The invention discloses a sewage collection and automatic discharge well which comprises a gravity collection pipe, a well body, a sewage discharge pipe, a vacuum valve and a vacuum pipe. The vacuum valve comprises a work cavity, a pilot valve communicated with the work cavity, a medium inlet in butt joint with the sewage discharge pipe and a medium outlet connected with the vacuum pipe. The vacuum pipe is further provided with an air taking opening; the pilot valve is provided with a vacuum connector in butt joint with the air taking opening, an atmosphere connector communicated with the atmosphere and a pressure connector for sensing the liquid level in a well body; the pressure connector is further provided with a sensitive element downwards extending to the well body. According to the sewage collection and automatic discharge well, the opening and closing power of the vacuum valve comes from a vacuum system, opening and closing can be achieved without adding extra power equipment, the power loss of the system is lowered, safety is higher, meanwhile the sewage collection and automatic discharge well has the advantages of automatic collection, quantitative discharge and being free of manual guard, and the sewage collection and automatic discharge well is simple in structure and convenient and practical.

The invention discloses a vacuum sewage collecting and treating system. The vacuum sewage collecting and treating system comprises a sewage gathering pipeline, a vacuum collection well, a vacuum conveying pipeline, a vacuum pump station and a sewage treating device, wherein the sewage enters the vacuum collection well through the sewage gathering pipeline; when the sewage collected in the well reaches a certain amount, the sewage enters the vacuum pump station along the vacuum conveying pipeline; when the liquid level of the sewage in a vacuum sewage storage tank reaches a predetermined liquid level, the sewage conveying pump is started and is used for conveying the sewage to the sewage treating device to purify the sewage. Through the vacuum sewage collecting and treating system, the domestic sewage collection method is changed from the conventional gravity collection into vacuum collection; the sewage treatment is charged from a manner of discharging the sewage into a sewage pipe net and carrying out centralized treatment on the sewage to a process of carrying out on-site treatment by using a small integrated membrane treatment device; collection and treatment are integrated to a complete set of system; the system is not limited by basic supporting facilities and is not required to relay on urban drainage facilities; the system is integrated with the ecological environmental protection technology with efficient collection and efficient treatment functions and is especially suitable for regions such as small towns and countries and the like in which sewage treatment plants are unsuitably built.

The invention discloses a nutrient soil for tea tree mushroom cultivation and a recycling method thereof. The nutrient soil includes cottonseed hulls, wheat husks, peat, coconut bran, sawdust, lime, bagasse, corncobs, compound nutrient soil, organic fertilizer, Urea, Potassium Phosphate. The recycling method includes: (a) reclaiming the waste nutrient soil for the first time; (b) installing a nutrient soil collection frame; (c) recycling the waste nutrient soil for the second time; (d) spraying itaconic sour yeast liquid; (e) ) Install waste nutrient soil discharge device; (f) load into nutrient soil collection frame; (g) quantitatively discharge waste nutrient soil; (h) recycle empty nutrient soil collection frame; (i) continuously discharge waste nutrient soil; (j) Discharging the packing material. The nutrient soil of the present invention has a loose outer structure and a firm inner structure, good permeability, strong water storage capacity, rich nutrient content, and improved yield of harvested tea tree mushrooms. The invention recycles the waste nutrient soil, has good waste gas treatment effect, and reduces the cultivation cost of tea tree mushroom.

The invention discloses a banknote dispensing gate device of an automatic teller machine, which comprises a circuit control board, a mechanical part and a DC motor. The circuit control board is fixed on the side of the mechanical part, and the DC motor is fixed on the lower part of the mechanical part. The present invention provides a self-contained microprogram controller unit for a banknote dispensing gate device of an automatic teller machine, which can directly control the gate through the command of the host computer, and the opening and closing of the gate no longer depends on the control of the cash dispensing module; the structure is reasonable and the design is very Waterproof and dustproof are well taken into consideration, and it is more stable, safer and more reliable than the existing banknote dispensing gate device; the USB port is added, the interface is more abundant, the application area is wider, and the control and maintenance are convenient.

The invention discloses a remote management system and a remote management method of optical fiber multiplexing equipment. The remote management system comprises a data acquiring and packaging module as well as a main control module, wherein the data acquiring and packaging module is used for acquiring hardware information of the optical fiber multiplexing equipment, packaging the acquired hardware information into messages, and sending the messages to the main control module; the main control module receives the messages sent by the data acquiring and packaging module and further packaging the messages into TCP protocol messages, so that the hardware information can be transmitted to a management and control device by an Ethernet local area network, so that data can be interacted by the network and the management and control device. According to the system and the method, based on the Ethernet, the management and control device can be used for managing and controlling the optical fiber multiplexing device, and the space limitation is broken, so that the management and control maintenance of the optical fiber multiplexing device is relatively convenient.
