Embodiment 1

[0031] Example 1: Intelligent diagnosis and early warning decision-making method and system for hollow fiber membrane pollution of the present invention

[0032] (1) The principle of the invention: through the system integration of the online remote monitoring module, membrane pollution prediction module, membrane pollution assessment and early warning classification module, membrane system abnormal situation intelligent diagnosis and decision-making module, information resource management and human-computer interaction module, the system is constructed. Membrane fouling intelligent diagnosis and early warning decision-making platform (see attached figure 1 ). Among them, the above-mentioned modules constitute the software platform of the system, and the electromagnetic valves, pneumatic valves, flow meters, turbidity meters, pH meters, hardness meters and other intelligent instruments on the hollow fiber membrane equipment, as well as PLC, server, client and industrial Ethern...

Embodiment 2

[0063] Example 2: Membrane fouling intelligent diagnosis and early warning decision-making system used in continuous microfiltration equipment to treat wastewater from iron and steel enterprises

[0064] There is no conventional water supply source in a steel group. It adopts the method of centralized treatment and regeneration of multiple water sources such as production wastewater, domestic sewage, and rainwater to provide enterprises with circulating water and supplementary water for production and use. Wastewater is reused for multiple purposes after being treated by fine screen / grit chamber, hydrolytic acidification tank, CAST system, flocculation reaction tank / sedimentation tank, microfiltration and reverse osmosis, among which the continuous microfiltration membrane (CFM) system mainly The secondary effluent of the biological treatment of the sewage plant is subjected to advanced treatment to meet the requirements of multi-purpose reuse and reverse osmosis pretreatment. ...

Abstract

The invention belongs to the technical field of water treatment, and in particular relates to a membrane pollution intelligent diagnosis and early warning decision making system of a hollow fiber device. An online remote control module, a membrane pollution prediction module, a membrane pollution evaluation and early warning classification module, a membrane system abnormal circumstance intelligent diagnosis and decision making module, and an information resource management and human-computer interaction module are systematically integrated to build the membrane pollution intelligent diagnosis and early warning decision making platform, wherein the modules form the software platform of the system, and intelligent instruments on the hollow fiber membrane device such as an electromagnetic valve, a pneumatic valve, a flowmeter and turbidimeter, a pH meter and a hardness meter, and a PLC, a server, a client side and an industrial Ethernet form the hardware platform of the system. The system applicable for a plurality of hollow fiber membrane devices has the advantages of realizing convenient data exchange with an automatic system in the conventional device and improving the economic benefit of the integral membrane method separation process along with easy realization and wide application and popularization range.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to wastewater purification in the fields of sewage regeneration, reverse osmosis pretreatment and the like. More specifically, it is an intelligent membrane fouling diagnosis and early warning decision-making system for hollow fiber equipment. Background technique [0002] Wastewater recycling is an effective way to alleviate the tension of water resources and reduce environmental pollution. At present, methods such as ion exchange, electrosorption, ozone oxidation and electrodialysis all have problems such as excessive investment or high operating costs, and it is difficult to widely apply and promote them in engineering in the short term. The development of membrane separation technology has promoted the work of sewage treatment and reuse, especially the hollow fiber equipment has the characteristics of compact structure, simple and flexible equipment control, etc., and has ...
