Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] see figure 1 , the embodiment of the present invention provides a technical solution: a pig farming wastewater treatment method, specifically comprising the following steps:

[0025] S1. Use manual manure cleaning. The pig manure in the pig house is manually cleared and transported to the treatment site, and then the pig house is washed with clean water. Some pig urine and solids in the pig house are washed to the sewage pipe together, and then passed t...

Abstract

The invention discloses a pig breeding wastewater treatment method. The method specifically comprises the following steps: S1, manually cleaning manures, manually delivering pig manures in a pig houseto a treatment field, then washing the pig house with clean water, flushing pig urine and solids in the pig house into a blow-off pipe together, removing hair and excrement residues in sewage by a grid sieve, then centrifuging the sewage by a horizontal centrifuge, finally, filtering, introducing the sewage into a primary sedimentation tank, precipitating fine suspended matters, adding a certainamount of a flocculating agent again, and directly transporting excrement residues and excrement residues, which are manually cleared and transported in the pig house to an excrement stacking tank. The invention relates to the technical field of wastewater treatment. According to the pig breeding wastewater treatment method, odor generated in the pig breeding wastewater treatment process can be treated to a certain extent in the modes such as microbial metabolic degradation, and the like, the overall deodorization effect is greatly improved, harm of the odor to the surrounding environment andresidents is avoided, and the deodorization procedure is easy to operate.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for treating wastewater from breeding pigs. Background technique [0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. The process of separating pollutants in wastewater or converting them into harmless substances. Pig farming is very common in our country, and the national demand for pork is very large. In the process of pig breeding, a large amount of wastewater will be produced. Pig farm wastewater mainly comes from pig manure, pig urine and washing water from breeding grounds. Sewage is rich in nitrogen, phosphorus, organic matter, and high-suspended solids. It is a kind of high-concentration organic wastewater. The existing pig breeding wastewater treatment methods are relatively mature...
