(4) the clean wastewater treated by the sewage treatment tank is led to a pig farm and is used as clean water of the pig farm; and collecting the biochar sludge adsorbed N, P by the sewage treatment tank to prepare the carbon-based fertilizer.
2. The resource utilization production device for the piggery sewage according to claim 1, characterized in that: in the step (2), bamboo chips are mixed into the bamboo chip mixing port, and the dried excrement is mixed with the bamboo chips in the mixing machine and stirred uniformly; in the step (3), the sewage treatment tanks are divided into two groups, namely a first sewage treatment tank and a second sewage treatment tank; the electromagnetic valves of the first sewage treatment tank and the second sewage treatment tank are controlled by the single chip microcomputer to be alternately switched on and off, so that when biochar is added into the adsorption tank of the first sewage treatment tank and stands still, separation liquid can continuously enter the second sewage treatment tank, when biochar is added into the adsorption tank of the second sewage treatment tank and stands still, the adsorption tank of the first sewage treatment tank can continuously enter the separation liquid after adsorption and cleaning, so that the two groups of sewage treatment tanks are mutually matched, and the separation liquid is continuously treated; in the step (4), the clean water of the pig farm and the new manure are returned to the device again for the treatment of the next period.
3. The pig farm sewage resource utilization production device as claimed in claim 2, wherein: when biochar is added into an adsorption tank of the first sewage treatment tank and stands, all electromagnetic valves of the first sewage treatment tank are closed, and a second electromagnetic valve, a second water pump, a fifth electromagnetic valve and a fourth water pump of the second sewage treatment tank are opened; when the adsorption tank of the second sewage treatment tank is added with the biochar and is kept stand, all electromagnetic valves of the second sewage treatment tank are closed, and the first electromagnetic valve, the first water pump, the fifth electromagnetic valve and the fourth water pump of the first sewage treatment tank are opened.
4. The resource utilization production device for the piggery sewage according to claim 1, characterized in that: in the step (3), adding biochar into the adsorption tank, aerating by an aeration disc, and stirring by a stirring device; the aeration disc forms an angle of 30 degrees with the horizontal plane, so that the resistance of water can be reduced, bubbles are not easy to combine, and a circulation mixing effect is formed in aeration, so that the activity of flora is enhanced, and the degradation capability and the sedimentation ratio are improved; the temperature of the interior of the adsorption tank is controlled by a temperature control device to promote the adsorption of the biochar; after the settling chamber is used for a period of time, sludge cleaning can be carried out: the high-pressure air pipe only works at the moment, the air outlets for blowing high-pressure air upwards and downwards blow the high-pressure air out, the high-pressure air is utilized to assist in disturbing the sludge, the sludge is discharged from the sludge discharge pipe at last, and the discharged sludge can be conveyed to the excrement dry-wet separator for circulation.
