The invention relates to an intelligent regional drinking water pollution source detection device, and provides a device for detecting pollutants in water by combining spectral detection and image detection. According to the device for detecting the pollutants in the water by combining the spectral detection and the image detection, a defect of a single detection method can be overcome, and the accuracy of detection is provided; a detection ship which can be applied to a water area is provided, the pollutants in a large area of a water body can be detected under the control of a cloud host, and detection results are displayed on a display device intelligently; and the cloud host can automatically identify the location of the pollutants with highest concentration and mark the pollutants with the highest concentration as suspected pollution sources. The invention provides a novel underwater long optical path length cell; the novel underwater long optical path length cell utilizes the characteristics of a superhydrophobic structure to form total reflection under water; and an automatic ultrasound cleaning device and a gas blowing device capable of supplementing gas are arranged, and the long and stable operation of the device is ensured.

The invention relates to the technical field of livestock breeding, and discloses a hydraulically driven livestock drinking device, which includes a fixed plate, the middle part of which is fixedly connected to a drinking trough, and the left side of the fixed plate is fixedly connected to a driving chamber. The present invention can be used in the water feeding work in the process of raising livestock. The device is provided with a driving chamber and a driven chamber to form a hydraulic driving device. Through the hydraulic driving device, each time the livestock stands in front of the drinking trough, the weight of the livestock can be reduced. Open the first baffle on the drinking trough, and the livestock can drink water normally. After drinking, the livestock leaves. Under the action of the spring, the first baffle slides to the left to cover the drinking trough again to prevent debris from falling into the drinking trough. It will pollute the drinking water and set up the automatic water replenishment function. The operator only needs to connect the water inlet pipe with the tap water pipe or the pipe of the water source to use it. The operation is simple and convenient, which improves the sanitation of livestock drinking water and is suitable for popularization. .

The invention discloses a dust-proof water dispenser which comprises a water bucket, a bucket cover for covering a nozzle of the water bucket, a first pipe, a second pipe, a transparent pipe, an air tank, a check valve and a sucking pump; an air inlet channel which is communicated with an inner cavity of the water bucket and allows air to enter therein is formed between the bucket cover and the nozzle of the water bucket; a connection pipe is arranged on the outer top wall of the bucket cover in an upward extending mode; the first pipe is inserted into the water bucket and communicated with the second pipe; the second pipe is in cup joint fit with the connection pipe; the lower end of the transparent pipe is communicated with the connection segment of the second pipe, and the second pipe further comprises a water inlet segment and a water outlet segment, wherein the connection segment is arranged between the water inlet segment and the water outlet segment and is in cup joint fit with the water inlet segment and the water outlet segment; the water outlet segment is provided with a valve, and the valve is used for controlling switching-on and switching-off of the water outlet segment; the highest point of the transparent pipe is higher than the highest point of the water outlet segment; the transparent pipe is communicated with one of air openings of the air tank through an air pipe, and the other air opening of the air tank is communicated with the sucking pump through the check valve. By means of the dust-proof water dispenser, dust entering the water dispenser can be reduced, and accordingly contamination of drinking water is avoided.

The invention provides a method for treating organic arsenic-containing water which can prevent drinking water from being contaminated by removing diphenylarsine acid representative as an organic arsenic contained in ground water. The method for treating the organic arsenic-containing water comprises a photo-oxidation process of irradiating raw water containing the organic arsenic including a bond between an organic group and an arsenic atom with light to dissociate the bond between the organic group and the arsenic atom, and a process of carrying out flocculation treatment of arsenic or an arsenic compound generated by dissociation in the photo-oxidation process, wherein the photo-oxidation process is preferably irradiated with light in the presence of ozone.

The invention belongs to the technical field of kitchens and bathrooms, and discloses a water faucet for a kitchen. The water faucet comprises a vertical pipe for fixed installation, a horizontal pipehorizontally arranged on the upper part of the vertical pipe and a handle. The water faucet is connected with a heating box through a pipeline, a filter for filtering tap water and a blower for generating airflow are correspondingly connected with one end of the heating box far away from one end connecting with the water faucet, and an electromagnetic oven is slidably connected with the bottom ofthe heating box. Drinking water and non-drinking water are discharged from the water faucet through the corresponding dedicated pipeline to prevent the non-drinking water from polluting the drinkingwater, a drinking water outlet head extends out of a drinking water outlet only when an electromagnetic valve corresponding to the drinking water is open, and automatically retracts to the inside of the water faucet when the electromagnetic valve corresponding to the drinking water is closed to prevent the outside environment from polluting a valve tube.
