A complete separation and collection system for rainwater and sewage on coal wharf platforms

Abstract

This utility model discloses a complete separation and collection system for rainwater and sewage on a coal wharf platform. The coal wharf platform is equipped with a clear water pool and a sewage pool below it. A drainage pipe is pre-embedded along the wheel sill of the platform, connecting to the clear water pool. The drainage pipe opening is fitted with an internal plug-type sealing cap, which is normally closed. A sewage ditch is provided on the platform, connecting to the sewage pool. A water-blocking ditch is also installed along the bank of the sewage ditch, containing an inflatable rubber water-blocking bag connected to an air pump. At the start of rainfall, the rubber water-blocking bag is not inflated, and the drainage pipe opening is normally closed. Initially, the coal wastewater flows into the sewage ditch. After 30 minutes, the rubber water-blocking bag is inflated, preventing subsequent rainwater from entering the ditch. Simultaneously, the internal plug-type sealing cap of the drainage pipe opening is opened, allowing subsequent rainwater to flow by gravity into the clear water pool via the drainage pipe. After the rainfall ends, the cap is closed, and the water-blocking bag is emptied, completing the complete separation and collection of initial coal wastewater and subsequent clean rainwater at the wharf.

Description

Technical Field

[0001] This utility model relates to the field of water transport engineering, and in particular to a complete separation and collection system for rainwater and sewage on coal wharf platforms. Background Technology

[0002] The existing coal terminal and general cargo terminal use the same stormwater and sewage separation and collection system. This involves drainage ditches along the length of the terminal, with cross slopes on both sides. Rainwater flows into the ditches and then into a stormwater collection tank at the end. Initial and subsequent stormwater runoff are separated in the collection tank. Initial stormwater is pumped to the treatment system, while subsequent stormwater overflows and is discharged. This system is more suitable for general cargo terminals and meets environmental protection requirements for initial stormwater collection. However, initial stormwater runoff from coal terminals is rich in suspended solids, organic matter, oil, and heavy metals, and has a high color. The traditional separation method allows initial coal wastewater and subsequent stormwater to enter the same drainage ditch, resulting in subsequent stormwater containing a large amount of coal wastewater pollutants that cannot meet discharge standards. If this system were to be combined with the initial coal wastewater and enter the subsequent treatment system, it would significantly increase the terminal's stormwater treatment costs. Utility Model Content

[0003] The purpose of this utility model is to provide a complete rainwater and sewage separation and collection system suitable for coal terminal platforms, addressing the lack of a dedicated rainwater and sewage separation and collection system.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A complete separation and collection system for rainwater and sewage on a coal wharf platform is provided. The coal wharf platform is equipped with a clear water pool and a sewage pool. A drainage pipe is pre-buried along the wheel guard sill of the coal wharf platform and connected to the clear water pool. The drain pipe opening is equipped with an inner plug-type sealing pipe cover, which is normally closed. A sewage ditch is provided on the coal wharf platform and connected to the sewage pool. At the same time, a water-blocking ditch is provided along the bank of the sewage ditch. An inflatable rubber water-blocking bag is installed in the water-blocking ditch, and an air pump is connected to the outside of the rubber water-blocking bag.

[0006] Further technology of this utility model:

[0007] Preferably, the clear water pool is located on one side of the wheel guard sill near the coal wharf platform, and the sewage pool is located on the other side.

[0008] Preferably, the water-blocking ditch is located on the coal wharf platform between the clear water pool and the sewage pool.

[0009] Preferably, the rubber water-blocking bag is submerged in the water-blocking ditch after being emptied, and after being inflated, the top of the rubber water-blocking bag is higher than the coal wharf platform, and its horizontal position is higher than the outlet of the drainage pipe.

[0010] The beneficial effects of this utility model are:

[0011] 1. By controlling the initial and later rainwater of the coal terminal platform to enter different collection systems through the above method, the rainwater and sewage of the coal terminal are completely separated. The operation is convenient and can solve the technical problem of the difficulty in meeting the environmental protection standards of the coal terminal.

[0012] 2. Coal wastewater has complex water quality and high treatment costs. This method can prevent rainwater from mixing with coal wastewater and entering the coal wastewater treatment system, greatly reducing the amount of coal wastewater and saving coal wastewater treatment costs.

[0013] 3. This method has little impact on the wharf structure and does not affect wharf operations during operation. It is applicable not only to newly built coal wharves, but also to wharves for other types of cargo with high environmental protection requirements and environmental protection renovation of old wharves.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1-2This embodiment provides a complete separation and collection system for rainwater and sewage on a coal wharf platform 1. A clear water pool 2 and a sewage pool 3 are provided below the coal wharf platform 1. φ150 drainage pipes 5 are pre-buried at intervals of 30m along the wheel guard sill 4 on the coal wharf platform 1 and are connected to the clear water pool 2. The drain pipe 5 is equipped with an inner plug-type sealing pipe cover 6, which is normally closed. A sewage ditch 7 is provided on the coal wharf platform 1 and is connected to the sewage pool 3. At the same time, a water-blocking ditch 9 is provided along the bank of the sewage ditch 7. An inflatable rubber water-blocking bag 8 is provided in the water-blocking ditch 9, and an air pump is connected to the outside of the rubber water-blocking bag 8.

[0020] The clear water pool 2 is located on one side of the wheel guard sill 4 near the coal wharf platform 1, and the sewage pool 3 is located on the other side.

[0021] The water-blocking ditch 9 is located on the coal wharf platform 1 between the clear water pool 2 and the sewage pool 3.

[0022] Based on the pollution characteristics of coal, drainage ditches and rainwater pipes are installed on the wharf platform, such as... Figure 1-2 As shown, during the first 30 minutes of a rainfall event, rainwater is collected through a drainage ditch and enters sewage tank 3, where it is pumped to the land-based coal-water treatment system for treatment. After 30 minutes, the rainwater becomes relatively clean and is collected along the rainwater pipe after passing through the dock and enters clear water tank 2, where it is pumped to the land-based rainwater collection system or discharged by a submersible pump.

[0023] In order not to affect the normal passage of the dock, the rubber water-blocking bag 8 is submerged in the water-blocking ditch 9 after being emptied. After being inflated, the top of the rubber water-blocking bag 8 is higher than the coal dock platform 1, and its horizontal position is higher than the opening of the drainage pipe 5.

[0024] At the start of rainfall, the rubber water bag is not inflated. The drain pipe 5 is equipped with an inner plug-type sealing cap 6, which is normally closed. Initially, the coal wastewater flows into the sewage ditch 7. The rubber water-blocking strip is inflated to prevent later rainwater from entering the sewage ditch. At the same time, the inner plug-type sealing cap 6 at the drain pipe 5 is opened. Later rainwater flows by gravity through the drain pipe 5 into the clear water pool 2. After the rainfall ends, the cap is closed and the water-blocking bag is emptied, thus completing the complete separation and collection of the initial coal wastewater and the later clean rainwater at the dock.

[0025] It should be noted that the water bag is made of a wear-resistant, easy-to-operate, thickened high-density rubber synthetic plastic material with a strength of 1.0 MPa.
