The invention relates to a method for treating eutrophication pollution of landscape water, and combines a physical-chemical technique and an ecological floating island technique, utilizing a constructed enclosure to divide an ecological purification area and a strengthening purification area in the landscape water and plant an ecological floating island in the ecological purification area. Besides the ecological floating island planted in the strengthening purification area, a medicine feeding system and an aeration system are also arranged in the strengthening purification area; by utilizing a diving pump, the landscape water is led to the purification areas; the medicine feeding system and the aeration system are opened; through the effects of physical-chemical adsorption and coagulation settlement, pollutants are rapidly removed; at the same time, the ecological floating island closely distributed on the water surface has good effects of wind and storm resistance and light screening, thus providing a good hydraulic condition for the settlement of the pollutants; due to a loss of light source, the algae settling under water can not float any more, thus dying gradually; in addition, a certain quantity of nutrition salt released in a decomposition of the pollutants and dying of the algae can be fully absorbed by the ecological floating island; the high quality water treated in the ecological purification areas flows back to the landscape water.

The present invention is a new and innovative device for regulating parking permits in parking zones in which parking is permitted for short time spans. Embodiments of the present invention enable users to purchase reusable electronic parking devices which display the amount of time remaining for free parking. For instance, in parking zones which allow fifteen minutes of free parking, the device displays 15 min when turned on and counts back the minutes until the time is over. A delaying mechanism inhibits the reactivation of the device for a predetermined time period. Thus, the device ensures that the parking permit is only used for the predetermined time period once since users cannot activate the device sequentially. According to embodiments of the present invention the proposed system and method may be embedded into other time parking devices.
