Embodiment 1
[0041] like figure 1 As shown, the biogas slurry COD online monitoring and safe utilization control system includes more than one set of soil moisture monitor 1, COD online monitor 2, central system control box 3, biogas slurry pool, water storage tank, and fertilizer distribution device 18 , Three-level irrigation pipe network, pump room, solenoid valve 13, frequency converter 6;
[0042] The soil moisture monitor 1 is composed of a plurality of probe moisture sensors 110, a processing chip 120, and a control panel 130. The probe moisture sensors 110 are evenly distributed in the greenhouse area controlled by the soil moisture monitor 1 for detecting greenhouse Internal soil moisture, the processing chip 120 collects and processes the signals of a plurality of probe moisture sensors 110;
[0043] The tertiary irrigation pipe network is made up of main pipeline 14, branch pipeline 15, terminal pipeline 16, and its diameter decreases successively, and main pipeline 14 is conne...
Embodiment 2
[0060] like image 3 As shown, the biogas slurry COD online monitoring and safe utilization control system includes COD online monitor 2, central system control box 3, biogas slurry tank, water storage tank, irrigation pipeline 14, pump room, frequency converter 6, and turbine agitator 17;
[0061] The pump room is composed of a biogas slurry pump 4 and a water pump 5. The biogas slurry pool is a two-format biogas slurry pool. The external biogas slurry is initially precipitated in the sedimentation tank 8 and filtered through the grid 9 before entering the storage pool 10, effectively removing the biogas slurry. Larger particles of solid suspended matter in the liquid, and a large particle filter box 12 is placed in the biogas slurry storage tank 10 for further biogas slurry filtration, and the large particle filter box 12 is designed as a rectangular stainless steel frame, backwashing device, three sides 40-60 mesh stainless steel mesh wrapping, the opening of the filter ne...
