Wastewater treatment apparatus capable of being rapidly installed in the field

Abstract

The invention relates to a wastewater treatment apparatus capable of being rapidly installed in the field. The wastewater treatment apparatus sequentially comprises a capsule type wastewater collection container, a pressurizing pump, a sand carbon filter, an ultra-filtration filter, an active carbon filter, a NF nano-filtration membrane filter, an ultraviolet ray disinfector, a capsule type purified water collection container and a backwashing water pump, wherein the backwashing water pump is respectively connected to the water outlet of the sand carbon filter, the water outlet of the ultra-filtration filter and the water outlet of the active carbon filter through a fifth valve, the water inlet of the sand carbon filter, the water inlet of the ultra-filtration filter and the water inlet ofthe active carbon filter are connected to the capsule type wastewater collection container respectively through a sixth valve, a seventh valve and an eighth valve, and the wastewater outlet of the NFnano-filtration membrane filter is connected to the water inlet of the ultra-filtration filter through a ninth valve. Compared with the wastewater treatment apparatus in the prior art, the wastewatertreatment apparatus of the present invention can meet the rapid arrangement requirements of field battle, and can effectively treat wastewater.

Description

Technical field: [0001] The invention relates to a waste water treatment technology. Background technique: [0002] Existing field hospitals will produce a large amount of medical wastewater. If the wastewater is not properly treated, it will cause serious damage to the environment. The field emergency medical treatment is very different from the general traditional medical wastewater: (1) The implementation period is short: according to the past According to actual emergency experience, the general field emergency time is about 20 days. In such a short period of time, it is very unrealistic to use traditional treatment methods (biochemical treatment) to completely treat wastewater. There are two reasons: 1) The traditional medical wastewater treatment process must be biological treatment, and the physical and chemical treatment process cannot meet the discharge requirements; 2) The shortest start-up time of the biological treatment process is basically completed within 20-3...

[0002] Existing field hospitals will produce a large amount of medical wastewater. If the wastewater is not properly treated, it will cause serious damage to the environment. The field emergency medical treatment is very different from the general traditional medical wastewater: (1) The implementation period is short: according to the past According to practical emergency experience, the general field emergency time is about 20 days. In such a short period of time, it is very unrealistic to use traditional treatment methods (biochemical treatment) to completely treat wastewater.

There are two reasons: 1) The traditional medical wastewater treatment process must be biological treatment, and the physical and chemical treatment process cannot meet the discharge requirements; 2) The shortest start-up time of the biological treatment process is basically completed within 20-30 days, that is to say, the system None of them have fully started and operated normally, and the entire emergency incident has ended;

[0003] (2) Large fluctuations in water quality and quantity: The traditional medical wastewater biological treatment method has the characteristics of weak shock load resistance. In case of emergency in the field, it is not very realistic to build a regulating tank with sufficient capacity to meet the regulation of wastewater water quantity and water quality homogenization. This will easily lead to the instability of the biochemical treatment system, and it is difficult for the effluent to reach the standard stably;

[0004] (3) Unstable drainage destination: The drainage direction of emergency wastewater in the field is uncertain, which puts forward high requirements on the stability of wastewater treatment. To fully guarantee the quality of wastewater discharge;

[0005] (4) Disinfection must be carried out, but chemical disinfectants are not suitable: According to the national medical wastewater treatment regulations, medical wastewater must be disinfected before discharge, which is a rigid requirement, but traditional medical wastewater disinfection uses chemical disinfection, which exists One problem is that a certain amount of chemical agents must be carried, which brings certain risks and uncertainties to emergency medical treatment.

[0006] Therefore, it is impossible to use conventional hospital treatment methods. The existing treatment methods often only use container packaging and then landfill. Although it can prevent direct discharge from harming the environment, if these are easy to be unintentionally excavated and destroyed later. If it is opened, because the wastewater is still in a harmful state, there will be hazards. Moreover, the landfill of a large amount of medical wastewater requires a large area of ​​landfill, so that the landfill will definitely cause a relatively large impact on the environment. of potentially harmful
