The working principle of example 1 is now briefly described:
domestic wastewater enters the detection water tank 102 through the water inlet pipe 106 and the first water inlet, the laser emitter 103 located at the bottom of the detection water tank 102 emits laser, and due to the fact that the turbidity of the domestic wastewater is different, the light transmittance is different. The domestic wastewater with low turbidity has high light transmittance, the laser sensor 104 opposite to the domestic wastewater with low turbidity has high laser intensity, the domestic wastewater with high turbidity has low light transmittance, the laser sensor 104 opposite to the domestic wastewater with high turbidity has low laser intensity, and the data processing module judges and detects the pollution degree of the domestic wastewater in the water tank 102 through the laser intensity value signal of the laser sensor 104.

When the laser intensity value is higher than the preset light intensity threshold value, the pollution degree of the wastewater is low, the wastewater has recycling value, the main controller 105 controls the first electric valve 107 to be closed and the second electric valve 109 to be opened, the wastewater with low pollution degree flows into the filtering device to be filtered, the filtered water is pumped into the water storage tank 112 by the water pump 111 to be stored, and the water stored in the water storage tank 112 is used for flushing a toilet, cleaning a mop and cleaning articles which are not in direct contact with a human body in a water pump or self-flowing mode, so that the purpose of secondary reuse of the wastewater is achieved. The electric valve has large opening and stable performance.
The progressive selective wastewater recovery and purification equipment can monitor and analyze wastewater entering the detection water tank 102, discharge severe wastewater which is difficult to purify and low in recovery value, retain mild wastewater which is easy to purify, and selectively treat the wastewater to improve the economy of wastewater treatment.
Example 2:
on the basis of embodiment 1, in order to reduce the sewage treatment threshold value when the water level in the water storage tank 112 is higher, and further selectively treat the sewage with lighter pollution degree when the water level in the water storage tank 112 is higher, the economy of the wastewater treatment is improved.
As shown in fig. 1, a water level meter 5 is further disposed in the water storage tank 112, the water level meter 5 is electrically connected to the data processing module, the water level meter 5 detects the water level in the water storage tank 112 in real time and transmits a water level signal to the data processing module, a three-gear water level value is preset in the data processing module, each water level value corresponds to a preset light intensity threshold value, each water level value is in direct proportion to the preset light intensity threshold value, and the data processing module compares the real-time water level signal with the preset three-gear water level value to determine the preset light intensity threshold value.
Detect the water level in the storage water tank 112 in real time and transmit the water level signal to data processing module through water level appearance 5, thereby data processing module does the contrast with three grades of water level values of predetermineeing real-time water level signal and confirms dirty preset light intensity threshold value, because every grade of water level value is directly proportional with predetermineeing the light intensity threshold value, consequently, when the water level is high in the storage water tank 112, improve and predetermine the light intensity threshold value, when the water level is higher in the storage water tank 112, the more light waste water of further selective processing pollution degree, thereby promote waste water treatment's economic nature. Furthermore, a display is arranged on the controller 105, the height of the water level can be seen through the display, when the water level in the water storage tank 112 exceeds the standard, the controller 105 controls the first electric valve 107 to be opened and the second electric valve 109 to be closed, and therefore redundant waste water is directly drained away.
