Humen, Dongguan: Renovate The Printing And Dyeing Professional Base And Help The Green Development

Dongguan Humen town electroplating, printing and dyeing professional base for the old district integration base, enterprises in the 1990s have existed. Due to the lack of scientific planning for the early base construction, the relative confusion of pipe network layout, and the weak awareness of law-abiding in some enterprises, the early pollution was serious and there were many problems left over by history. In this regard, Humen Town is determined to renovate the source of pollution, focus on both pollution prevention and upgrading, establish a pollution prevention and control system led by the government, led by environmental protection, coordinated by departments, and jointly managed, so as to comprehensively and strictly control the pollutant discharge behavior of enterprises.

　　 Establishing rules and regulations to create "propeller" for work

First of all, Humen Town has set up a leading group for comprehensive renovation of electroplating printing and dyeing professional base. The leading group is composed of Humen town ecological environment sub Bureau, emergency management sub Bureau, urban management sub Bureau, industry and Information Technology Bureau, housing and Urban Rural Development Bureau, health and urban rural development Bureau, etc. to give full play to the management responsibilities of relevant functional departments, form a joint force, and coordinate the comprehensive renovation work of the base.

At the same time, Humen Town has also set up a base management office to implement the requirements of "three fixed" (fixed personnel, fixed factory, and fixed responsibility). The base enterprises are fully contracted to each other and tracked by special personnel to realize the full coverage of monthly inspection, so as to ensure that the investigation and punishment of environmental violations and the rectification of environmental problems are in place. At the same time, closed management was implemented for the base, sentry boxes were set up at the entrance and exit of the base, and the registration and inspection of truck opening were implemented to prevent the illegal transfer of solid waste and hazardous waste.

In addition, Humen Town worked out the work plan and task list, combined with the spirit of 2020 "Dongguan environmental protection professional base renovation work plan" and "notice on further clarifying the rectification and acceptance of various environmental protection professional bases in the city", etc., carried out the rectification task, and invited the expert group to inspect the rectification effect.

　　 Strengthen rectification and strictly control environmental "risk points"

The town also implemented the transformation according to the principle of "one in, three out". To realize the unified water supply of enterprises in the base, mark and separate the pipe network according to the rainwater open channel and sewage open pipe, and set up the special discharge outlet, install the online monitoring equipment of pH value and conductivity, and the emergency pumping system when the water quality is abnormal. The production wastewater, domestic sewage and rainwater are discharged separately.

And comprehensively standardize and drain drainage pipe network. All the production wastewater from enterprises in the base is connected to the sewage treatment plant of the base for centralized treatment, and the base sewage treatment plant uniformly supervises the risk problems brought by the production wastewater transportation of each enterprise; The domestic sewage of base enterprises is transported to Humen town sewage treatment plant through the newly built 4.4 km sewage pipe network, so as to eliminate the direct discharge of domestic sewage; The rainwater pipe network of the base is entrusted to the professional pipeline exploration unit to carry out dredging, exploration and repair in sections, so as to eliminate the potential hidden danger of sewage discharged through the rainwater pipeline.

Improve the base emergency plan and corresponding facilities. Meanwhile, we should supervise the enterprises in the base to complete the filing of emergency plan and corresponding facilities, strengthen the environmental security prevention, and effectively improve the prevention level of sudden environmental risks.

Carry out the "three wastes" rectification, formulate the "three wastes" (waste water, waste gas, hazardous waste) treatment plan, and report to Dongguan Ecological Environment Bureau for the record, continuously standardize the production wastewater classification, waste gas collection and treatment, standardized storage of solid waste and other rectification measures of enterprises in the base. Through continuous publicity and inspection, we can improve the environmental protection awareness of enterprises in the base and reduce the potential environmental risks.

　　 Supervision and law enforcement to crack down on environmental "destroyers"

In addition, Humen Town adheres to strict prevention at the source and strict control of the process, comprehensively strengthens the supervision and law enforcement, improves the deterrent power of on-site law enforcement through the joint law enforcement mode of environmental protection and public security, continuously carries out night inspection at least once a week, and consolidates the law enforcement effect by means of centralized military use and cross inspection. Since the beginning of 2020, a total of 10 environmental illegal enterprises have been registered, 3 key pollution enterprises have been eliminated, and 54 "scattered pollution" enterprises in the base and surrounding areas have been cleaned up.

Build the whole process intelligent monitoring platform, implement the installation of the whole process monitoring facilities at the enterprise end, install monitoring equipment such as metering or sensors in the key working conditions of the enterprise's production process, monitor the production conditions of water, electricity and drainage in real time, and upload them to the monitoring platform, so as to realize real-time monitoring of the whole process of the enterprise, forecast and early warning, It effectively improves the scientific, refined and information level of enterprise supervision.

Establish a long-term environmental protection working mechanism, realize the goal of industrial optimal gathering and environmental comprehensive treatment through centralized development and centralized pollution control, establish the responsibility management of key enterprises, and distinguish the supervision measures of key and non key enterprises in the base, continuously summarize the experience and lessons of pollution prevention and control, and constantly optimize the comprehensive supervision level, so as to make enterprises aware of the new era Under the new situation, we should update the business management concept, strengthen the investment in environmental protection, improve the level of environmental management, and improve the environmental status of the base.
