215 needs to be opened, the blocking shutter is lifted upward, so that the blocking portion 2161 is separated from the end of the multifunctional auxiliary pipe 215, i.e., the water storage pool 210 in the upper stage is communicated with the water storage pool 210 in the lower stage.
In this embodiment of the application, the rural livestock-raising sewage treatment system may further include a clean water storage pool 600, specifically, the water outlet pipeline of the constructed wetland 400 may be communicated with the water inlet pipeline of the clean water storage pool 600, the water outlet pipeline of the clean water storage pool 600 may be communicated with the clean water use pipeline of the farmer, and the water outlet pipeline of the clean water storage pool 600 may be communicated with the clean water use pipeline of the cultivation base. In some cases, such as in summer in north China, the reclaimed water generated after the sewage of the cultivation base is treated is sent to the constructed wetland 400 for further treatment, clean water is obtained after treatment, and the clean water is collected in the clean water storage pool 600 for recycling, for example, because the water outlet pipeline of the clean water storage pool 600 is communicated with the clean water using pipeline of the cultivation base, the clean water using pipeline of the cultivation base can be communicated with a drinking water tank and a medicine water tank of livestock and the like, so that the cultivation base is convenient for drinking by livestock.
Further, the number of the clean water storage pools 600 may be plural, and any one of the plurality of the clean water storage pools 600 is communicated with at least one clean water storage pool 600 close thereto. I.e. a plurality of clean water storage pools 600, at least two clean water storage pools 600 are communicated, on one hand, the clean water is conveniently guided to places with larger water demand. Preferably, the fresh water storage pool 600 may be connected in a similar manner to the medium water storage pool 210 to save floor space and reduce costs.
