Pig farms use centralized breeding and collective feeding. The sewage sources are mainly pig manure, pig urine and pig house rinsing water. Pig manure and pig urine themselves have a certain acidity, and the concentration of organic pollutants is quite high. If they are not directly discharged without treatment, it will seriously affect the surrounding water quality, cause soil acidification, and cause problems for the domestic water of nearby residents. To this end, according to the relevant provisions of the Environmental Protection Law, sewage discharged from breeding sites must be treated, and the treated effluent must be ecologically returned to the field or reused as flushing water for pig houses. Our company is a manufacturer engaged in the development of various water treatment projects and equipment. It has the ability to investigate, design, equipment manufacture, complete engineering, architectural design, construction, installation, commissioning and service of the managed projects, and can independently undertake and complete various water treatment projects, that is, turnkey projects. Based on the amount of wastewater provided by the owner, drawing on the actual operation experience of related projects, and in accordance with the principles of saving investment, good treatment effect and low operating cost, this design plan has been prepared for the decision reference of the owners and relevant departments. Description: Implement the “Pollutant Discharge Standard for Livestock and Poultry Breeding Industry” (GB18596-2001). Treatment process 02 0202 The sewage treatment equipment of pig farms is compared according to the above analysis. At the same time, according to the characteristics of the wastewater itself, 02 the treatment process with biochemical treatment as the core, supplemented by physical and chemical pretreatment facilities+biological treatment process facilities, to ensure that the effluent meets the standard discharge standards. Features of aquaculture sewage treatment equipment 1, integrated sewage treatment equipment has a high degree of modularity, can treat sewage in parallel, 2, sewage treatment equipment is small in size, light weight, easy to transport, easy to install; 3, sewage treatment equipment is made of FRP, carbon steel, stainless steel anticorrosive structure, has excellent characteristics such as anti-aging; 4, saving floor area, aquaculture sewage treatment equipment can be fully buried, semi-buried and ground Down, It can also be placed on the ground; 5. Sewage treatment equipment has no odor, and reduces secondary pollution; 5. The sewage treatment equipment is flexible and can be used individually or in combination. 6. The sewage treatment equipment is equipped with PLC automatic control system and fault alarm device, and it operates without special management. 7. Sewage treatment equipment later operating cost low sewage treatment project construction process Sewage treatment project is an important part of urban municipal construction, industrial enterprise construction or sewage discharge standard treatment. Its construction must be carried out according to capital procedures. The current capital construction procedures are generally divided into project proposals, project feasibility studies, project engineering design, engineering and equipment bidding, project construction, completion acceptance, operation commissioning and There are a few steps to meet the standards and acceptance. These construction steps basically include the whole process of project construction, and they can also be divided into three stages. At the initial stage of project establishment, the necessity and feasibility of project construction should be analyzed in accordance with the requirements of urban municipal planning or environmental protection departments. This stage focuses on determining the project. Generally, the construction unit or the design and research unit commissioned by the construction unit prepares the project proposal and the project feasibility study report. The project can be established through the demonstration by the planning department, the investment bank or the enterprise planning department. For some small-scale projects, only the sewage treatment project plan design is prepared and the project can be established through the demonstration of the investment department. Stage project construction stage. It includes engineering design, engineering and equipment bidding, project construction, completion acceptance, etc. 02
