Embodiment 1

[0041] like figure 1 As shown, the biogas slurry NH 4 + -N online monitoring and safety utilization control system, including more than one set of soil moisture monitor 1, NH 4 + -N online monitor 2, central system control box 3, biogas slurry tank, reservoir, fertilizer dispenser 18, tertiary 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 the greenhouse. Inner soil moisture, the processing chip 120 collects the signals of the plurality of probe moisture sensors 110 and processes them;

[0043] The three-stage irrigation pipe network is composed of a main pipe 14, branch pipes 15 and end pipes 16, the diameters of which decrease in turn. The main pipe 14 is connected with...

Embodiment 2

[0060] like image 3 As shown, the biogas slurry NH 4 + -N online monitoring and safe utilization control system, including NH 4 + -N online monitor 2, central system control box 3, biogas slurry tank, reservoir, irrigation pipeline 14, pump room, frequency converter 6, turbine mixer 17;

[0061] The pump house is composed of a biogas slurry pump 4 and a water pump 5. The biogas slurry tank is a two-format biogas slurry tank. The external biogas slurry is initially precipitated in the sedimentation tank 8, and filtered by the grid 9 into the storage tank 10, which effectively removes the biogas slurry. The large particle filter screen box 12 is placed in the biogas slurry storage tank 10 for further biogas slurry filtration. The large particle filter screen box 12 is designed with a rectangular stainless steel frame, a backwash device, three sides Wrapped with 40-60 mesh stainless steel mesh, the opening of the filter mesh box is upward, placed vertically in the biogas slu...

Abstract

The invention discloses an online monitoring and safe utilization regulating system for NH4<+>-N in biogas slurry. The system comprises an NH4<+>-N online monitor, a central system control box, a biogas slurry pond, a water reservoir, an irrigating pipeline, a pump room, a frequency converter and a turbine agitator, wherein the pump room comprises a biogas slurry pump and a water pump, the connected position of the biogas slurry pump and the irrigating pipeline is closer to a water outlet of the irrigating pipeline than the connected position of the water pump and the irrigating pipeline; the central system control box receives and processes signals from the NH4<+>-N online monitor, and the operation of the water pump is directly controlled; the operation of the biogas slurry pond is controlled by the frequency converter; the turbine agitator is arranged in the irrigating pipeline and close to the water outlet of the irrigating pipeline. The invention also discloses a use method of the online monitoring and safe utilization regulating system. The NH4<+>-N online monitor is used for monitoring the biogas slurry before irrigation in real time, the application proportion of the biogas slurry to water is guided according to monitoring results, the operation control based on application safety of NH4<+>-N is realized, the growth safety of crops is guaranteed, and the effective basis is provided for scientific and reasonable utilization of the biogas slurry.

Description

technical field [0001] The present invention relates to a kind of biogas slurry NH 4 + -N on-line monitoring and safety utilization control system and using method thereof. Background technique [0002] In recent years, livestock and poultry breeding pollution has attracted widespread public attention and governments at all levels attach great importance to pollution control decisions. In order to realize the harmless treatment of manure and energy utilization, livestock and poultry farms have built biogas projects. The benefits also produce a large number of by-products, namely biogas slurry. Biogas slurry is rich in nitrogen, phosphorus, potassium, NH 4 + -N, etc., the direct discharge to the environment without subsequent treatment will have a serious impact on the self-purification function of the surrounding water bodies, which has become a key problem to be solved urgently in water environmental protection, and has also plagued the healthy development of animal hus...
