The utility model relates to sewage treatment technical field, and disclose sewage treatment equipment, including septic tank main part, the feed pipe and the overflow pipe of setting respectively at septic tank main part both sides and the exhaust hole of setting at septic tank main part top, the inside fixed coupling of exhaust hole has the exhaust pipe, the utility model discloses a wind inlet pipe, air outlet pipe and air passage are set, when meeting windy weather time, the outside airflow flows in the wind inlet pipe, air passage and air outlet pipe inside, owing to'venturi effect' can accelerate the air flow speed from below to upwards in the exhaust pipe inside, the stench produced in septic tank main part can be discharged more quickly, reduced the accumulation time of stench in septic tank main part, and the efficient stench discharge is helpful to keep the relative cleanness of the air in the septic tank main part pool inside, and this design prevents the stench reflux, prevents the indoor environment from being contaminated, creates a more healthy, comfortable living environment for the residents.

This invention discloses a high-throughput photon-counting lidar imaging device and method. The device includes a beam transceiver module, a scanning module, a control module, a detection module, and a data processing module. The control module controls the scanning module to change the direction of the pulsed laser output to achieve target scanning. The detection module includes a single-photon detector and a time-correlated single-photon counting acquisition unit. A synchronization signal acquisition channel is connected to the pulsed laser to acquire the pulsed laser synchronization signal. This invention introduces a single-photon detector with photon number resolution, enabling simultaneous detection of multiple echo photons and simultaneous response to different photon counts. This invention effectively solves the limitations of traditional photon-counting lidars due to low-throughput and weak-light operating conditions, effectively improves the acquisition efficiency of echo photon information under high-throughput conditions, greatly reduces pulse accumulation time, and can achieve higher dynamic range and faster target detection.
