The invention discloses a laser-scattering-based air quality detecting system. The laser-scattering-based air quality detecting system is characterized by comprising a laser transmitting system, a laser receiving system and a sample tank, wherein the laser transmitting system is provided with a laser source and a first photoelectric receiver; the laser emitted by the laser source sequentially passes through a polarizer, an aperture diaphragm, a first condensing lens, a first light splitting mirror and a second condensing lens and then irradiates the sample tank; the other path of light split by the first light splitting mirror irradiates the first photoelectric receiver; the laser receiving system is provided with a third condensing lens and a second photoelectric receiver. The laser-scattering-based air quality detecting system has the remarkable effects of being simple in structure and convenient to mount; the air quality is detected by the laser scattering manner; the light source cost is reduced; the plurality of photoelectric receivers are arranged, so that the system can be effectively corrected; the problem of unstable light source intensity can be solved; the detection accuracy is ensured; the detection requirement of the air quality can be met.
