Problems solved by technology
However, in the alpine regions of northern and western my country, the effect of sewage treatment is greatly affected by the low temperature environment. With the decrease of water temperature, the activity of activated sludge gradually decreases, and the sedimentation becomes worse. The removal of organic matter, nitrification and denitrification are greatly impacted.

The invention relates to the technical field of sewage treatment in alpine regions, and provides an integrated low-temperature-resistant sewage treatment system, which comprises a solar power generation system, a sewage heating system and a sewage treatment system, wherein the solar power generation system utilizes the photovoltaic effect of a semiconductor interface to directly convert light energy into electric energy and mainly comprises a photovoltaic module, a controller and a grid-connected inverter, the sewage heating system can increase the temperature of a biochemical system in winter in a cold region, and consists of a wall-hanging stove, a heat exchange water tank and a heating circulating pump, the sewage treatment system utilizes the site space of a station to carry out solar photovoltaic power generation so as to provide power for the sewage treatment system, the sewage treated by a biochemical and MBR process reaches the standard to be discharged or recycled, the solar photovoltaic generating capacity exceeds / is lower than the power consumption for operation and heating of the system, and the power supply and demand balance is achieved through the regulation of the state grid. The system is a perfect combination of photovoltaic new energy and sewage treatment equipment.
Description
technical field [0001] The invention relates to the technical field of sewage treatment in alpine regions, in particular to an integrated anti-low temperature sewage treatment system. Background technique [0002] my country's carbon dioxide emissions strive to peak before 2030 and achieve "carbon neutrality" before 2060. This goal is forcing energy transformation, reducing energy consumption that produces carbon dioxide, and replacing traditional thermal power generation with renewable energy. [0003] The sewage treatment industry is also a major energy consumer. According to statistics, the power consumption of sewage treatment plants in my country accounted for 0.26% of the country's total power consumption in 2014, accounting for more than 2% including industrial wastewater treatment and sludge treatment. From the perspective of energy conversion, the traditional sewage treatment model essentially exchanges energy consumption for water quality. The process of sewage t...
