Integrated treatment device for aquaculture wastewater and treatment method of device

Abstract

The invention relate to an integrated treatment device for aquaculture wastewater. The device comprises a pretreatment component, an anaerobic component and an SBR component which are sequentially connected, wherein a portable grid, a regulating tank, a pneumatic lifting pump and a coagulation sedimentation tank are arranged on the pretreatment component; the anaerobic component comprises an ABR (Anoxic Baffled Reactor) reaction tank and a tail gas collection processor; an ABR reactor is connected with the coagulation sedimentation tank through a pipeline; the SBR (Sequencing Batch Reactor) component comprises an SBR reaction tank, a water distributor and an aeration device; the aeration device comprises multiple groups of diaphragm microporous aeration trays; and a clarification tank is connected with the SBR reaction tank. The device further comprises an automatic control component, wherein the automatic control component comprises a PLC (Programmable Logic Controller). The treatmentdevice has the advantages of reasonable structural design, low energy consumption, simple and convenient operation, relatively high degree of automation and intelligence, energy conservation and environmental protection. The treatment device can effectively remove suspended substances in aquaculture water by strengthening pretreatment, and adopts a combination of anaerobic and aerobic methods toreduce the energy consumption of sewage treatment while improving the treatment efficiency of the equipment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to an integrated treatment device for aquaculture wastewater and a treatment method thereof with simple equipment, low energy consumption and simple operation, and is suitable for occasions such as small and medium-sized aquaculture farms. technical background [0002] According to public data, the number of dairy cows in the country was 14.7 million in 2014 and 15.94 million in 2015. my country's dairy industry is in a period of rapid development. Compared with developed countries, the output value of China's dairy industry accounts for 10% of the total domestic animal husbandry, which is much lower than the 40% in developed countries, and there is still a lot of room for development. With the continuous improvement of children's nutritional needs, parents' demand for high-quality dairy products is increasing. The discovery of my country's dairy industry h...
