The present invention provides a pre-phosphorus removal and post-endogenous denitrification coupled MBR sewage treatment system and process. The system mainly includes a pre-phosphorus removal unit, a post-endogenous denitrification unit and a sludge return unit. The effluent from the grit chamber enters a flocculation sedimentation phosphorus removal tank for phosphorus removal; then the supernatant enters a post-endogenous denitrification unit, and denitrifying bacteria absorb carbon sources in the anaerobic tank. In the dynamic aerobic tank, dynamic and precise nitrification is carried out in conjunction with detection instruments and control equipment, and then post-endogenous denitrification is carried out in the anoxic tank, thereby achieving deep denitrification; the effluent and sludge from the anoxic tank enter the MBR membrane tank and the sludge return unit, and a double return system is adopted to maximize the function of the anaerobic zone, or a pre-anaerobic zone is set up to divert the influent and reduce the impact of high dissolved oxygen in the MBR membrane tank on the denitrifying bacteria. The system and process solve the problems of low denitrification efficiency of traditional pre-denitrification, the sludge age contradiction between post-biological phosphorus removal and denitrification, high suspended solids in biochemical effluent, and the inability to selectively increase sludge concentration in winter.

The invention provides a degradation-resistant wastewater treatment system, which comprises: a chemical oxidation system, which comprises an acid adjusting tank, an electro-Fenton reaction tank, an alkali adding neutralization tank and a solid-liquid separation tank which are sequentially connected along a water flow direction; and the biochemical system comprises a denitration selection tank, an anaerobic tank, an anoxic tank, at least one aerobic tank and an eMBR membrane tank which are sequentially connected along the water flow direction. Compared with the prior art, the non-degradable wastewater treatment system has the advantages that the denitration selection tank is additionally arranged at the front end of the anaerobic tank, nitrite nitrogen returned by sludge is removed by using a raw water carbon source, the influence on the growth of phosphorus-accumulating bacteria is reduced, the phosphorus removal effect is improved, an anaerobic ammonia oxidation generation environment is created, and the denitrification effect of the system is enhanced.

According to the method, origanum vulgare stops growing in winter and grows slowly in spring, selfheal grows on the ground surface in a rosette shape in winter and grows rapidly in spring, harvesting can be completed in late May, at the moment, origanum vulgare begins to enter a rapid growth period, and the yield of the origanum vulgare is increased. Due to the fact that the growth states of the origanum vulgare and the selfheal are inconsistent in different seasons, the maximum coverage of the land is achieved, the weed growth space is compressed, use of herbicides is avoided, and green prevention and control of weeds are achieved; according to the method, different growing periods of the origanum vulgare and the selfheal are utilized at the same time, the utilization rate of land is increased, natural resources such as light energy, air, moisture and heat can be fully utilized, the marginal effect and the mutual benefit effect between plants are exerted, the comprehensive benefit of double harvest is achieved, the income is increased, and the economic value is improved.

This invention provides a three-dimensional force data management method and system, relating to the management and communication of three-dimensional force data from tactile sensors. The method quantizes and compresses the X / Y / Z axis amplitudes of each three-dimensional force vector to 10 bits, and separately encodes the X and Y sign bits into 2 bits, forming a compact 32-bit representation of 10+10+10+2 bits. At the transmitting end, continuous three-dimensional force vector arrays are batch-packed into multiple 64-byte communication frames with 32-bit alignment and zero-copy, and then sent. At the receiving end, the three-axis force and direction information is quickly recovered through bitmasking and shifting. Simultaneously, addressing the bus contention problem caused by multiple nodes powering on in parallel, this invention utilizes a unique chip identifier and a hardware counter to generate multi-level random startup delays, enabling staggered initialization and transmission by multiple devices, thereby reducing frame loss and congestion. This invention has the advantages of data compression, fast parsing, low memory and bandwidth consumption, and high stability across multiple nodes, making it suitable for mass production deployment of tactile sensor products using real-time buses such as CAN / CAN-FD.

This invention belongs to the field of beverage preparation technology and discloses a parallel execution control system and method for a modular beverage preparation process. The method includes: acquiring orders and breaking them down into a set of step nodes according to the production process; combining step nodes from different orders in pairs within the step node set and obtaining conflict values; establishing a first echelon for execution and creating a first execution layer within the first echelon, selecting the step node with the lowest conflict degree with other step nodes as the first step node of the first execution layer; determining whether the remaining step nodes in the first echelon should be included in the first execution layer based on the conflict values; continuously creating new execution layers until all unincluded nodes are included; executing the first echelon in the order of execution layers, creating execution layers for subsequent echelons, and triggering the sorting of execution layers for subsequent echelons based on the completion conditions of step nodes. This invention improves the smoothness and efficiency of modular beverage preparation through multi-echelon, multi-execution-layer parallel scheduling driven by conflict values.
