example 1

[0152] 1) Pot selection: select pots with a diameter of 60cm or 60cm.

[0153] 2) Soil loading: 80% of biochar soil, 10% of sandy soil and 10% of crushed straw are stirred evenly, and then naturally loaded. Adjust the pH of the soil to 6.

[0154] 3) Water adjustment: the moisture content of the cultivation soil is controlled at about 20%.

[0155] 4) Draining salt: Since the salt content of the mixed cultivation soil in this embodiment is too high (leach solution TDS3000mg / l), it is necessary to drain the salt with water. With 100kPa water pressure and 15L / H water flow, keep for 20 minutes, 5 times, 10 hours between each time.

[0156] 5) Stabilization: Since the proportion of sludge production used in this embodiment exceeds 50%, a slight blast is required to speed up the process of decomposing and stabilizing. The blast working pressure is 700 mm water column, the air flow rate is 60L / H, for 10 consecutive days, each time for 1 hour, with an interval of 4 hours.

example 2

[0162] 1) Pot selection: select pots with a diameter of 40cm or 40cm.

[0163] 2) Soil loading: 30% of biochar soil, 10% of cultivated soil, 50% of sandy soil and 10% of crushed straw, mixed evenly, and then loaded naturally. Adjust the pH of the soil to 7.

[0164] 3) Water adjustment: the moisture content of the cultivation soil is controlled at about 20%.

[0165] 4) Plant rose seedlings.

[0166] 5) Maintenance: In summer, the working water pressure of micro-irrigation is 50-100kPa, and the water flow rate is 10-15L / H, with an interval of 5-7 days, 1-2 times a day, 0.5 hours each time; in winter, the working water pressure of micro-irrigation is 50kPa, The water flow rate is 10L / H, and the interval is 10-15 days, once a day, 0.5 hours each time. However, it must be noted that once the phenomenon of yellow leaves occurs, the temperature of the cultivation soil must be measured in time. If it is too high, the micro-blast system and micro-irrigation system need to be turne...

[0170] 1) Pot selection: select pots with a diameter of 60cm or 60cm.

[0171] 2) Soil loading: 50% of biochar soil, 40% of sandy soil and 10% of crushed straw are stirred evenly, and then naturally loaded. Adjust the pH of the soil to 8.

[0172] 3) Water adjustment: the moisture content of the cultivation soil is controlled at about 20%.

[0173] 4) Stabilization: Since the proportion of sludge production used in this embodiment exceeds 50%, a slight blast is required to speed up the process of decomposing and stabilizing. The blast working wind pressure is 700 mm water column, the air flow is 60L / H, for 5 consecutive days, each time for 1 hour, with an interval of 4 hours.

[0174] 5) plant Albizia juliensis seedlings.

[0175] 6) Maintenance: In summer, the working water pressure of micro-irrigation is 100-150kPa, the water flow rate is 15-20L / H, the interval is 5-7 days, 1-2 times a day, 0.5-1 hour each time. The working water pressure of micro-irrigation in winter is...

Abstract

The invention relates to an urban venous industrial park. Municipal solid waste is divided into old home appliances, construction waste, household waste, food waste, sludge, faeces and other biomass waste by a household waste separating system; the household waste is divided into dry waste and wet waste by a dry and wet separation device; the old home appliances, the construction waste and the dry waste are treated by a fossil waste processing system so as to form glass, plastic, metal, refuse derived fuel and recycled materials, and additionally, the fossil waste processing system is respectively connected with a generating system and a heating system; and the wet waste, the food waste, the sludge, the faeces and the other biomass waste are treated by a biomass waste processing system so as to form recycled water, biological carbon soil, methane gas and carbon dioxide. According to the urban venous industrial park, a resource-product-renewable resource closed-loop mode is realized, and the waste is changed into valuables and is recycled.

Description

technical field [0001] The invention relates to the field of energy and environmental protection, in particular to an urban venous industrial park and its construction method, as well as a solid waste treatment system and method. Background technique [0002] my country's urban waste treatment lacks top-level research, lacks in-depth research on the origin of waste generation and corresponding classification methods, and lacks theoretical guidance in the practice of waste classification collection, treatment and disposal, which leads to low levels of waste treatment efficiency and benefits. Due to the lack of top-level theoretical guidance, the technical research and development and application of urban waste treatment in my country have unclear footholds and starting points, and the fundamental goal is unclear. They often rely on achievable and single "harmless" treatment technologies to dominate the process route of waste treatment. To a certain extent, it deviates from the...
