The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1, the present embodiment provides a sewage treatment system for a pig farm, which comprises at least one pig farm 100, a third sewage drainage channel 230 disposed outside the pig farm 100, and an outdoor sewage treatment system. In other embodiments, a plurality of pigsties 100 may be arranged side by side, and the third sewage drain 230 is arranged side by side in parallel with the pigsties 100, and the third sewage drain 230 is arranged outside the pigsties 100. As shown in fig. 2 and 3, at least one row of pigsty 10 is provided in each pigsty 100, and at least one row of pigsty 10 is provided in each row of pigsty 10. In this embodiment, the excrement and sewage generated by the pigs in each piggery 100 are collected in the third sewage draining channel 230 and then discharged into the outdoor sewage treating system through the third sewage draining channel 230, so that the excrement and sewage are firstly subjected to solid-liquid separation by the outdoor sewage treating system and then are subjected to purification treatment.
In the present embodiment, as shown in fig. 2 and 3, an indoor sewage collecting system is provided in each pigsty 100. Wherein, indoor sewage collection system includes a plurality of first sewage pipes 210 and second sewage pipes 220, and the quantity of first sewage pipes 210 is the same with the row number of swinery 100, and every row of swinery 100 corresponds and is provided with one first sewage pipes 210, just so makes every row of swinery 100 below all be equipped with one first sewage pipes 210, is convenient for collect the excrement and urine of the interior pig of swinery 10 and clear up the produced sewage of swinery 10. In addition, if the number of the swinery 10 in each row of swinery 10 is greater than or equal to two, the first drainage channel 210 needs to be arranged below each swinery 10, that is, one end of the first drainage channel 210 is located on one side of each row of swinery 10, and the other end of the first drainage channel 210 needs to cross over the other side of each row of swinery 10. In this embodiment, a second drainage channel 220 is provided in each pigsty 100, and the second drainage channel 220 is used for collecting the excrement and sewage collected in all the first drainage channels 210 in the same pigsty 100, and the excrement and sewage are drained out of the pigsty through the second drainage channel 220. Therefore, in a general arrangement of the pigsty 100, the second drainage channel 220 is generally arranged on the access way of the pigsty 100. Preferably, the first sewage draining channel 210 and the second sewage draining channel 220 are communicated in a vertical crossing manner, so that the construction of the first sewage draining channel and the second sewage draining channel is facilitated, and the interior of the pigsty 100 is relatively beautiful. In addition, a second flushing water pipe (not shown) may be provided at an end of the second sewage drain channel 220 remote from the third sewage drain channel 230 in order to accelerate discharge of the excrements and sewage in the second sewage drain channel 220.
In some embodiments, it is sometimes impossible to wash the pig manure in the first sewerage channel 210 only by using the sewage generated when the piggery 10 is cleaned, and therefore a first flushing pipe (not shown) is required to be arranged at the end of the first sewerage channel 210 far from the second sewerage channel 220, so as to flow the water in the first sewerage channel 210. In addition, the installation of the first flushing pipe can also clean the excrement generated by the pig in time (at the moment, the pig is required to generate the excrement above the grating of the first sewage draining channel 210, so that the excrement directly falls into the first sewage draining channel 210), and the living environment of the pig is improved to a certain extent. In addition, side chambers 110 may be respectively disposed at both sides of the pigsty 100, and a spraying system (not shown) may be disposed in the side chambers 100, the spraying system may sterilize air entering the side chambers 110, and a ventilation fan may be installed on an outer sidewall of the side chambers 110 to draw air outside the pigsty 100 into the side chambers 110. Meanwhile, one end of the first sewage drain channel 210, which is far away from the second sewage drain channel 220, is disposed in the lateral chamber 110, and one end of the first sewage drain channel 210, which is far away from the second sewage drain channel 220, is close to the outer side wall of the lateral chamber 10. Thus, the air drawn into the side chamber 110 by the ventilation fan is continuously increased in pressure, and then enters the pigsty 100 through the first sewage drainage channel 210, so that the probability that the pigs are sick can be effectively reduced. As described above, in order to achieve the above object, it is necessary to keep the side chamber 110 in a sealed state except for the ventilation fan when the side chamber is in use, so that air can smoothly enter the pigsty 100 through the first drainage channel 210.
In order to accelerate the renewal of air in the pigsty 100, an air shaft 400 may be provided in the pigsty 100, and a fan may be installed in the air shaft 400. Specifically, a plurality of vent holes are arranged on the air shaft 400, and the vent holes are close to the top of the pigsty 100, so that hot air (which rises after being heated) at the top of the pigsty 100 can enter the air shaft 400 through the vent holes and then be discharged out of the pigsty 100, wherein the air is gathered at the top area of the pigsty 100 than the hot air in the pigsty. In addition, if only the air shaft 400 is used to exhaust air, a plurality of air shafts 400 need to be constructed, which increases the construction cost of the pigsty 100, compared to some large pigsties 100. Therefore, for such a large pig house 100, the air shaft 400 may be utilized and the exhaust fan may be installed on the top of the pig house to exhaust air in time, or the air shaft 400 may not be installed and only the exhaust fan may be installed on the roof.
In other embodiments, the bottom of the first sewerage channel 210 may be sloped, and the end of the first sewerage channel 210 connected to the second sewerage channel 220 may be the lowest. Is convenient for discharging sewage and excrement. Similarly, the bottom of the second sewage drain 220 may be sloped, and the end of the second sewage drain 220 connected to the third sewage drain 230 is lowest. Preferably, the depth of the first sewage drain 210 may be set to be smaller than the depth of the second sewage drain 220, so that the manure and sewage of the first sewage drain 210 can be easily introduced into the second sewage drain 220.
In this embodiment, the outdoor sewage treatment system comprises a solid-liquid separation and purification system, the third sewage draining channel 230 transports the excrement and sewage in the second sewage draining channel 220 into the solid-liquid separation and purification system, and the excrement and sewage can be separated and purified by the solid-liquid separation and purification system. Preferably, the solid-liquid separation purification system includes a settling tank 310, a wastewater tank 320, and a solid-liquid separator 340, and the solid-liquid separator 340 is a device commonly used in wastewater treatment, and thus, the specific structure thereof will not be described in this application.
