Pig raising wastewater treating system

Abstract

The invention discloses a pig raising wastewater treating system, and belongs to the technical field of farm sewage treating, the pig raising wastewater treating system comprises a casing, a feed hopper is mounted at the top of the casing, a rotary cover is mounted on the inner side wall of the feed hopper, an atomizing nozzle is mounted at the top of the casing, and the atomizing nozzle is connected to the bottom of the inner side wall of a water tank through a pipeline and a water pump; a partition plate is welded to the middle of the inner side wall of the casing, a settling chamber is formed between one side of the inner side wall of the casing and the partition plate, a liquid chamber is formed between the other side of the inner side wall of the casing and the partition plate, and a centrifugal net disc is installed at the bottom of the settling chamber. The wastewater treating system can separate most suspended solids in wastewater. According to the pig raising wastewater treating system, large solids and precipitates in sewage can be separated from the sewage and then centrifugally dried, the odor removal effect of the pig raising wastewater treating system is good, and the situation that the sewage emits odor to the surrounding environment is improved.

Description

technical field [0001] The invention relates to the field of farm sewage treatment, in particular to a pig raising wastewater treatment system. Background technique [0002] The wastewater produced by pig farms often has high N and P organic matter content, and the number of disease microorganisms seriously exceeds the standard. If it is not treated and discharged into the surrounding water environment, it will often cause eutrophication of the water body and cause certain safety for animals and plants in the water body. Threat, large-scale professional pig raising enterprises have manure treatment biogas projects, generally adopt anaerobic digestion technology to process a large number of fresh pig manure and wastewater from live pigs, all manure is washed into anaerobic reactor for treatment, The biogas generated during the treatment process can be used for power generation, and the generated biogas slurry can be used for farmland irrigation after aerobic treatment, thus r...

[0002] The wastewater produced by pig farms often has high N and P organic matter content, and the number of disease microorganisms seriously exceeds the standard. If it is not treated and discharged into the surrounding water environment, it will often cause eutrophication of the water body and cause certain safety for animals and plants in the water body. Threat, large-scale professional pig raising enterprises have manure treatment biogas projects, generally adopt anaerobic digestion technology to process a large number of fresh pig manure and wastewater from live pigs, all manure is washed into anaerobic reactor for treatment, The biogas generated during the treatment process can be used for power generation, and the generated biogas slurry can be used for farmland irrigation after aerobic treatment, thus realizing the resourceful, harmless and ecological reuse of pig farm manure. Oxygen reaction is to carry out anaerobic reaction in the process of raising pigs. Large solids or substances that cannot be reacted by anaerobic bacteria enter the reaction tank, which reduces the treatment speed of sewage and increases the post-reaction process in the anaerobic tank. Increased the cost of pig wastewater treatment, so it is necessary to manually use a mesh screen for preliminary treatment of suspended solids, and then use a filter device to filter large solids before subsequent treatment

[0003] The traditional pig-raising wastewater treatment system has the following disadvantages: 1. The traditional pig-raising wastewater treatment system cannot mechanically remove suspended solids in the water. Suspended solids in the water such as plastic bags need to be salvaged manually, which increases the workload of the staff and makes the staff very 2. The traditional pig raising wastewater treatment system can only preliminarily filter the wastewater through the filter device, and another drying device is needed to dry the solid matter in the water, and the sediment in the water cannot be separated; 3. The traditional pig farming The stench emitted by the swine wastewater treatment system pollutes the environment, which cannot effectively reduce the stench and improve the environment
